My list of tweaks and the verdict


As metro NY has been pretty much shut down for the past 11 months and counting, I get so bored sometimes that I find experimenting by buying tweaky audio products to be a helpful reprieve and keeps me from spiraling into the abyss.
So this is what I have purchased in the past 6 months and my quick verdict on sonic impact — what I hear or perceive to hear using my brain and ears in my 2 channel all analog all tube setup:

Not in any particular order and using baseball terms:

1. Walker Audio Talisman. Strikeout. A big swing and miss. The silliest purchase for sure.

2. Copper ankle socks. Home run. No more shocks when I touch my tonearm. Just wow. Least expensive tweak to date that works.

3. Symposium Segue amp shelves. Strikeout. Heard no difference in noise floor, bass, etc. But looks really nice.

4. Symposium Segue ISO Stealth turntable shelf with Rollerblocks Series 2. Home run. Out of the park. Really hear and SEE a significant improvement in everything - clarity, bass, soundstage. Took the performance of 2 very different turntables up a lot. “See” because my needle would jump sometimes and now you can actually see the rollerblocks doing their job swaying back and forth with no impact on the music like a building a Japan. Disclaimer: Room suffers from significant footfall.

5. Townshend Seismic Isolation Platform under my Harbeth 40.2 Ton Trager stands. Home Run. Further improvement due probably to serious footfall in my room. My most expensive tweak but worth it to me.

6. Stein Music Carbon Edition Perfect Interface. Another big swing and miss. Strikeout. Zero diff perceived vs no mat or stock mat. Most expensive swing and miss.

7. Yellow bird Hexmat. A solid double. First time I’ve heard a mat make a noticeable improvement. Probably cause this mat is a record isolator/decoupler and again reduces impact from vibrations.

8. Stillpoint Ultra LPI ver2. A solid double. This one is so easy to A/B and hear a noticeable improvement on some songs vs using no record weight or even the stock record weight. Basically things got quieter enabling me to turn up the volume which increased the perceived dynamics. Plus it looks really cool.

9. Symposium rollerblock jr. Under my phonostage or preamp. Strikeout. I don’t hear any impact on the noise floor but theoretically it’s there.

10. Isoacoustics Gaia tried under preamp, phonostage, amp. Strikeout. Didn’t hear anything noticeably different but again theoretically it’s doing something.

11. Assorted tube rolling. NOS, new new etc. Not sure if this is a tweak but I didn’t really hear any discernible difference to my memory. But it was fun to learn and do it.

Well there you have it! Anyone have similar experiences?

@lowtubes. 
Well that’s all fine and good. I do have audiophile high end EQ’ed hearing aids (that’s a whole other thread on here) and  I think my tubes were pretty good to begin with which may be why.  And the other issue is that there was a lot of time in between — the next day kinda thing.  
Wow, With the tube rolling you didn’t hear any difference? I question your hearing or your equipment or the tubes that you were rolling.
Hello to you Yes we all want that Magic tweek a lot of snake oil remember everybody wants to sell , as far as a isolation platform def a Home Run i hame made my own out of two 1inch birch wood very thin layer of cork between them and Vibrapod  x6 feet  for a total$ 40.00  i have also taken apart & cut up a few power cables  a lot of  nothing but smoke & mirroers it does not take Big Bucks to Put together a GREAT system   
@stringreen , watch the news first to get yourself really pissed off. Then if they sound better you are more likely to be onto something.
I just bought 2 Schumann generators ......I made sure they are returnable if needed....we'll hear.
@turnbowm- I said for ALL cables other than power, shorter is better. For power cords, it is better to have slack so there is no risk of them unplugging due to tension and getting them a few feet longer, nothing extreme. 
@mahgister- as you say - it helps in the right environment- for @redwoodaudio, the Schumann Generator did nothing to improve the sound for him. That’s all that matters. There is little that all agree on here on Audiogon. Measurable improvements are not always audible.
You have psychic abilities now too? You have no idea how my room sounds.
You are right i dont know HOW your room sound and i apologize ...

But the problem is not how your room sound, probably good, but how much it can be improved...

I dont understand why no audible effect were perceptible with the S.G in your room. ...

