About a month ago, I responded to a thread on this subject. I have two Bryston amps (4B-ST and 5B-ST). I tried several of the more expensive power cords, and then bought a pair of AudioQuest power cords from HCM Audio that were/are on sale for under $100 apiece. I ordered two of the AQ power cords with upgraded Hubbell hospital-grade male end plus an upgraded IEC plug. I did not / do not hear much difference from the stock Bryston power cord -- and other Bryston owners on this site seems to concur. So, if you want to invest in power cords for your 4B-ST, just to be sure you aren't missing anything, go for one of the more moderately priced cords. I'd start by checking out HCM Audio's Web site (www.hcmaudio.com), and clicking on the link for their specials.
