DIY Interconnects review


Category: Cables

In an attempt to live up to a comment I made on a thread that was discussing interconnects and the over inflated costs, I agreed to do some research and try to build my own interconnects. I could then use fact in my discussions of the value of the manufactured cables. I did intense research for about four months, reading as much as I could on Audiogon, Audio Asylum, web sights dealing with designs by Chris VenHaus, Jon Risch and Allen Wright. I also attempted to go to all the manufacturers web sites and read what they had as a philosophy. Please forgive me for the length of this post, but it was important to me to be thourogh in my methodology so as to help those reading this understand the mission.

It should come as no surprise to most of you, there are as many opinions on what makes a good interconnects as there are companies. Dispite this fact, most every interconnect made today both profesionally and DIY have common methodogy in construction. Most every design I read about starts with a core, has any number of wires coming in a wide array of materials that are wound around the cord. Then the dielectric is created, again using most any material one can dream of. This is followed by most companies and DIY’s using some type of EMI/RFI sheilding. Then some type of fancy casing is used so that the cable looks nice. The casing is generally connected to the connector with shrink wrap and often some type of reinforcement to allow for the users who pull out their interconnects by the wire and not the plug.

Great I thought! Clearly these are all logical components that are being used, and of course I figured there was some science behind all this construction. In fact Cardas is using the Golden Ratio (first dirived in Ancient Greece) so this must be good. Not only is every wire praportional to the other, but the shielding (all nine layers) are also applied using this ratio. Now don’t get me wrong, The Golden Ratio is often used in my profesion of Architecture, it was conceptualized my DiVince the was incorporated in Michelangelo’s St. Paul’s Cathidal, and it has been used ever sense, but audio cables???

Well I took all the ideas I could find and went off to my (three) local Radio Shacks to buy their entire inventory of gold plated RCA connectors. I also picked up a better solder station, a good de-soldering devise, copper wire of every size as well as robbing my local hardware stores of foam backer rods, Teflon tubing, Teflon tape, cottom rope, poly-something tubing and any other thing that looked cool. Total cost of components was roughly $300 ($20 each pair of interconnects) and enough stuff to supply every friend I know with interconnects.

So my first generations started with the pholosophy that more is better, so I built some interconnects using 14 ga wire twisted around a 1/2” teflon tube. I tried one two and three wires per positive and negitive run in equal and unequal combinations. I then built the same concepts using 18ga, then 22ga, 24ga, 26ga, 28ga and finally 30ga. I then repeated the process using a 1/2” Teflon and 1/2”, 3/8” or1/4” cotton rope. On these mock ups I wanted to hear the wire and core intraction with no other variable so I used only cotton thread to hold the bare wire to the core. In each case I listened for a short time to get some concept of what these designs were doing, but only in comparison to one another. I was not yet listening for musicality nor even technical aspects, only an overall concept. I often dragged my friends into this to get a second opinion, but really this was easy to distinguis.

FIRST MYTH EXPOSED: WIRE DOES MAKE A DIFFERENCE! Do not allow anyone to tell you otherwise. If they clain wire is wire, then they either have no experience with a decent system, or no experience trying cables.

It became clear to me that the thicker wire was woolyer , fuzzier and slower as a general response. I quickly drew my attention to 22ga and smaller wire for the next round of experiments. This round was bringing in a preconceved notion of my own that goes against vertually every cable design I researched. Almost without exception the only concept explored by manufacturers and DIY’s alike is twisting the wire around the core. My friends and I theorized that this allows the cable to be more flexable without fatuiging the wire. (like a spring) Spacing suggestions very, but almost without exception the cables are twisted. I used to own Nordost Valhalla cabling for about five years. The speaker cables are made up of forty very fine conductore that run parrallel to one another. This made me explore running my interconnect conductors parrallel as well. So in my next set of mock ups I tried variouse combinations of cable sizes and wire numbers either twisted or straight. Straight won every time! This was not subtle, it was very clearly less congested, and smoother sounding. The winding tended to make the sound feel constraned and mechanical. My personal explaination is wires running parallel on a two dimensional plane have only one chance to interact. Twisting around a core creates a three dimensional interaction and in sometimes many points of interaction. Someone once said, “keep it simple” and I think this advice fits pefrectly here. It also became clear that a single conductors in each direction was prefered every time over multiple conductors. (One conductor could be multiple stands bound as one conductor) The multiple conductor mock ups tended to be edgier or brighter, so I ended up focused on single conductor designs with 30ga or 28ga positive wires and 20ga to 24ga negitive as my prefered sound. I also determained I much prefered the cotton core to the Teflon.

