McIntosh fuse changeout to make better sound

Nightingales have no song of their own to sing, they only mimic the ones they heard.
I only listen to those who know; how the weave, got wove.

@robberjobberman  My three blue SR fuses make a very significant upgrade over standard buss fuses in my custom tube amps and highly modified Dynaco ST70.  However, they apparently make no difference in some equipment, including an EAR 864 preamp.  Same with the power outlets.  SR blue (black and red as well) outlets are superior to my former Hubbell hospital grade outlets.  SR says it's the 2 million volts they subject these products to and graphene coating.  I don't know but the proof is in the pudding.  Wonderfully enhanced listening.  I've given back two of SRs more expensive products as doing harm rather than good.  However, I rely on SR's HFTs (32 in my main listening room) for acoustical treatment along with Hallographs and acoustic paneling.

I just putt an AMR. fuse in my Ultimate 70 Van Alstine two days ago. 
This was after I had put two into the tube preamp, I had it connected to. It also helped soundstage and tone. I have not gone beyond the 15 buck per fuse level. I can tell you I have been using them in sources also, for a couple years now.

Naysayers should read some of the European reviews of aftermarket fuses where some countries mandate fuses in the housing of the mains lines plugs. Of every one I've read that was for a TV, they all reported improved TV performance, which can actually be seen. It's along the same lines as what I've seen with better AC cords and power conditioning. 

That, and all the qualifying statements from those who've yet to try it makes one wonder, why bother debating, for they'll never know and will always complain, using the same, tired points.

And, it would be nice to see them stop using the medical analogy of placebo, since a placebo has no medicinal effect whatsoever when measured against a real drug and with any piece of audio gear, there actually is something of relative value and performance going up against what you're supposedly testing. In other words, they both work along the same lines for the intended purpose. One just happens to be better than the other. Leave the price of it out of the equation and they'll find themselves balancing on one leg.

All the best,

I’m auditioning a couple of fuses, more out of curiosity. So far, I won’t say all of a sudden my system is night and day different , but there is a noticeable air that didn’t seem to be there before. Low end is a bit more solid etc. I’m a fan.
