Which Power Cord are you using with Parasound A21?

It's very easy to make a mistake with PC's. I wouldn't take a chance and buy one without a demo. If you call The Cable Co., they'll lend you a few so that you can try them in your system first. I've been using them for years, and wouldn't do cables any other way.

Also, it won't be random selection with them. They ask anyone who demo's cables to fill out a form that spells out your likes and dislikes of all the cables you try. The A21 is a very popular amp. They will tell you what cables past customers liked the best on the A21.

I use a PS Audio power cord.

Of all the cords I've tried over the last two years or so the Kimber Pk 10 Golds are my favorite for amps and power conditioners. The Pk 14 Golds excel for preamps and sources. Hands down the best tone and overall balance for either the 10s or 14s depending on application. YMMV.

Have a Parasound 2125 amp. I use a Iceageaudio power cord. Price well below other cables using the same technology.

I went from the Pangea AC-9SE to the new AC-9XL and the difference was astounding. There was an across the board improvement in sound on pretty much every parameter. Previously I had felt the sound of the A21 to be a little dark - the AC-9XL made it sound more open, refined and powerful at the same time. My 2 cents!
