electroslacker: the 5A 250V will work both in Europe (220/240V) and the US. Fuses are supposed to blow when the specified current is exceeded (give or take a couple percent).
Tom: you piqued my interest as I never tried DIYing magnets before. I do believe in the enhancement that magnetic cables a la HFC bring a lot to the table. Care to share more? "Don’t do this at home" sounds like you are inserting a series of conductive N25 chips where the fuse is...cost is indeed a couple of bucks and a high(er) adrenaline every time you turn that thing on and hope your house circuit breaker still works. Am I close?
>>... no bang ...
well maybe a big one someday?
Replacing ferrous with non-ferrous material is known on/around sockets, I have replaced the standard covers with carbon fiber versions for selected sockets. I guess one of the reasons the PI Uberbuss works so well is that it comes in a wooden box that is on top treated with AVM paint. Basically, quality (some croy’ed) sockets, LC circuits, non-vibrating box and a steel AC sockets cover. I prefer Audience’s concept that truly isolates each socket, high quality caps and the use of a ground bar. As you know, they use their own dampening coating on their D models. It took a while before John McD decided to offer the superior GTX-D sockets as option. Their Cardas plugs are not in the top of the range.
As for fuses, I will order a Bee wax Super Fuse so I comp it between the SR Red and AH Platinum in my DAC