Except for the room ...

We are not the only one who tried S.G. most people who use them hear an audible effect....

Then my post is a deduction not and arrogant affirmation born from psychic abilities i dont have....And certainly not a rebuke of your truthful and direct experience...

We must not confuse the fact that a room may seems to sound "good" enough, without being at the same times at his best acoustical greatest potential at all ...

Most people confuse the 2 and try for decade costly upgrading of electronic design gear instead of improving the acoustic potential of their room....

This DEDUCTION was only my point.... Not arrogant psychic abilities i dont have...

I am perhaps faulty in this deduction but then why there is no audible effect in your room and there is effects in many owners of S.G. ? There is other possibilities than the room but i dont want to create useless arguments...

S.G. is not a new "tweak" in town waiting to be evaluated....It is a very well known fact in audiophile circle for decades and easy to verify in the right environment...

Anyway i apologize for the discomfort i have created with my post....

My best to you....


 P.S. This is the reason why i never recommend S.G.  in the first stage of room treatment.... The effect could be inaudible....
@mahgister 

You have certainly better things to do, i guess it will be improving your acoustic treatment and controls...This experience is a sign of a lack in your acoustic settings....

You have psychic abilities now too?  You have no idea how my room sounds.

"...I believe it cleans up the power as the current goes from the wall (or a power conditioner, power strip, etc.) to the component, so the longer the cable, the more it conditions the current..."

Theoretically, the longer power cord, with more inductance, capacitance and resistance, would provide more filtering but I think the difference would be minimal at best.

The downside to the longer power cord is an increase in the source impedance of the AC supply to the components with a resulting reduction in music dynamics (bass impact, in particular).

Companies like Audioquest and Shunyata Research go to great lengths to minimize the impedance in all of their power delivery components (power conditioners, power cables, etc.) for this very reason. This same consideration also applies to their speaker cable designs. Longer cables defeat their best efforts.
 
Tweaks for little money that work:

Wrapping DAC and Streamer in EFI/RFI cloth

Using Black Ravioli pads under source components

Using Caig Deoxit or similar on all signal and power contacts

Replacing spades or other high mass speaker cable terminations with crimp-on, low mass, brass crocodile bananas

The Cartridgeman Isolator between headshell and cartridge


A litlle more money:

Stein Speaker Match

EMO EN70-HD inserted in ethernet to streamer connection

Intona Isolator inserted in streamer to DAC connection

Furutech NCF Clear Line passive power conditioner

Acoustic Revive RUT1 passive USB conditioner

EAT and Duende Criatura tube rings


Expensive but worth it:

Bybee Golden Goddess speaker Bullets

Acoustic Revive Rem-8 and RGD-24 under source power transformers

Acoustic Revive RTP passive power conditioning bars

Gingko Audio isolation platforms

Symposium Svelte Shelf isolation platforms
And I tried a Schumann generator for a while, didn’t make an audible difference. I guess I could have tried 6 or 8, but I had better things to do.
The S.G. produce audible effects but in an already good room where the effect can be audible in the first place... The effect of my S.G. is very audible and subtle at the same time especially in higher frequencies range, no way i would have been able to enjoy them BEFORE my room increasing acoustical controls and treatment...There is an ORDER in the process of improving a room , the S.G. are NOT the first thing to do at all....

You have certainly better things to do, i guess it will be improving your acoustic treatment and controls...This experience is a sign of a lack in your acoustic settings....

My best to you....
@aj523 Thanks for the work and the tweak reporting.   I am sure it was a lot of work and I appreciate the effort.   Thanks for sharing.
Appreciate some reporting from the tweak trenches, OP. 
My favorite recent tweak: isoacoustics oreas under my harbeth 30.2s and tube preamp.
And I tried a Schumann generator for a while, didn't make an audible difference. I guess I could have tried 6 or 8, but I had better things to do. 
@turnbowm- I believe it cleans up the power as the current goes from the wall (or a power conditioner, power strip, etc.) to the component, so the longer the cable, the more it conditions the current. This was explained to me by a company that specializes in cables. They aren’t trying to sell longer ones as they also said to get the shortest interconnect possible.

