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,
neutron
