Hi Russ!!,Leads for Litz wire on the cheap??!..... Russ, I don't know what to tell you.
I was sent some old Monster / Brisson speaker wire, multi stranded, shallow angles, but it was slightly corroded internally and I did not care for it. The Monster wire was paralleled BTW, with 30 gauge CCC magnet wire. Next I tried expensive 12 gauge stranded pure silver wire - with the same 30 gauge continuous cast copper magnet wire in parallel. After break in, I liked the silver 12 gauge, until one day I paralleled some clip leads across it, went back and forth with and without the clip leads added, on the same cuts at the same volume level, and decided even more wire (than my particular silver 12 gauge) was needed to keep fully-intact the music's dynamic expressions.
In my most recent attempt, I've used Fulton Brown speaker wire, which is about a 10 gauge, multi strand, plated copper with shallow angles and tight bundling, and the same 30 gauge CCC magnet wire in paralllel.
THAT particular 10 gauge / 30 gauge combo was way-cool, 'gave me uncompressed dynamic experession on musical peaks, such as struck piano notes, etc, along with other nice cues relating to my speaker's dynamic resolution ...on ALL sorts of musical material.
I was listening to an early JBL D123 on an open baffle, with NO crossover components between the amp's output and the speaker's voice coil, and so, at 98 dB efficiency, I was able to "hear it all" very easily. The D-123 EXCELLS in transient response BTW, especially if you have good equipment powering it that does likewise.
No Russ, I don't have two of the same amplifier units to go back and forth with. But with the clip leads, EASILY added or subtracted to the existing B+ distribution wire, it allowed me to go back and forth in a controlled manner and listen to the effect of additional wire in key places. I really do trust what I heard Russ. It wasn't ever close, one way versus the other.
It was surprising to me - how much of a difference was made on my Rk self-bias resistor on the 6BQ5 output stage, when I replaced the Rk's solid wire leads with three ( and then four ) strands of Kimber TCSS. Of course, much of the amp's other wiring points was already optimized, so I could easily find the remaining weak points in wiring execution.
"They" always say, "keep the Rk self-bias resistor wiring on the output stage's ground return short", and NOW, I say, ALSO use about three or four runs of TCSS, right off the R's body, to conduct the audio signal wide-band and without information loss to ground.
As previously mentioned, I may build a 2 stage Loftin-White style DC coupled P-P amp in my old ARC D-75 chassis, using all these newer techniques. A single 6SL7 DCed into P-P 2A3s, two 5U4GB rectifiers and four 10 ohm low HY power supply Ls. The Fulton Brown speaker wire is no longer available. Dennis Fraker routinely uses expensive Siltec Silver inside his S.E. amps and attenuators, and discusses wire gauge and type, on his new Serious Stereo web site, go see that Russ.

This post is unbelievably bogus . There is not one crumb of real analytical evidence to support the claims being made here for this treatment of amplifiers. This is just snobbish, elitist BS taken to the extreme.
To nastily criticise me? This is the fourth time I've asked - and you do not answer.Tell us all YOUR audio credentials, so we can make some sense of the "reviewer" of my every post.
What sorts of systems do you have and have had in the past? How many years have you spent heavily into hi fidelity, and notice I said high fidelity, NOT electrical engineering. What sort of music collection do you have at home? When was the last time you heard live unamplified music??
What is your adjenda, mine is to further the audio art.
"Scientific proof" is not a prerequisite for posting up here Bubbah.
> "Scientific proof" is not a prerequisite for postingBut it certainly is a prerequisite to credibility, particularly when one makes these sorts of outlandish statements. Your time would be better spent demonstrating that someone besides you can hear these lightyear improvements. Until then, you can expect the community to continue to take you to task for this snobbery. And make no mistake, it IS snobbery.
regardless of the doctors 'bedside manor',i know for a fact , that he can, Hear.
take what he says, (what anyone says),
with a grain of salt.
Ah, I just said above that I heard it. Go back and read that please.