Some consider a power conditioner a tweak, but I would say it is an essential component, and can be had for a relatively low investment, although you can spend thousands on them if you want. I don’t think that is necessary for typical home audio environments. Exceptionally high current ones could necessitate an expensive one.
sokogear317 posts02-15-2021 8:58am"The longer the power cord the better...These are indisputable scientific facts..."

Is there a scientific reason why longer power cords are better? If so, what is it?
@lancelock 

Those were my exact thoughts - how is this going to work.  It may just be the most perfect union of mat and record weight because the favorable impact on the sound was quite noticeable.  So the hexmat works as an isolator suspending the record off the platter to reduce vibration while the Stillpoint is doing its thing pressing the record down onto the mat to reduce vibration but only on the label obviously where there are no contact points.  The website for Hexmat mentions that record weights don’t negatively impact it’s performance.

@aj523,

How did the Stillpoints Ultra LPI ver2 work combined with the Hexmat?

Indisputable scientific facts ... Nothing like gross hyperbole for a Monday!   Longer power cords, but you better make sure those fuses are really low resistance ...

Please don' replace the metal case of your amplifier with a wood one. Just takes one good fault and poof, there goes the house. Electrical products are made of metal or certain plastics for a reason.


If your humidity is low enough that you are worried about static, but a humidifier. Static spray isn't going to help the lack of humidity in the air.


I am going to go with no human can reliably whether my cell phone is in the room or not, not because of the microphone at least. Carefully placed for a sound reflection perhaps, but I am not holding it by my ear like that.


The longer the power cord the better. The shorter the interconnect or speaker wire, the better. Don't let wires touch and keep them as still as possible. 

These are indisputable scientific facts. Minor violations will most likely not be audible, especially if you don't know something happened. But major things, like using long interconnects that probably require XLR cords/plugs or speaker wire will be.

Love to hear the jokers who make fun of the most extreme audiophiles whose listening rooms probably resemble Jimmy McGill's departed brother from Better Call Saul who was petrified of any magnetic or electric field. Tin foil, etc....

Remember - if you think it sounds better, it does. The mind is a powerful thing.
How about a list of cheap tweaks or no cost tweaks.
Here's some that I've used.

Plug components directly into AC outlets and avoid AC power strips.
Replace standard ac power cords with shorter cords that are of heavier gauged wire. 
Buy a large ball bearing and place it on you turntable to see if it is level.
Clean RCA connections by unplugging them then reattach.
Place a heavy weight (Iron dumbbell plate) on top of your solid state amp or,
Remove the cover of your amp and replace with a piece of glass or solid piece of wood.  

During the winter months spray the floor near your stereo with a mix of Water and fabric softener. I can't remember what the water to fabric softener ratio is - maybe someone can help with this. This reduces static electricity.

Remove all inactive speakers from the room. This includes cell phones, remotes with mic's, headphones, blue tooth speakers and any device that talks to you. A Linn dealer showed me this effect by removing a pair of headphones from a listening room and then reintroducing them into the room.

Lower the noise in your home by turning off the refrigerator, AC or heating system and other electric devices that emit noise.  Just remember you turned them off.

If you listen to your music through pc speakers and they are sitting on a glass table try putting a folded wash cloth in front of each speaker. 

Place your pc tower on three or four half tennis balls. Used tennis balls cut in half can also be used under stereo components but have varying effects. My stereo's sound improved when using a whole tennis balls because the stand and shelves were all metal. Three whole balls under components are very unsteady and you got to be careful when touching the component. It helped the amp, pre-amp and cd player. It also certified me as a complete audio nut when my friends saw this. Then they heard the difference and agreed but still laughed....a lot. Then I told them about a cheap $100.00 ac wire I was considering. That got a good laugh.

 Anyone have other tweaks to share? Please do so. I'd love to see what has worked for others.
Thanks
Depends on the CD player. Given CD drives worked fine at high speed in laptops slow speed in audio is child's play. All comes down to how the electronics derive their clock and how immune the DAC is to jitter.
@audio2design

Yeah so I’d say the biggest bang for the buck is clearly around turntables and speakers for sure.
The Townshend podium under my harbeths was a revelation albeit an expensive ticket for entry. The fact that vibration control works under those doesn’t necessarily mean it didnt or doesn’t work under other electronics like an amp, preamp. In fact I’d say it likely does but in my case perhaps my particular brand of amp or preamp doesnt benefit, or I just didn’t hear it cause it was so subtle and not perceptible to me. I don’t have another source in this setup to try like a CD player but I suspect it would be improved.

