I don't yet own an Accuphase amp, but the difficulty of getting to the fuse may deter me from trying to tweak it that way.
I have never tried the blue fuse, so I can't say. I can tell you that the purple is very good.
Accuphase, fuses
Hello,
Reaching out to owners of Accuphase amps and integrateds, and also digital components. Do you, or have you ever, tried to swap out the fuses with aftermarket fuses? I don't yet own Accuphase but am thinking about going that route. I see many photos online of the interior of Accuphase gear, but I see no obvious fuse holders. In fact, it looks like you would have to remove things in order to get in the vicinity of the power inlet. Which I am not about to do. If the fuses are inaccessible, that would almost be a relief. One less tweak to be done with. ;-)
