In Reply to: current "best practice" on footers/isolation for cd transport? posted by Chuck on March 27, 2007 at 11:19:16:
"I've been messing with the footers on my Vecteur D-2 transport and am reminded again of how important this variable is, which leads me to ask: what are now the "best" footers for digital transports?"It is difficult to say that there is one "best" solution as each system will be different but in my system, I found that employing the Walker Audio Valid Points Super Tuning kit to the CD player made a tremendous improvement in all aspects of CD playback.
The Walker kit, in addition to an air isolation base, and a Walker Audio precision motor controller supplying power to the CD player, has made CD playback most pleasing natural without one bit of the "digital nasties" ascociated with CD playback.
IME, isolating any digital gear from the rest of the AC world, either by a power regenerator or a balanced isolation transformer, is the best upgrade one can do to digital playback.

"Seriously? I've never thought to try that. What prompted you to try it?"I bought it for my VPI Scout and then shelved the TT due to frustration issues....long story.
Since the WAPMC was just sitting there, I called Lloyd Walker and asked him if it would be OK to power a CD player from it and he said "yes as long as it draws no more than 25 watts.".
Since the WAPMC has an input tranny, a sinewave regenerator and then an output tranny, anything plugged into it is completely isolated from the outside world. One can even switch between 60hz and 81hz with adjustment pots for each. Found my CD player sounds MUCH better at 81.14hz with the motor phase control reversed.
Have been running my CD player thru the WAPMC for about 7 months now with no issues at all and it sounds frickin' killer! So much so that I don't even think about vinyl much any more :-)
Cheers,
Thanks for the details.I was aware that the unit has an input tranny, a sinewave regenerator
and then an output tranny, and when a TT was plugged into it it was
completely isolated from the outside world. I learned that when I was
reviewing the piece and noticed that my digital playack improved when
the unit when regulating my turntable. In my closing remarks, I wrote:"Same difference. Almost exactly. But wait, there's more. Order now
and you (may) also get incredible digital playback! I did.??#^*@?? Okay, we all recognize that cleaning up noise in the digital
domain is a useful thing. Now we also know that cleaning up the power
to a motor on a turntable can produce results far beyond what one
might expect. But? But! I found myself fretting. How was it that this
PMC, designed for turntables, made my digital playback sound better? I
was consistently experiencing similar returns in dynamic nuance,
transparency, staging, improved pitch definition and extension in the
bass - plus just plain naturalness when listening -- believe it or
don't -- to cee dees.
Since living in Washington didn't create enough motivational energy to
road-bike my way to Walker's place in Pennsylvania, I elected to surf
over to his web site. He musta seen me coming, because, lo and behold,
he had already attended to the matter - in a manner of speaking. He
sez the PMC 'also prevents electrical noise from the AC drive motor of
the turntable from contaminating the AC power supply of your other
components.'"I just never thought to try it on the CDP itself. Good for you!
