Audio Research and Acme Audio Labs fuse


I’m toying with the idea of going down the rabbit hole of upgraded fuses.  Looking over the usual contenders I stumbled across Acme Audio Labs. Their philosophy of best bang for the buck certainly appeals to my wallet (@$20 a fuse).  One caveat, however, is they warn that their fuses aren’t for all components.  Specifically gear with “no inrush protection“ will cause their fuse to blow prematurely.  So my question to those reading this: 1) Any experience with Acme Audio Lab fuses, 2) do they “play well” with ARC, and 3) does ARC gear typically have inrush protection?  I’ll be experimenting with the fuses of a LS 27, PH 7, and a pair of VT 150 mono amps.

Yes the fuse, IEC and AC wire are all part of the power supply. Yes the power cord is part of the power supply. The quality of incoming AC impacts the sound and is indeed part of the signal path. If you don’t think so, then try playing music without these parts in place.


Based on the Acme Fuse verbiage I would buy the QSA Light Blue fuse from the Tweak Geek. They are $70. You will hear a nice sound quality improvement. Use the same value as the one in there now. If you don’t hear the sound improvement after a week or so, then just return it for a refund
