power cables' effect on power conditioner?

Easiest way to find out is to try various combinations.And yes a conditioner may change how the cords sound at various locations.And one size fits all may work, it may not work out well. I have all the same powercords. But that is because they were relatively cheap.If only I had a few others, I could compare.So not having all the same may or may not be an advantage.

Plus one for steakster. Try different cables, but high current capability is important for this application.

My experience is that the power cord to the conditioner has been my most important cord, bringing the greatest overall impact for my system's sound. This has been true with quite a variety of conditioners:  early Shunyata Hydra 8, Audience AR6, Audiodharma PowerWing, Weizhi PR-6, HB Cable Designs Acrylic and Marble units.  IME it seems that every component benefits from the qualities of that first cable (and I also agree that the power cords from conditioner to components matter a fair bit, too).
I am using a PS Audio P-10 regenerator now, and this is the first conditioner that doesn't seem to improve with some of my better power cords (e.g. going from an Elrod Statement to a Statement Gold, to a Diamond MB X2 made no difference to my ears).  However, going from a stock cord to the Elrod Statement was a nice improvement.  In all of the other above listed conditioners each cable move up was rewarding and worthwhile IME.

@lak. What was your experience with the 2Q?

@ptss, I like the 2Q very much and it does a very good job. Talking apples to apples in my opinion it functions better (sounds better) than my 1800, but of course its much better build, extreamly heavy but cost signifently more.