SECOND MYTH EXPOSED: TEFLON SOUNDS BRIGHT! There has been quite a bit of discussion over the past couple years regarding the posibility that Teflon is adding a brightness, or a ringing to the sound of cables. This was bourn out in my mock ups to hold some validity; so next up was determaining what the best dielactric might be. I tried Teflon plumbers tape, cotton, paper, electrical tape and even wool on bare wire, teflon cased wire and enameled wire.. Again I tended to like the cotton, and it became even clearer that Teflon was an issue. Next step was to determain sheilding (if any) Now I know much has been talked up by manufacturers about sheilding, and I supose if you live next to a radio transmition tower… but if you look inside your components, wire is never sheilded, and these wires are running in, out and around transformers, power supplies and digital curcuits. I can not think of a harsher enviroment for EMI/RFI than this. So I must admit I entered this stage with serious reservations. I tried woven steel shielding, woven copper sheilding, copper foil wraps, aluminim foil wraps as well as some mock ups based on the Cardas Golden Ratio. Every one of these had some influence on the sound, but in my opinion always negitive. Shielding is a very dificult thing to do in a repeatable fashion for hand made cables, and I suspect one large area of cost for cable manufacturers. I ended up with no sheilding as my prefered direction.

Next up, two parallel wires run at different spacing. I decided on my own that even consistant spacing was important, so I tried a number of methods to build up a larger cotton core. This included multiple cotton ropes tied together, then in some cases covered in a cotton jacket with wire applied to that. Then another layer of cotton jacket… What a hassle, and clearly not repeatable. I did determain that their was a limit to spacing. Wires further than 7/8” apart began to lose cohenrency and naturalness to the sound. Less than 5/8” sounded brighter and more conjested. I settled on 3/4” spacing as the perfect compromise.

THIRD MYTH EXPOSED: INTERCONNECTS DO NOT NEED A CORE! I must be among the dumbest men on this world, luckly I have a lot of company. It finally hit me, interconnects can be flat. This was ground breaking for me. I’m sure everyone else already knew this, but hang in there, I’m a bit slow. I had purchased this 9mm (approx. 3/4” wide when layed flat) cotton sleeving from Audio Consulting. (Way too expenxsive) It comes as a flat sleeve, so I simply took my two wires, now in cotton jackets and sewed them into each folded edge of this tube. This was a sinple easy way to get a constant and repeatable 3/4” spacing for my wires. It also meant the least dieletric interface with material, leaving the majority of the dielectric as air. Air of course is the best dielectric, but bare wire hanging in space equidistant apart is hard to do, so given the makeup of cotton weave, it allows for about 90-95% air, with very little of the cotton even touching the wire. Perfect, NOT! Ever try to attach a cotton sleeve to an RCA connecter with two super fine wires holding it all together? The issue became painfully clear as I began breaking 30ga wire trying to devise a solution.

FOURTH MYTH EXPOSED: THE SCIENCE AND LOGIC OF A CABLE DESIGN IS OUT THE WINDOW THE MINUTE WE TRY TO MAKE THE CABLE INDISTRUCTABLE! Just take a moment and page through your favorite audio magazine and look at all the cables. Heavy outer jackets made from Kevlar, carbon fiber, Poly-something-man-made, indestructible Teflon uncoated… You get the point. Now look at the interface between this less than desirable dielectric jacket and the RCA. Heavy rubber shrink wrap as a minimum is used, often in layers. Air has a dielectric value of 1.0, Teflon is 2.0-2.3, (I know, they say 1.2 but I’m using a scientific table, not “what they say”) cotton is 1.3-1.4 and rubber is at best 3.0, Poly-something –want-a-cracker is 3.0-4.0 and so on. This means they claim to go through all this science and end up using some less than perfect materials because they need to, in order to make them stand up to us, the guys who pull out our interconnects by the wire. “OH YES YOU HAVE TOO, WE HAVE ALL DONE IT!” And yes, it makes sense that any manufacturer would build the product to withstand some abuse. So despite all the careful planning, the connector and wire interface is an issue.