Now one thing I didn’t mention is that I have the entire rig running through an Audioquest Niagara 5000 power conditioner which was my first significant upgrade - going from 3 wall outlets to just one thru this unit improved the entire sonic presentation, background noise dropped to a crazy silence, all those proverbial buzzwords comes to mind. I didn’t view that as a tweak though so didn’t include it. That’s an easy one to experiment with and hear an improvement. 
The way I read the ops post, the products that actually do something, i.e. address vibration issues with a turntable setup make a noticable difference. The ones I would call tweaks, i.e. supposed vibrations in electronics, did nothing.

You know the biggest BS that many are susceptible to? The BS that says people who haven’t tried or heard know better and are entitled to second-guess those who have.

+10,000

And to the OP - Thanks for your refreshing and honest take your tweak attempts.
@aj523 I actually tried a 2nd Clear Line but just was too much so dealer took back. Although I tried it on my OLED TV and seemed to give me slightly better color but didn't think it was worth the 200.
Love the naysayers when they have never even gave it a shot.

Kinda like all those people who told Columbus he would sail off the edge of the earth. Or the ones that told Chuck Yeager his controls would reverse and he would die when he hit Mach 1.

Take your tinfoil hats and hold them between your knees.

Cheers naysayers.


@rsf507 
Very cool!  I have not taken it out of the system since I was done experimenting maybe 2-3 months ago. I guess I should!!  Btw when I told my dealer I wasn’t sure if I heard a difference or an improvement, he said buy another, but two more lol . Gotta love it 
@aj523 bought the Furutech Clear Line "things" at recommendation by dealer at just over $200. Best tweak in a long time. Not only blacker background but everything just sounded a bit more round and fuller. Thought initially in my mind but left it out for a few days then replaced and clearly a very nice improvement. 
There exist 3 working dimensions for any audio system:


-Mechanical : try and experiment with simple device to eliminate vibrations but also to decrease internal resonance in the box speakers ( other gear also but speakers are very important)

I succeed for peanuts with sandwich of varied materials under my gear and using springs in a way to decrease resonance with a dyssimetric compressing force applied to them.... Cost: peanuts...

-Electrical: Decreasing the noise floor of the house electrical grid is of the utmost importance.... I created my own device at peanuts costs...
"golden plate" : shungite plate+ copper tape on the external side....I put 30 of them all along my electrical grid.... Very audible impact... Low cost...

-Acoustical controls and treatment: I used passive materials treatment homemade with simple materials, absorbent one, reflecting one and diffusive devices, i use Helmholtz tubes and bottles, resonators, cheap grid of Schumann generators modified, and ionizers, and many other devices....i created my own room tuner at NO cost....The Helmholtz-Fibonacci room tuner....

Cost peanuts with result so powerful that it is better than upgrading with most possible choices in my purse range...


Is it snake oil?

Feel free to try my device or idea....I sell creativity, confidence in our own ears, and fun....

Is it hallucination?

I must say that i will feel insulted to read that about my experience especially on the guise of an alleged "scientific explanation"....





My advice is simple: dont buy costly cables and costly "tweaks" before  taking care at low cost of these 3 working dimensions where your audio system is working....I never bought "tweaks" and i dont need them now at all....

A tweak can  never  be a method of listening experiment and no tweak  can be the  single solution to all the problems is these 3 working dimensions....

Tweaks are costly and even if they work you can most of the times replace them with a no cost solution.... I did it then you can....
Thanks for all your thoughts @aj523. I 100% agree with the Townshend pods- I have their seismic platform and when I put it under my admittedly light turntable, it completely blew me away. Herbie’s mat got rid of my problem of the static from a stock felt Rega mat lifting off the table, but I didn’t really notice a sound difference. I also put Herbie’s Tenderfeet under my phono stage and amp, but didn’t notice anything, but I didn’t expect to.

