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?

Here’s the AH site: http://www.audio-horizons.com/pages/fuse.html

Regarding the sound of the AH Platinum Ref fuse... it may be a bit warmer and richer than the stock fuse... and... maybe a bit less clear in the upper mids and highs than the stock fuse - difficult to tell since the differences are so subtle.  Sort of like the difference in the sound between silver interconnects and copper ones.

Although you do not have fuses, Installing the Synergistic Research Electronic Circuit Transducers (ECT) in your CD player may result in a major improvement in sound. I have them in both my SACD players and they are effective. Same return policy as the fuses and removable if you sell your player. The fuses + ECT's in a cd player is very nice.

Three screws in back secure the lid. After removal the lid slides back about 3/4 inch and then lifts straight up and off. You will have to use a thin Blade screwdriver to get the lid to slide back. There are 7 fuses in your player. I have replaced all  7 - great improvement. But you will get a significant effect replacing just the main power fuse. I suggest using a 3 amp small slo- blo BLACK fuse instead of the original 2.5 amp fuse. Fun to look inside that player. I like mine !!

I would suggest replacing only the 5 amp fuse at the IEC inlet. On my OTL Eddie Current Zana Deux headphone amp this made a nice improvement.

Thank you Charles, look forward to traveling the path that you guys have been point on for some time now. I’ll be happy to offer some impressions as soon as they arrive.

I will buckle in for the long drive oregonpappa, thanks for an eta. As with all journeys, beyond the ride, it’s nice to know that the destination is totally worthy of it.

David, sounds good, thank you for your thoughts on the power amp fuse upgrade positioning. How do you like your Zana Deux OTL, need I ask? I’ve always admired the Moth designs and what Eddie has gone on to do.

Happy Listening!

Hi Audiolabyrinth:

Absolutely a used market for these premier fuses depending on the values would be my guess.
