Synergistic Red Fuse ...

I installed a SR RED Quantum fuse in my ARC REF-3 preamp a few days ago, replacing an older high end fuse. Uhh ... for a hundred bucks, this little baby is well worth the cost. There was an immediate improvement upon installation, but now that its broken in (yes, no kidding), its quite remarkable. A tightening of the focus, a more solid image, and most important of all for my tastes, a deeper appreciation for the organic sound of the instruments. Damn! ... cellos sound great! Much improved attack on pianos. More humanistic on vocals. Bowed bass goes down forever. Next move? .... I'm doing the entire system with these fuses. One at a time though just to gauge the improvement in each piece of equipment. The REF-75se comes next. I'll report the results as the progression takes place. Stay tuned ...

Any comments from anyone else who has tried these fuses?

On my HT system I have an Marantz SR6004 which has two of these resettable fuses in it. The one on the standby transformer during a power blackout blew, instead of resetting.

It was a pig to replace as it’s down the bottom of the three stacked boards and I had to remove all the boards and that bottom board to solder in a new one. If it was just a fuse in a clamp holder I could have replaced it easy with long nose pliers without removing anything.

I recently got a matched pair of Telefunken 12AX7s from from Andy Bowen at Vintage Tube Services. They replaced some Teslas’ (80’s or 90’s vintage) I had been running in my ASL Tulip 2A3 SET amp. The Teslas’ were supposedly made with Telefunken’s tooling, and I thought they sounded pretty good. The real deal Telefunkens blew them away. It’s hard to describe the difference; just more air, sense of space, transparency, detail, involvement & general musical goodness.

If you’d like to find out for yourself the difference really good NOS small signal tubes can make, give Andy a call. If you’ve priced NOS tubes elsewhere, you’ll be pleasantly surprised.

That's quite interesting but did you mean to post that here?

Yes,

This thread has become about more than fuses, and I wanted to to share with the good folks here 😀 

I know there are many who have and/or appreciate tube gear.