I ended up trying a few designs; the one I settled on (if I felt the need to address this issue) was some very puffy cotton “piping” from a fabric store. (Thanks to my friends wife, I have not been in a fabric store before, there are some very interesting people hanging around in them) I used a ¾” rope cut in half (length wise) and put the flat cotton interconnect in-between the halves. I then wrapped a thread around the rope to hold it together. At the RCA I shrink-wrapped the last four inched of cotton rope to the RCA. This allowed for the rubber to remain as far from the wire as practical. It looks a bit goofy, but it’s remarkably strong. I did not feel the need to go to this extreme and instead pulled the 9mm cotton sleeve over the RCA and put a piece of electrical tape around it. Half the tape’s width hitting the RCA and half hit the cotton, I figured electrical tape was at least twenty times thinner than rubber shrink wrap, so it should have one-twentieth of the impact to the sound.

SO NOW WHAT? Well the design is complete, now I needed to determine the wire material and what RCA’s to use. For RCA plugs I tried Audio Note, Cardas, Connex, DH Labs, Eichmann, Monster, Neutrik, Radio Shack and WBT. There is not a great deal of difference between the Cardas, DH Labs, Neutrik, Monster and Radio Shack. The Audio Note and WBT were a bit more natural and certainly less congested, but in further testing I could not find a repeatable difference between Radio Shack’s $5.00 gold plug and WBT’s $70 connector. To my surprise the Eichmann was quite a step up. The sound opened up with clarity and speed not found in the others. (I should add that I used both the Silver Bullets and the standard copper connectors. I could not hear a significant difference between the $20 and $50 connectors) If anything I may prefer the copper, a bit more natural and not as bright. I guess it all makes sense that the Eichmann sounds different in that they are the only one with a different design. They use a pin for both the positive and the negative connection, so rather than a whole circle of signal connection on the negative it comes to single points. I assume this makes for a cleaner, more effortless signal transfer??? At any rate the Eichmann was my choice. I ended up with one set of silver and one copper out of default. If I had not already owned the silver I would have used copper for both sets of interconnects and saved a few bucks.

Selecting wire was a bit tricky, in that it can cost a lot of money and there are still a lot of variables. Rather than go through the entire process I will skip to the wire I settled on and hope you believe if it’s possible, I tried it! As a very quick overview I’ll make some general observations. Copper tends to be full, rich and makes for a nice neutral sound. Silver adds PRaT and dynamics not possible with copper. Silver also adds clarity and extension not possible with copper. Silver is also brighter, edgier and at times has an artificial tonality on the top end. Gold was the best of the copper and silver without the bright thin signature of silver, and the clarity was even better than the silver. I attempted to use silver on the negative run in order to keep the cost down, but the improvement between gold and silver is substantial, and worth the expense (my opinion) I did not try stranding silver and copper together nor did I try silver coated copper, (like Nordost) so there is plenty of room for experimentation in these areas.

I ended up using all gold wire, and because of cost I made some assumptions (meaning I did not try every combination possible) For the positive run I ended up using three strands of 99.99% pure 30ga gold wire (not twisted but loosely bound together in a 2mm cotton sleeve) and for the negative conductor I settled on one strand of 24ga 99.99% pure gold wire. How I concluded this set up was some trial and error and some faith on the articles I had read that fit my experience to this point. If I had the money I would have tried a cable using three 28ga for the positive run, I suspect this would be even better, but I used what I had already purchased (bulk purchases lower cost substantially) If someone want to buy me wire…

Much has been said about gold having a significantly lower conductance than silver and copper, but given the distance of one meter, it really is not an issue!!! Gold has a very low resistance as do the others, so my selection was based on sonic quality rather than scientific characteristics. The side benefit (but not my reason for choosing gold) is it does not tarnish and therefore sonically degrade like silver and copper.

