Try this simple DIY interconnect cable.
I know only that he recommended 12 AWG stranded wire. In the designs I have made I used 13 or 11 AWG stranded wire(had them available, no other "special" reason). You might, as well, use some shilded cable for the ground wire(as I've done in some designs). Connect the shield only at one end with the shield of the "main" Cable. I can't specifically tell you what (soundwise) is the difference between Shilded and non shielded ground wire as I haven't use them on the same designs. There are some other recipes that I found work very good. Go to the www.tnt-audio.com website and search for the TNT TTS(The Twisted Snake) DIY mains cable. It's a "must try" if you're in DIY! I realy have made many different cables but like them very much in my current setup. I could not find "the" recommended cable, but made them of similar cables. It's the design that counts the most, I believe. By my experience cables with several smaller AWG conductors "sound" better then a similar/same construction with only two or three bigger AWG wires! The latest, and I'm afraid best(in my current setup), design I have made 2 days ago... I've been reading about the Virtual Dynamics power cables on another forum (and their website) and wanted to give a try to something as close to them as i could get. I used 7 AWG(!!!!) solid core cables, shielded them (so I got an "coaxial" cabel) for the positive and negative wire. For the ground wire i used a simple stranded 11 AWG wire. No twisting. It's a dinossaur of a cable! I don't have to tell you how difficult it was to terminate this "cable"! It's stiff as...I don't know what to compare with. And It's a pain in the ass connecting it... But when finaly done this task I was surprised with the result! Even not "burned in" yet it sounds amazing! I've never heard such a "complete" cabel! Dynamics, soundstaging, you name it - sound amazingly effortless and lifelike! I forgot to mention I "put" them onto my CD Player. Immagine - this AWG wires for "only" a CD player!!! But it's to unpractical to use. I will try to make some smaller AWG (10 or 11) cables to make them a little more user friendly. Best Regards, David. |
Here are some photos of a similar design: photos |
According to Walt Jung and Richard Marsh, solid core 20 gauge is linear out to 20 KHz. Above that point, one may begin to experience skin effect. This will vary with the shape of the conductor though, so some conductors may be better suited than others. Wide and flat solid conductors with rounded edges will work best but then you have to start worrying about high capacitance as you bring the conductors closer together. While high capacitance isn't a big deal for speaker cables, it is for an interconnect. Goertz finally realized this and came out with their Micro-Purl series of interconnects after already having their "wide, flat & stacked" interconnects. While the Micro-Purls still use flat, wide conductors stacked on top of each other and twisted, they made one very important change. They inserted another unused flat ribbon between the two active conductors. This raises the inductance / lowers the capacitance and makes the cable more usable universally. On top of this, the same cable can be used in a balanced mode now, as you have three conductors at your disposal rather than just two. Too bad they didn't put the Micro-Purls into a better dielectric, as they might have had a real winner with this design. In the same article mentioned above, Jung and Marsh stated that their tests showed that the use of multiple 24 gauge solid core wires in parallel was the best way to go. This offered low series resistance with no phase or skin effect problems in or directly above the audible range. My experience is that this type of design works VERY well. That is, so long as one uses good quality materials and pays attention to the electrical characteristics of the cable. In my experience, using just one conductor of this or smaller gauge typically results in a noticeably lean tonal balance. The end result of using multiple wires of light gauge in parallel is a far more even tonal balance without intruding on the high frequency performance that the smaller gauge originally offers. Magnan is the company that uses conductive paint for some of their interconnects. The drawback to this is that it has a very high series resistance, which in my opinion and experience, is not good thing to design into a cable of any type. Some of the other Magnan's that i have make use of 36 gauge solid core conductors. As a general rule, you'll find that higher grade interconnects avoid using stranded wire. While one can use stranded wire, problems with skin effect and strand jumping will become more apparent at a much lower frequency. Sean > PS... As i've mentioned before, don't shoot me if you disagree with what i've posted. I'm only the messenger. Take your beef up with Marsh & Jung. |
