Fuses that matter.

Gbmcleod, thanks for the report. I am not at all surprised by the comparison with the HF golds. That with the SR will be very interesting.

Terrific write-up, Gbmcleod. Can't wait for the next installment.

Well, perhaps more time is needed, but the AMR fuses did not come through on the amps as the fuse did in the PS Audio Power Plant. The sound is a bit cloudy, with a definite rolling off around 4k. Very much the opposite of bright: dull.

Which of you with experience with the AMRs has some idea if there's a break-in time with these fuses. The Synergistics - much as I hate to admit it - have been the best so far, but I haven not put the WA Quantums on the AMR. Even so, the AMRs have had around 10 hours and on Peer Gynt, cut 4, the triangle is so muted, I can barely tell it's there - except that I know it IS there. I turned off the amps, pulled out the AMRs, put the Synergistics back in and, while not in their full glory ( a function, perhaps of the CJ Classic preamp, which I suspect has slightly laid back highs, similar to the ET2 [ but I must state, I don't absolutely KNOW this: I've just NOTICED this since I've had it]), they are audible.
Do the AMRs have some kind of extended break-in time? And yes, before you asked, I've turned them both ways.

I have just installed the AMR fuses in my BelCanto ref500m's and also found that the sound shifted to dull and lifeless.
I also tried an AMR fuse in my Ayre CDx-7mp and found that the sound came alive resulting in a much larger, more defined holographic sound stage.
I am going to try an AMR fuse in my Calypso next.

Orelayer,

On your BelCanto monos, did you give them time to burn-in? Also, after they burned in, did you try reversing the fuses to hear the differences?
