Goodness, it's not his amp or fuses. The Maggies are a fussy speaker for placement, that's Maggy knowledge 101. Suggesting that someone try a Bryston, when he's got quite a respectable integrated amp, does not seem helpful.
If the speakers aren't blooming well, then attenuating the tweeters by installing the resistors won't create more bloom.
People aren't reading the thread. The OP mentions his amp(and clearly mentions his issues) and people are suspecting the amp, and asking why he won't mention it. Sigh.
Beernut, you seriously can't go wrong with either the Tannoys or the Klipsch for the kind of music you prefer. I'd say your research is bang on. I'm suggesting Tannoy because I own them and prefer them over the Paradigm, Ascend, and Pioneer speakers I've compared them to. But there is a big following for Klipsch too.
