150 hours on my smaller living room system. It sounds so musical and non-audiophile (as in high end systems at audio shows). The Signature IIIs highs are now totally integrated with the rest of the frequency spectrum. The rear tweeter always (15 years) stood out and sounded a bit hissy. Not now. It doesn't have the tweaks or isolation transformers, Hallographs or Stillpoints of my main system. I ordered the black fuse for it. This system is just so satisfying that I didn't think about the missing the large room sound, additional ambience and detail of the main room. Plus, the living room is a better sound room and the sound radiates beautifully throughout the front end of the house. All this from a couple of duplexes, black and red.
As to the blown main amp fuses, SR Elliott is sending 8 amp fuses because my big amps have a massive pair of capacitors each as opposed to multiple small caps like most modern amps. He said that the big caps draw a big instant load and the fuses have to compensate (the SR fuses are rated for typical loads at 5 amps not my big loads). He also said he heard many stories concerning the idiosyncrasies of the black duplexes and fuses although my situation is rather unique. If David Prichard finds success in mixing duplexes and I've done the same in my living room system., I can do the same in my main system although that has separate 20 amp dedicated power lines rather than share the same power line as in my living room.
