Tube amp $2-3K used

Chris, I have an active crossover for that purpose. The overall system efficiency is about 88-89db. I have been known to play at realistic orchestral levels at times (90-100 db). The room is L-shaped in the rear and the length is about 25-27 ft with a 7-7 1/4 ft ceiling and the width is about 15 ft but there is an enclosed staircase on the right which reduces the usable width to about 12-13 ft. No need for balanced connections. As far as biasing is concerned, putting a screwdriver in a slot is as complicated as I want to get. Also I am 6'5" tall and about 300 lbs so crawling on the floor behind some amp while balancing some screwdriver and meter is out.

AudioK, I have a pair of Sforzando JL1 speakers. They are wonderful. Here's their website.

Greenman, I am using the AI3A preamp. Don't really want to get into the balanced thing. Aren't OTL amps prone to stability problems?

Trelja, I am in the NJAS. Know Russ and Fr. Richard very well. Needed to expand my net on amp choices to the internet audiogon crowd.

Semi, the only thing about SF amps is they are no longer made and what happens if repairs are needed?

Not being a tube god, I went to the ASL site and was further confused. How do you choose between the KMP Fox DT, Explorer 805 DT and Monsoon DT (a junior Hurricane). They are similarly priced and have different tubes. Any reason to pick one or the other?

Glai, any thoughts you have will be appreciated. Plus where did you hear the ASL amps?

Here's another question about an ASL amp although it could apply to some other manufacturers as well. The Explorer 805 DT seems too good to be true. SET, 50 Watts, fair price and built in meter. Seems like a lot of power from 1 tube.

I just read Art Dudley's column on the asl 805 explorer dt. It's an set amp. I am not a slave to measurements but 10% thd at rated power? I don't care if it is 2nd order harmonics that is still too high. Also having to correct bias during a long listening session is too much involvement for me. I'm heading for push/pull land.
