I have found that a really top-flight power cord is not necessary for my Ref. No. 32. I use a decent Essence cord, but substituting a Shunyata did not make that much of a difference (then again, the front end is plugged into a Hydra). I may be the case that the regenerating power supply of the Ref. No. 32 minimizes power supply issues. For almost all other front end equipment, I find the Shunyata cords to work extremely well.
I've also generally heard good results with NBS power cords, but, if you think the Shunyata Anacondas are expensive. . .
