What is the best power cord for pass labs xa100.5?

No matter what Powercord will be used, all of them have upgrade plugs. The Plugs have in general an improved contact area and I think, this is one of the real advantages. You can try those with the existing Power Cord and I think, you will get an improvement, too. I bought those from Oyaide, internally they are really good. I use some of their Tunami cords, they are a real serious solution (technically and from the material inside), shielded and safe.

I agree with increasing the contact area, the main issue I see on 15amp iec sockets is they are loose, even the audiophile types. I always replace these with either 20amp with their increased contact area and much tighter fit or hardwire straight into the equipment. The Tsunami in my system sounded very beautiful tonally, but the sound was very slow and slugged when trialled on both source and amps compared to the MIT I use.

Hi,
I have a Threshold SA-4e poweramp and use a AC 12 power cable from PS Audio. Works very well here, better than the Silver Audio Wattmaster I had before. AC 12 provides great resolution and details!

Jerrypan, have you had a chance to try out other powercords with the Pass amp?

Correo, I'm thinking of getting a PS AC12 for my XA30.5/XP-10. Is your amp Pass as well?

I wonder if Rrog has ever tried an aftermarket powercord? If he hasn't (none of his posts suggest that he has), it's very puzzling that he wrote so many posts on something that he has absolutely no idea of.

Try the Tara Labs Cobalt a/c cord!