Sonically gold was clearer, smoother, richer and more natural sounding than the other two. People have claimed gold is slow or too warm. Neither of these comments matches my experience. One reason for using 30ga was the pace it produced in my trials. This held true with the gold as I used it, and as I commented on in the paragraph above I suspect 28ga gold would continue to have excellent PRaT. I also suspect anything heavier would indeed tend to slow and warm beyond my goals. The interconnect I built is every bit as dynamic and fast as my Valhalla’s were, but with a much fuller and richer top end. I have not experienced the warmth issue either; in fact I believe the 28ga gold positive strands would be a possible improvement if it did add additional warmth. As of this writing I am still trying to determine if this is necessary, a bit more warmth would be welcome, but it might be too much if I tied to achieve this. Over the past two weeks I have spent over six hours every day enjoying music I have not pulled out in years. In ever case, I have no thoughts of what more to do or what is lacking. No fatigue at all and so musical! So altering this design might only degrade the success, but it might be better. Money would answer this…

SOOOOOOO you ask. How does it sound? Well thank you for asking, but as often with me, before we go there let me add a couple more comments.

As I said earlier, I owned the Nordost Valhalla cables for many years. Prior to settling on them I auditioned most every medium and high end cable made at the turn of the century. It is no exaggeration to say I became an expert on cables during a two year period of testing cables. I also learned there are a lot of cables being sold today that are inherently flawed sonically. Over the last six years the amounts of cables that have come to the market have increased many times over, and my personal experience has proven that most of these cables are no improvement over their predecessors. As the sonic quality has improved very little, the costs have climbed to an astonishing degree.

This is not to say that there are not some truly magical cables that have been developed. This topic has become the source of heated discussions on this site as well as Audio Asylum. I have heard so many people who call everything they do not agree with snake oil or an illusion. These people I have turned my back on for comments like this neither are mot worthy of answering nor correct. Cables make differences, and I have a very extensive background to back my claims. When I hear someone say they would never pay more than $100 on cables, I roll my eyes. When I hear people claim they can build a cable for $100 that matches the performance of, (fill in the brand) I get physically sick. These comments are made from people who either have very limited experience or a system that is not capable of appreciating what is possible. In fact this entire experiment began from comments like these. People claiming they can build a cable as good as (fill in the blank) are endless. Let me say hear and now, they are right. I too experienced the level of AudioQuest, Cardas, JPS Labs, Kimber Kable, Shunyata or any other brand you prefer. This is not too difficult, but is that the goal, to match the sonic quality of inferior or flawed cable designs? If that is the goal, I can offer any number of design options that will match that of the mass market cable companies. In fact if the goal is to match the performance of 90% of the cables available, then I suggest you can do this for $25.

My goal here, and in my discussions of this topic is to match or better the best Interconnects available. I have invested countless hours and money to build the best system I can afford and/or justify. I spend the time needed to fully understand the topics I discuss here and I offer my opinions to educate not brag or be the top dog. My ego is fine without this audio site, and therefore I enter this hobby for the enjoyment of music. I would hardly classify myself as an equipment junky or an ill informed audio nut.

My personal experience says that Nordost Valhalla’s are the quickest, most transparent cable made. The bass is so highly defined and the impact of the bass is beyond reproach. The downside of Valhalla is it tends to be thin and bright on the top end. My Reference cables today are Kubala-Sosna Emotion. These are the most natural and neutral cable in all frequencies that I have experienced. They are the best overall performer I have ever heard, the super black background, perfect extension and definition are beyond reproach, but they do not carry the slam and dynamics of the Nordost. A truly magical cable is the Purist Dominus line (both Rev B & C, with fluid or Ferox) of interconnects. The midrange and upper bass are so rich and believable they force you to overlook the lack of clarity on the top end and the lack of bass compared to the best in this area. These cables cast a three dimensionality to the soundstage like nothing I have experienced before.

