Thanks Kijanki, Al, and Mapman. I appreciate your support throughout this largely absurd endeavor.

05-18-12: AlmargThat's a good idea, Al. I will test it and report back.
One piece of data that I think might be worthwhile appending to your report would be what your line voltage is, for the conditions under which you ran the tests (time of day, things turned off, etc.).
05-18-12: TmsoroskNOOOO!!!! You are tempting me to buy YET ANOTHER fuse! I don't know if I can bring myself to do it. Am I really that stupid? Maybe. It's additionally tempting because the Hifi Supreme fuses are designed in collaboration with Mundorf, and I've been very happy with the Mundorf caps (both Supreme and Silver/oil) I've used in the crossovers I built for my speakers. Hmm.
...too bad you weren't able to test the High Fi tuning Supreme fuses, they really did make a difference and you don't need to listen very closely like you do with other fuse comparisons.
05-18-12: GeoffkaitMy expectations were the same as yours, Geoff. The Isoclean fuse WAS perceptibly better than the stock fuse, but not by as large a margin as I was expecting, given my experience the other day. Don't know what to make of that.
...whatever happened to the word Terrific you used when you couldn't resist replacing the fuse in the preamp a few days ago? I was all set for a rave review.
I still say wait a few days and re-evaluate the sound after the power cords break back in.I agree that long term listening often reveals things that you can't hear during A/B tests. But I can't bring myself to devote a week to testing each fuse. I must try to have some semblance of a life. :-)
