HCM Audio has been running a special on AudioQuest power cords, plus another brand, for some months. I bought 3 of the AQ AC15-1.6 H/S models (these have the Hubbell male plug with the Schurter IEC female at the other end), as replacements cords for my Bryston preamp and power amps. I ordered all 3 cords with pairs of AQ's ferrites, which reduce RFI and EMI. The build quality on these cords is very good, and they cost $50-75 each, depending on length. I honestly can't say that I heard much difference, but I am also told that the Bryston amps seem to benefit less from upgraded power cords. However, if you want to experiment with decent cords without a large dollar investment, check out the power cord specials on HCM's web site: www.hcmaudio.com