I bring this up not as some have accused me of bragging, but to help you understand what I was attempting to match in this experiment. I wanted the speed, dynamics, bass and slam of the Valhalla along with the naturalness and blackness of the Emotions and the colour, hues and dimensionality brought out in the Dominus. My goal was to combine the three best I have owned. Along the way I discovered the formula for Valhalla’s detail and speed. I discovered a midrange equal to the Dominus and I found a naturalness of Kubala-Sosna but combining these attributes and then bettering it was not as easy.

So here’s the deal, and a source of disagreement with many at this site. People say:

“Cables do not make a difference.” This is wrong, naive and foolish and clearly not arguable in a logical discussion.

“Cable manufactures are overcharging for their cables.” Yes they are crazy expensive but I can not say they are over charging. My simple little cable takes hours to build, and if a guy is to market, travel, inventory, purchase the equipment needed to produce a repeatable product… then I’m not sure they are so inflated. Yes I agree it’s silly, but my design has about $655 in materials, (approx. $300 in 30ga wire, $285 in 24ga wire, $40 RCA’s and $30 in cotton sleeves) maybe eight hours, so what is that worth? If any comment is true it would be the low and mid priced cables is the scam. Charging a few hundred dollars for a $25 value is the rip off. The top end is closer to a bargain. So yes they are all pricy, buy not out of line if a business is expected to make a profit.

“People buy expensive cables to brag or whatever.” Give me a break; people buy expensive cables to improve the sound. Not everyone wants to do what I just did, and yet they deserve the best sound. It is not the consumer’s fault that it costs a lot, we continue to demand more from our systems, and the manufacturers continue to push the designs. It’s just a fact, cables cost money to build.

“You can get the same sound from a DIY cable at a fraction of the cost.” Absolutely correct, I have tried most every cable made over the years, and I can unequivocally state that in my experiments I would be willing to guess I matched most every cable made. That is not to say this is a good thing, but just that I too can build glare, brightness, poor imaging, bloated bass, slow methodical pace… I can also build bloom, warmth, blackness and silence, natural… I can build it all, good and bad, so? So what does that prove? Nothing to me. If I had not heard the Nordost Valhalla, and the Kubala-Sosna Emotion and The Purist Dominus I would have no way to judge what I was building. If all I had heard was a Cardas Golden Reference, then I guess I would be satisfied when I had duplicated it. It is not right to chastise those who continue to explore the possibilities just because someone thinks cables are too expensive.

We can not judge life without experience. How do you know you’re happy if you have never been sad? How can you judge success until you have failed? You can not, and it hold true in audio too. Without having heard most every cable made, I could not properly judge the results, and thus I could not have ended where I am. So for those who choose to pock the fire, fine, but it is you that is missing out, not me…

Enough soap-box, now let’s talk about the sound.

The sound is quite close to a perfect blend of the three best cables I know of. This design is stunningly fast, excellent slam, highly emotional, very full and rich, fully open and extended. The imaging is tight with great depth, dimensionality and soundstage. The background is more liquid and blacker than any cable I have experienced. The clarity is the best I have ever heard. There is a tonal richness that is hard to believe. Piano is tonally perfect although one of my local A’gon friends wants a bit more bloom around the notes. The colour and hue around all stringed instruments is so perfectly natural and portrays an endless palate of tones.

To this point I still had one complaint, the high frequencies although fully extended and extremely clean, had a slight haze remaining around the highest frequency notes. This haze was not apparent when compared to the other cables; it only became apparent when I tried one more component in my design. I used a Bybee Slipstream Purifier ($75 each) on the positive conductor at each RCA. (Four total or $300 on one pair of interconnects) When I compared the one with the Bybee vs. the one without the haze became apparent. When I added Bybee Slipstream Purifier to the second set of interconnects the top end remained extremely transparent but now without the slight edginess first sensed. The entire presentation took on yet another dimension of realism. This got me to the goal; I now have bettered every single aspect of my system, but all at once! The final produce costs me almost $1000 in materials.

