from lalitk "I would look into Zavfino and Audio Envy brands". I respectfully disagree, at least in part. I have never owned or listened to Zavfino wires, but I purchased two AE power chords at a show.
They were really cheap, so I figured what the heck. After a break-in of 50+ hours, they STILL SOUNDED WORSE than the plain-black OEM power chords that came with my Pre-Amp and Amp (both Ayre). Undeterred, I switched to the Anti-cable Level 3 - finally heard how a good power chord can improve Sound Q.
I now own four of the A-C Level 3 power chords. The AE power chords are still in a box in my garage: I tried to give them away on AG, but no takers - I think that speaks volumes.
P.S. I have no affiliation with either vendor.
