I have auditioned a few (but none of the big names such as Whale, Fim, Electraglide, etc.) on my 4B-ST had noticed no appreciable difference. I was willing myself to hear something better but alas I could not. Sometimes I keep things knowing that I have done what I could to maximize my "audio return on investment" but this time I just let my ears decide the supplied cord is still in place...I e-mailed Bryston after the fact and they do not believe that pcs make any difference and recommend using their provided cord.
I distinctly remember reading a post sometime back advising the the Bryston amps worked better without using a power conditioner - have yet to try this so no personal results as of yet. Never tried a pc on a Bryston preamp...Possibly other owners here may offer more assistance.