I get no shocks when touching my tonearm, and Rega specifically says not to use record weights as it is completely diametrically opposed to their low weight philosophy, so I’ll wait to hear what happens with the Schumann Generators. I am always looking to improve the sound of my existing equipment. 
It would be nice to not hear comments about either only tweaking (electrically, mechanically and acoustically) or only getting new equipment to increase SQ. Anything may help - trust your ears, nobody else, least of all reviewers.

Can anyone please explain how Schumann generators work and what they are?
OMG I can’t believe I forgot two additional tweaks! Too bad you aren’t allowed to update at least the original post.
Anyway for those that are following my (mis)adventures, I bought

12. Cardas audio rca noise cap covers for my preamp. Can not tell any difference even putting them on and off as music is playing but they were inexpensive and I feel they are protective in some way so I kept them on.

13. Ok don’t laugh but I also bought the $249 Furetech Clear-line plug. Thinking reputable company, smart engineers and Jesus it comes up in all social media feeds so I said wtf. 
Anyway I tried it first in my dedicated outlet and then in my Niagara 5000 on an empty outlet which shares the same bank as the amp. Classic snake oil? Hmmm This one is tricky. I feel like it does make a difference on the noise floor but subtle at best and probably my brain playing tricks. I could have returned it but I didn’t. Anyone else try this one, the marketing of it is everywhere lately.
I sorta thought it was ear to brain. My point aj is that the equipment is where the money is not in these things. Most tweaks are only about improving the eye to brain experience.
This is completely false....

The S.Q. is where your creative work to rightfully install the gear is, in his working dimensions...My 500 bucks system is better to my ears than very, very costly system ....

Attacking blindfully all devices as "snake oil" is pure prejudices and ignorance...Some are, some are not...

My own devices cost nothing or almost nothing and are homemade and completely transformed my audio....Hallucinations?

Think before judging and recommending to people to throw money at upgrades ........The world is bigger and more surprizing than what consumerism dictate you to think it is....

It is more clever to learn how to control the mechanical electrical and acoustical dimensions than plugging new upgraded amplifier or new speakers....Acoustic of a room for example can KILL or TRANSFORM totally a pair of good speakers at ANY price....

And i am tired to read about "hallucinations" and "suggestion" coming from some about all other people experiences...

Sorry....

Nevertheless, i dont want to upset you....I only want to say what i think is true in the sea of your free generalizations to justify your prejudice.... And your prejudice is only simple: buy an EQ. and call the rest "snake oil"...

The best example is your last use of Bell curve without knowing what it is and how it is used voluntarily or not to hide reality....Same thing for your use of the placebo concept....

Negating the sensory experience of others and throwing all testimonies in the drawer of illusion and deception can be insulting, even if you dont want to insult people.... Do you understand that at least?

Invoking true scientific concepts like, placebo concept,  in a context that suit you, audio experience, to use them for your own opinion expression which is the negation of sense experience you dont want to hear about, is no science it is sophistry....


Right ear to brain. It was a bad joke. Anyway since I have little interest in claiming what I have is the best or that any audio tweak that I spent money on must work, it simply comes down to what I’m hearing and if i think it sounds better than it doesn’t really matter if it’s real or some false perception. It’s only my sensory experience that matters here.
For the record clamp I had my son take the Stillpoint record clamp and the stock clamp which is about half the weight and I had him stand at the turntable and switch between them and none at all and it was really cool hearing when the music sounded best to me. He heard it too but he had knowledge I didn’t, although I didn’t tell him one cost like 5x the other lol. Anyway it was harder to replicate that with the Uber expensive Stein mat but I tried and for the life of me couldn’t hear a difference between it and no mat. Doesn’t mean it’s not there I just couldn’t hear it. But that hexmat wow but perhaps with a SOTA I wouldn’t have heard such a stark improvement in either the clamp or the mat.   Lots of fun regardless.
@aj523,  

"on improving the hifi “brain to ear” experience in my existing audio" 

