component where PC does not make a difference

Has anyone ever had a component whose sound did not change significantly (or at all) with changes in power cords? I have found that different power cords don't really affect the sound of my amp (ARC VS60), but differences among those same power cords are revealed when hooking them to my DAC (ARC DAC7). Is that representative of tube amps in general or perhaps just this component? Would you expect that the differing "sonic traits" of various power cords would be better revealed on a DAC than a (tube) amp?

That is interesting. My VS60 is very sensitive to the power cable. Currently using Shunyata. Sounds way better than the stock cable. I am considering upgrading to Oyaide as I really like them.

Has anyone tried upgrading the PC on their Subwoofer. Wondering what the results were...Im running an SVS PC 13 Ultra right now...I use Black Sands Violet II PC's in the rest of my system...

My sub responds quite well with different PC's. Some good and some not so good.

I have never experienced a zero improvement factor upon introducing a quality aftermarket PC..I suppose the least rewarding improvement was on my pre-amp that has it's own dedicated Power Supply...But even in this case their was still a worthwhile overall benefit.

yes, the power cord going to my AC regenerator does not make any diff in the system's overall sonics.

This makes sense to me since the incoming power (via the hi-end PC) is completely regenerated so any sonic benefits from the incoming power cord are lost when the power is cleaned, massaged and re-amplified.
I am sorry guys, I have to retract/eat my statement that power cords to the AC regenerator do not make a diff. They do! I was full of it when I wrote that post! ;(
When I did some research as to how AC regenerators work I came to conclusion that AC power cords do make a diff + I actually do have a good power cord connected to my PS300.
