Synergistic Red Fuse ...

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.

100 hours on the duplex with standard fuses. They appear to have broken in so that the mids are balanced with new superior bass and higher treble ranges and the ambiance, reverb, natural decay and air which was awol for the first three days are back. They sound similar to the black fuses. They may require an additional 100 hours to get to that place where the fuses were so beguiling and lush sounding. I will be installing the fuses after another 2 or 3 days just to see how far the duplex sounds.

A25105. The black fuses in my main amps only after only 2.5 hours made my system addictively richer, more detailed, and more musically interesting (until they blew).  They were rated 5 amp slo-blo.   SR Elliott is sending me 6.3 amp fuses.

I also installed a duplex in my living room system. That system consists of highly modified Dynaco ST 70 voltage regulated (not a ultralinear tap design), custom tube preamp, modified pioneer DVD-05 DVD/CD player (six big caps, high end Power cords on all equipment), Kenwood tuner and Legacy Signature 111s.
The black duplex after 24 hours showed great improvement in smoothing out high end peakiness from the rear tweeter, better integration of sound, wider soundstage, and the same punchy deep bass as before. My wife liked it immediately compared for the bad taste from my main system after 30 hours. I will be installing a 4 amp fuse just in case as it is rated 3 amps but SR Elliot recommended the higher rating.

If if you have the Teslaplex SE and replace it with the black duplex, put it on your television/cable box/blue ray player. I have a 75" Sony x940C and it improved the picture. The other big TV improvement (my wife told me to keep the tweak because it the picture was obviously much better) is to install a set of Stillpoints ultra-minis under your cable box.