 I sorta thought it was ear to brain. My point aj is that the equipment is where the money is not in these things. Most tweaks are only about improving the eye to brain experience. I think audiophiles would save a lot of money if they were blind, not that I would wish that on anyone.
If I take two identical cables and just put a fancy jacket on one and jack the asking price many people are going to think the jacketed cable sounds better. I admire your experimental attitude and if you can afford it, experience is the best teacher. The hard part is knowing your own weaknesses and keeping them from biasing the results. 
I bought a Nobsound record clamp once. It was very disappointing.
I just bought 4 of the Nobsound branded Schumann generators from Amazon so I’ll get them Tuesday and they are returnable if they don’t work for me.    
Thanks mijostyn but this thread isn’t really about my component choices but just my experience with various types of audio tweaks over the past few months and their impact, if any, on improving the hifi “brain to ear” experience in my existing audio room; being as objective and transparent as humanly possible. 

Cheers :)
@dwhess, I hate to be a stick in the mud but power cords and cables do not break-in. Mechanical devices do and perhaps tubes. Many manufacturers support the break-in myth because going against audiophile lore costs them business. The myth is an illusion caused by our central nervous system's ability to accommodate to various stimuli.
A good example is your cologne. When you put it on the smell initially is quite strong but after a while you do not smell it at all. Did it wear off? Not at all. You walk into the office and your secretary holds her nose. You simply accommodated to the smell. I remember walking into the coroner's "office" in Miami while he was doing a post on a decomposing body. The stench was overwhelming. I almost lost it before getting a mask laced with mint oil. The coroner laughed. He had no mask on at all. He was use to it. He called us "pansy a--ed medical students. Up against the ceiling he had a shelf that went around the entire room with his collection of smashed up and bloody motorcycle helmets. His suicide lecture was a favorite. He gave us a slide show of people who had blown their heads off. Quite a guy.  
Aj, a properly designed turntable with a proper suspension will TOTALLY ignore foot falls. You can hit a SOTA with a hammer and it won't care. Jumping jacks? No problem. SME's and Basis turntables will also ignore foot falls but you can not hit them with a hammer. Check out the Sota Cosmos Vacuum. It has vacuum clamping, a magnetic thrust bearing, a top motor management system and a hinged dust cover that will not alter sound when down. All this for 1/3rd the price of an SME 30/2.
1) Iso Acoustics Orea insulators under my receiver seemed to help the sound considerably. 
2) Iso Acoustic Gaia III under my speakers didn't seem to change the sound from the previous spikes.
3) Audioquest Type 5 speaker cables didn't seem to do much.
4) Voodoo power cord didn't seem to do much. 
 ***Although, all tweaks together did give me better sound overall and I'm still in the break-in period on the cables and power cord. 
You forgot the tinfoil hat, cuts down on both RFI and EMF...i don’t always listen to my stereo, but when I do, I wear my tinfoil hat. I saved money and made it myself. Don’t knock it unless you’ve tried it! 😉

Oh, almost forgot, my wife had some extra yarn lying around, so I used it to raise my speaker cables off the floor. You see, I tied one end to speaker cables and attached other end to thumb tacks in the ceiling! I actually think it looks nice, except you need to be mindful they are there, or you will inadvertently strangle yourself in a dimly lit room!

Wait, one last one...I place a large pitcher of water on coffee table in front of my listening position. I swear by this, as I do believe it is somehow absorbing the standing waves in that area of My room.
2.  Copper ankle socks. I can not for the life of me believe that another human acknowledged the power of this. Uncanny!
mahgister.....send a link
About what? i speak about many things....

I have a thread about all my devices....Feel free to read....

If you have a question i will try to answewr if i can....

My best to you....
But I’ll definitely check out Schumann generators looks interesting! Thanks again !!
Check my schumann generators grid modified with "golden plate" and my last creation using cheap chinese ionizer to smooth the room...

Peanuts cost and powerful results....



For the springs i use them but they must be used with 2 set of 4 for each speaker one set under and the other set on top under the heavy damping load.... The speakers must be damped by an heavy load (around 75lbs) to create a dyssimetric compressive force between the 2 sets to decrease the internal resonance of the rectangular speakers box....If not the musical timbre perception is unnatural....In my experience one set of spring under speakers is NOT  the good way...

My best to you....