So in the final analysis

As many of you know my health continues to be a problem and time is all I do have. Not only that, but as many also know I have been forced to keep down sizing my system repeatedly over the years. This experiment is successful enough that I will be selling my manufactured interconnects and will be able to pay a few more medical bills!!! As for speaker cables and power cords I do not believe it is as beneficial to build my own, at least right now. My lessons learned in this project do not apply to either the power cords or speaker cables, so it would take another extensive research and a lot more money. My next project is to research power conditioners. This is where I think the true robbery is taking place! So if you care to contact me about the interconnect project or my coming research I would be happy to share what I know

Below are links to some of the research and material suppliers I used. I hope this thread will help settle some of the controversy about cables, and possibly help some find a better cable than they ever dreamt of.

JD has kindly provided me with the following info on his experiments with Titanium conductors, and suggested I may want to post them:

"I received some titanium leads from a medical device manufacturer friend. We were discussing my DIY interconnects when the topic of his wire came up. He gave me a couple strands of what feel
to be about 28-30ga. In a nut shell the titanium was super hard to work with (very stiff) and it sounded harsh but extremely sharp focus. Not musical in the least, so I ended my
experimentation quite quickly."

I suspect that Titanium wire may still be best used for repairing intestinal hernias. . . ouch! G.
Thanks for all your efforts and your sharing of your experiences. I hope your health is better, too.

I have tried most major cables through the years and found that there is a way to get SOTA performance on the extreme cheap. It goes like this: Use single runs of Wonder Wire with a loose cotton sleeve (available on-line VERY cheaply compared to, say, RAM's stuff you mentioned-- which I have also used myself. Yes, very expensive-- but good), surround with extremely lightweight fluffy cotton (available at any fabric store) for proper spacing. Then, using copper foil (easily bendable but not so thin that it requires many, many multiple wrappings), create a tube that you slide the wire into (you can use a garden hose trimmed to proper length with the ends cut off as a form for easy slide-off/removal.) GENTLY bend the tube to fit your curvature required; you can use the hose as a form for this, too, if the bend angle isn't too extreme. ALWAYS ground the copper shield (or it will crush your high frequencies and close down the sound!) but make sure you don't ground out the cable's wires. Hardwire the ends if possible. If you don't want to hardwire (understandable), SwitchCraft used to make killer super-cheapo RCA terminations ($5/pr), but I don't know about that anymore. (Hardwiring is best, though.) Also, Vampire's Wire's stuff has been very commendable for the money ($28/pr), but Bullet Plugs are supposedly FAR superior. (Wouldn't know, myself.) Support the copper tubes with rubber bands if in the air, or if on the ground, use wood blocks cut to height from 2x4s and band-sawed to a fine triangular support point that minimizes mass near the contact area. No need for those expensive cable supports! (And no, I haven't tried different woods for the support blocks. If anyone has, I'm all ears about the difference. I just use that super cheap pine from Home Depot. Works fine to my ears!)

This is a really inexpensive set-up that will blow your socks off. A very similar design was created some years back by RWA Cables with braided and tinned copper mesh shielding, cotton insulator and annealed connection between RCA and wire. Very expensive due to the handicrafting necessary, but incredible performance. My design gets you to the same place, but for WAY less than $100 per pair as opposed to nearly $1000 for a two meter pair. (Still, the RWA's were excellent. But this was a few years ago. Have no idea if the company is even around anymore.) You can substitute wires (silver, copper, gold) as per your preference. You'll be shocked.

Buy the stuff (copper foil, cotton sleeves) on the net. Michael Percy Audio has the bare Wonder Wire for about a buck a foot, so $30 gets you a two meter pair of wires. As for current SOTA solders, no comment ( I use Wonder Solder that I bought a ton of from Mike Percy about a five years ago. If anyone is up on today's hot solder, again, I'm all ears.) Another $40 gets you a half mile of the cotton sleeving (seriously). The copper foil is a little more expensive (bought by the dimensions/weight), and $ minimums are normally required, but you get a ton of it that you can use in lots of applications, like DIY power cords (remember to ground your shields!) Or get the copper mesh braid from Michael Percy cut to exact length neeeded. You can always go in with other audiophiles and get a bunch of whatever you need. Make 'em for your friends, astound your enemies! You'll all be overjoyed with the results.

