Has anyone tried the Shunyata Diamondback PC?

Grant,

You and so many other manufacturers are simply missing the point that, just because something is expensive to manufacture, doesn't necessarily make it _materially_ BETTER. Better constructed perhaps, but not necessarily with audible effect - this is what 'materially' refers to. Otherwise, take it as a challenge to provide measurements. I use your Sidewinder CXs in my Spectral system which offer absolutely no improvement over the stock, UL listed, power cord, and simply bought them for looks. Perhaps that stock PC was of very good quality???

Moving on to the Helix construction which allegedly reduces induction-based resistance - perhaps this is applicable to signal cables, but when applied to power cords, it does nothing to improve on the induction-based resistance of miles worth of average-quality wire leading up to our homes. Again, take it as a challenge to *prove* me wrong (not just *claim*).

Grant,

if you want to drag Spectral into this conversation I suggest you first learn how to spell Rick's last name. Every time a manufacturer gets into these discussions all they end up doing is offering more of the same - nothing; the end result is that you drag your own company down with unsubstantiated claims. So I eagerly await your test results.

Your last abbreviation, "YMMV", is exactly what I expect manufacturers to respond with. Some hear differences and others don't, and I am glad you do. In my case, I even used a Sidewinder CX directly to one of the Spectral amps, and the stock cord to the other - no difference whatsoever, even when playing mono material. From this I conclude the stock power cord is just as good as the Shunyata for *this* particular application.

I am very eager to see what Shunyata has to publish in terms of tests which will hopefully show that reducing induction-based resistance (as per Helix patent) in the last 6ft of a power cord has any benefit. Perhaps this geometry can reduce line noise, and since my MIT power conditioners already achieve that, the benefit isn't there for me???

Finally, I took it as a challenge to myself to verify that "Almost all Spectral dealers world wide also sell our power products together with Spectral" as Grant claimed. Results: two out of the total four in the US don't carry Shunyata (Music Lovers and Innovative Audio). Of the total 10 international Spectral distributors, 7 (seven!) did not carry Shunyata either. You can compare for yourselves at http://www.spectralaudio.com/dealers.htm and http://www.shunyata.com/Content/about-worlddist.html

Mr Grant - your credibility is very shaken with me.

Looking forward to it. I hope you won't neglect to describe WHY these improvements are relevant and significant (read: material) when applied to a power cord, not just that your cables measure better than others.

Said differently, why is better impulse current efficiency and lowered resistance significant in various applications (amps, preamps, phonos, et al), when the wires leading up to our outlets are presumably much worse when it comes to those electrical characteristics (and perhaps lots of others) than Shunyata wiring.

Finally, I accept upfront that some power cords can at least lower and/or reject noise (and I have measured my shielded Siltechs to do so, as also evident by the reduced hum in my phono section) - something I have not seen you (or your web site) discuss with respect to your products, so hopefully your document will discuss what Shunyatas have to offer in this respect as well.
