Thank you both for you replies......Love my BCD-3 ...
All I can tell you is that when I first read the hoopla about such fuses, I decided to do a little research. I discovered that the manufacturers of 'audiophile' fuses provided scant information about their 'fuses', omitting the most critical parameters of their performance. So, I contacted two of them, inquiring about clearing time, etc. One manufacturer didn't respond and the other avoided specificity, but stated that their fuses were all of the slow-blow variety. In other words, if you love your BCD-3, don't replace the fuse that Bryston's engineers carefully selected with something that won't clear in time to prevent extensive damage in the unlikely event that something goes wrong.
