Power cord suggestion for Plinius 8200?

I would suggest trying the Tara Labs Prime AC cable. It really helps clean up the sound and bring out the body and low end. It's worked wonders on every amp I've tried it on and is fairly moderately priced at $395 for a 6ft length.

I have this amp and think it's a big step up from the Krell KAV300i. I use the Sidewinder Gold, it's great match.

I am using a Shunyata Black Mamba with my Plinius 8150. Very pleased. Joel
