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?

The advantage of running 25 foot speaker wires underground is no one will step on them as they cross the room.  
This would be a good example of how to benefit from balanced line operation; running long speaker cables usually results in a loss of definition and bass impact. If the amps are kept by the speakers (not always possible) with the same cables but much shorter, and then balanced lines are used to transport the signal to the amps, the result is often greater definition at all frequencies.

I'm speaking from direct experience; I used to run speaker cables of the same length! The difference was easy to hear.

Robert agrees but he doesn't hear any loss of bass.   Now with the black duplex, the immense bass is tight, deep and moves enough air that you can feel it.  That's one area that I'm sure is just fine especially with my Grover Huffman large gauge speaker wire.  As to definition, this system way outshines my living room system which has only 6 feet of speaker wire and is driving 3 10" woofers deep and tight, same speakers as Frank.   My wife complained that her Metallica has too much bass on the main system with the new duplex . Otherwise, you are correct with having better sound when amps are proximately located to the speakers.  I can't run balanced cables in my system

When I built my house I contemplated placing the amps near the speakers by putting in two underground floor duplexes at the speaker locations.  I'm using them for Shakti air boxes instead

^^^  Steve ... You have such a beautiful dedicated room for your main system. How about posting it on the "Virtual System" site? I'm sure the other members would love to see it.

i just ordered the black duplex mainly because of the free fuse.  I think the bass in my system is good enough already.  I am hoping the duplex will make things more warm and musical instead.  Did I just make a wrong move?  Got 30 days to try it out.  Looking forward to hear the final outcome from fleschler.
