Audiophile Fuses in Audio Research Ref Amps

[The Lost Bears]

Does anyone use one of the audiophile fuses in an Audio Research Ref Amp? I have a Ref 110 which like the Ref 150 uses a 7 amp slo-blo fuse. I went to order one of the Hi-Fi Tuning fuses today and found out they do not make a 7 amp fuse. The closest is either the 6.3 or 8 amp fuses. I looked at Synergistic Research and they don't seem to make a 7 amp fuse either.


So does anyone use an audiophile fuse in their amp and if so what brand?

Just my opinion, but I would rather have an 8 amp fuse that blew instantly than a 7 amp slo-blo fuse.

IMHO you should use the fuse supplied by the manufacturer. Audiophile fuses are in the same category as green markers.

I think the important thing is to always replace a fuse with one of the same type and rating as specified by the manufacturer.

I have to agree. I want to use the same value fuse that Audio Research intended.

Agreed, I would try 6,3A slo-blo as replacement to 7A slo-blo.

I use SR RED fuses in all my components except ARC. Kal doesn't recommend using after market fuses but I finally broke down. I bought IsoClean 7A Slo-Blo fuses for my REF250. Audio Magic and Audio Horizon offer a 7A but I'm looking for a neutral sound.

It's the same superlative so best to describe the improvements ... Paul Weitzel made me TRL PCs, basically FIM with a heavy solid core construction. It's has the best tone and color but a bit slow and narrowing of soundstage. I still use them sometimes ... a combination of Nordost Valhalla and TRL would produce a perfect PC.

The IsoClean gave me the tone and color of TRL PCs without sacrificing any speed, transparency, soundstage ... It still difficult to believe how 2 fuses can make such an improvement. I installed the fuse direction from back to front. It sounded great new but smoothed out after ~10 hours.

REF250 has 3 fuses but I'm only going to replace the main one.

Did you try the SR Reds in your ARC gears K?

I ran my previous REF5SE and REF150 with Reds and was pleased with the improvment over the factory fuses.

Currently running a Red in place of the mains input fuse on the 10, and was planning on the same with the 250se's

Ref250 is my only ARC at the moment so No.

So what SR Red fuse size are you getting for 250se? 6.3A or 8A?
