Can someone explain how power cords help if...

Sean:
It certainly is refreshing to hear a voice that listens
first to theory and engineering, and sometime FAR later
listens to the marketing rhetoric.
Good to see you back on AG.

Dats right,

Had ta kickit low style in tha hizzie cause some haters were tryin ta get my chedder cause they be spottin my dope kicks and be frontin like they are down with tha thug love in da west si-ee-dah.
So my peeps hollared out a niz-ine and spotted up dat follio's ride while droppin da capshells.
In da end tho hatas be gettin dissed, i be gettin missed, homegirl is already pissed, cause some hoochie thought she could play a playa by mackin my dogs chuggy.

So im back in the swing of things now and look forwared to working on my stereo system.

Peace :)

Sean,
Thanks for your post. For some reason, however, my Bryston 7 BSST sounded a bit more "dynamic" and "fuller" (best I could come up with, sorry) when I replaced the stock chords with the more substantial JP Cables Maximum Gold models.
I don't think it was purely emotional because I switched back-and-forth over a period of a month. (Maybe it's that voodoo business that's going around.)

I have enjoyed your posts on this subject (and others) and learned a great deal.

Thanks for the kind words. Believe me, i had a helluva time "staying away" from Agon. I still don't like the way that some things are being handled, but as i myself mentioned before, it is their site to do with as they please. Love it or leave it and evidently, i love it more than i want to leave. Besides that, i'm tired of arguing with people at AA and would rather just share ideas : )

As to Vvrinc's comments, i don't know if Bryston uses the same exact design / lay-out for all of their various models / power supplies or not. On top of that, it is possible that you were experiencing voltage sag with the stock cord that you weren't with the heavier aftermarket cord. I do not know the specifics of the stock Bryston cord and the aftermarket cord that you used, but this could account for a few things. Since the sags would primarily take place on transient bursts or long duration, high current demand passages, the dynamic contrasts of the amp would be the most likely to demonstrate such a problem.

Having said that, bare in mind that wire gauge is not all there is to building a "good" power cord. Obviously, voltage sag is one aspect that is measureable but my personal thoughts are that there are a lot of other factors at play here. Starting off with a heavy gauge cord that is of a low inductance design will get you most of what you are looking for in a power cord. If you can find those attributes at a reasonable price, go for it. Chances are, you won't be sorry and it will be a step up from a stock cord. Sean

Hi Sean. I too find AA difficult...as well unnavigable at best. Just wanted to chime in with my firmly-held belief that very-low dielectric involvement insulation (DISCLAIMER: like the Teflons used in my DIY PC Kits) is in most instances more important than huge amonts of copper, except of course in kilowatt monos.
Indeed power supply design is always the overriding factor. Yet even in (supposedly) highly-sophisticated supplies one can hear improvements in upper octaves transparency and staging depth when changing to a PC with superior insulation. Air and/or Teflon are simply better than cheap plastics/rubber/cotton, etc. By this statement I do NOT mean to condone the current over-spending for PCs, as you probably know, as PCs of the best materials should still be VERY affordable, after all.
