Op...you really need to try one fuse at a time. Otherwise, you won't know which component sounds good or bad. My beef with SR is that they don't tell you the direction. With QSA fuses they do. I have all QSA yellow fuses in my system.
Fuse Direction for Pass Labs Amp and Preamp
I am going to re fuse my Pass X250.8 and XP-32 with Synergistic Research purple fuses in a couple of days. I was hoping to get advice on a rule of thumb for direction of the fuses. My instinct tells me to start by installing the fuse by the direction of the lettering on the fuses. I am thinking that the direction should be the lettering left to right with the beginning of the lettering facing out of the amp and the end of the lettering facing into the amp. Does this sound right?
