Which Power Cords: I Need Some Informed Guidance


Working on a system upgrade. I recently purchased:

Krell s300-i Integrated
Cambridge Azur 840c CDP/DAC
Streaming Apple Lossless wirelessly from a G4 Powerbook (other side of the room) into an Airport Express, then optical out of the airport, into a Musical Fidelity V-dac, then RCA into the Krell.
Ps Audio Quintet Power Conditioner
I'll swap out outlets as well...sometime soon.

Looking for Power cords. Something under $350 or so.

Any and all feedback is greatly appreciated.

Thanks,

"After market power cords can lower system noise by reducing noise in the AC delivery"

if this is true, and I have every reason to believe it,then what will happen as they "break in"?

I am sitting here listening and typing this string.I have just installed these power cables and the more I listen, the more I am impressed.They have really improved the system significantly.I am now a believer.

It is really exciting and improvements always are, but if things get better still by break in, then I am a happy camper.

These power cables were very inexpensive, $37.00 each. Unfortunately the only components in my system that can use them are my Acoustat 2s. It makes me want to get my Hafler 220 modified to use a non-hardwired cable.I imagine this is doable. Most of my gear is Audio Alchemy and use out board power supplies.

I've been on the powerchord train for awhile and just got off. Two Shunyata Taipans for my SimAudio monoblocks. Audience powerchord for my DAC and Audioquest for Sonos. I'm happy with all the choices so far. I notice a much much lower noise floor. Looking forward to the Shunyata SR- Z1 outlets. Those heavy cables can sag from the sockets. Don't forget your outlets guys!
