Opinions: PC's with strong lows roll off the highs

Tvad,
I am using Audience powerChord on the amp. It's been resident on it for a while now, about a year or so.
Volex works good on the Pass amp, but Audience and Shunyata Taipan are better, although I moved the Taipan Helix to my preamp because there it sounds best in my system with the current combination of cables I have. Although the difference between Volex, SHunyata Taipan Helix Alpha and Audience powerChord on the amp isn't all that big at all, still, the Audience and Shunyata sound just a tad better, more natural I'd say, especially in the upper mids and treble. But as I mentioned before, the diff isn't probably worth the money. I already had all the cords, so I was able to find the optimum place for each, but yes, on the Pass Labs amplifier, the cord isn't that major of a deal. If the Volex works for you, keep using it, because the improvement you will get with a cord costing 100 times as much as the Volex will be a questionable improvement, in terms of whether or not you'll get your money's worth in sonic gains. Not so much credit to the Volex for being a great power cord, as to the amplifier design. Pass Labs did a good job. Now finally we don't have to spend a fortune on a power cord for a component in order for it to sound the way it's supposed to. I am happy with the Audience powerChord on the amp, that I purchased used right here on Audiogon, although if I didn't have these power cords on hand at the time, I'd probably be happy with the Volex on the amp as well.

Grant,
For $30.00 you might consider this pure copper cord:

Give it a few days to adjust to your amp. You might be pleasantly surprised as it has both body and smooth highs.

Audphile1 and Sherod, thanks for your suggestions. However, Tvad (Grant) isn't the one seeking recommendations on power cords. That would be me. Grant did post earlier in this thread the suggestion of a Purist Dominus cord. To his credit, he has quite a bit of experience with a variety of PC's. Audphile1, as far as the suggestion of the Audience and Volex cords, I've had both in my previous systems, and at their price I think they are great value performers. Sherod, I would have to say that Parasound's recommendation of a 12 gauge cord for their high power amp is a bit of a surprise. I have felt for a while now, that a thicker heavier gauge pc (10 gauge at least) would be the most appropriate for high current applications like the HCA 3500.

Foster_9,
Sorry for drifting off your initial request. I also wondered about Parasound's use of a 12 gauge power cord for their high-current amps. Surely they thought about this when researching cords. It wasn't so long ago, before after-market cords came onto the scene, that manufacturers had 12 gauge or higher hard-wired into their amps. There are a lot of threads on recommended gauge of power cords for high-current application. There are many variables involved.
