Aren’t most better grades of audio devices fused at the point where the power comes in? I tried looking for a schematic of my Macintosh amplifier and I found one but it was a little fuzzy. It looked like there was a fuse that one across both the hot and neutral. So here’s my point, Are you bringing this power from the street then step it down at a transformer to 110 V and then it comes through your breaker panel, goes through the walls in the form of solid Romax then goes into your $800 power cord and then it runs into a fuse. The last time I looked at an audio fuse it wasn’t much bigger than a human hair. So you’ve got this alternating current going in and out of your amplifier which has the pass-through this fuse. It’s like a major choke point. It’s not like putting a bigger fuel line To a motor.