Happy listening!
ALWAYS ground the copper shield (or it will crush your high frequencies and close down the sound!) but make sure you don't ground out the cable's wires.
What's your suggestion here? Load side, connected to return wire, or...?
Cheers
This thread gets my vote as the Most Interesting Thread on Audiogon. I'd love to hear about your continued research JD, if health allows.

My best wishes to you, and thanks for all this brilliant research.
Hello Winston, Osgorth and of course my old friend Greg.

First off, I must thank you for your sincere concern for my health, and for the feeling within your words. I can not adequately express how important the love from my audio friends has been to me, and how much Audiogon has helped inspire me.

Since starting this thread exactly one year ago today my life has changed wholly because of Audiogon and the dear friends I have been fortunate enough to know. Audiogon is without question a perfect example of what is possible in this world if people simply take the time to be a positive part in others lives.

In answer to your question regarding my health, physically I experience more days with zero energy than I had before starting my business that was the result of this thread. As most know, I lost 80% of my heart function, now ten years have passed since they gave me a 5% chance of leaving the hospital and no chance of living beyond three years. That being said, I will be watching my last of three kids (Michael) graduate High School tomorrow night. This is a feat I never expected to participate in. Michael is disabled (CP) and requires 100% assistance, but is evidence of how little importance our bodies have on our lives. Michael has over seventy people who have requested tickets to the graduation ceremony; these are people who he has touched over his schooling. Michael is pure love and joy; I could have no better role model as I continue my personal journey. Last week I attended my daughters’ graduation (middle child) from collage. We are sending her off to Miami Friday, and again I feel so lucky to have been such a strong part of their lives.

My physical energy has suffered because I am continuing to share my love for this hobby with friends by now building them for sale only hear at Audiogon. This has been a true positive in my life however. My creative mind, nurtured by a very successful architectural career had become stagnate and was dying with every year that passed. My health just would not allow me to pursue my career, and I continue to struggle with the depression I suffer. But THIS, THIS wonderful hobby, THIS wonderful website and This wonderful thread have changed my mental outlook.

For the first time in ten years I am excited, I am alive and I simply can not stop my mind from creating. My creating is now in my head, brought about by my ears and delivered through my system. This has awakened a new spirit in me, and I am taking full advantage of every second of it. I am truly blessed; I have amazing friends on this website. Everyone who writes, either in interest of buying a cable or simply to say hi are my friends. I look at every email as an opportunity to gain a friend and share my love for this hobby and to share my life. Over the past seven months since starting this business I have gained friends in over thirty five countries on four continents.

This would not have been possible just ten years ago, but now I find how very small this world is. I have been invited into people’s lives, sharing this hobby, but more important sharing their lives. I hope I have been able to give back half of what I have gained, and maybe, just maybe helped to change a tinny part of the world. I try to share my love and my soul, and in exchange I receive their love in return. Our governments may try to dictate how we perceive one another, but as individuals our souls only recognize love. In a forum like this thread, we still can stand behind the protection of anonymity if we prefer. In emails, we are offered the opportunity to gain a friend, and maybe help change the perceptions our governments have created.

So the very long answer to my health is physically my cable building and experimenting is taking a toll, but mentally I am alive and my mind is in the creative mode I am happiest with.

This brings me to the second half of this post. I have continued to experiment and learn. I am sadly reluctant to post my thoughts in the forums regarding cables because I do not ever want to come across as one of “those” manufacturers who use the forums to self promote. There are a few who have been so blatant, and sometimes I am sure they even start the threads with a moniker that has never posted before, only to answer their own post. I despise this tactic, and I fear if I talk about what I have learned, I will appear to others as just another one of “them.” Therefore please if I ever do cross that line, write me and tell me, for I never want to become self promoting in the forums. I use my ads to promote, and have been trying to share what I am doing through the copy in the ads.

In this instance I will take a moment to share what I am doing, and what I have learned, for that however, please read the next post, this will keep the personal stuff from the information stuff.
