I tried reading the AudioCircle Forum discussion on fuses. Modjeski is there and keeps talking about science, but after reading and reading never once did he mention any actual science. He did mention microphonics, only to say that can't be a factor but again without any actual science. When it got to where he was dismissing burn-in because nobody reported it prior to 1950, well totally lost interest. Only so much baloney I can take.
Possibly in spite of my initial impression the guy is not totally out to lunch. Don't know. What I do know, so much of what I saw is no better than any other guy with a keyboard and internet connection could do. So if you have a good link, something of actual informational value, please provide it.
Meantime, it is totally amazing how much improvement I heard immediately from just one SR Blue Quantum Fuse. Not that great at first, but reversed it and... awesome! One of them did blow on turn-on. Synergistic (well, technically high-end electronics.com) did replace it for free. After talking with Keith Herron we decided to go with a little higher value, and that one has been in there several months now. None of the others has blown. If any do, another call to high-end for another replacement.
