Tube amp $2-3K used

I am in the market for a tube amp for my system. My speakers have separate bass units and sattelites. I have a high current SS amp for the bass units. What I am looking for is an amp that could give me 25-50 watts in Triode (although I am still trying to learn about ultralinear VS triode) mode or 60-100 watts ultralinear. My choices seem to be:
Rogue magnum 120-150
BAT vk60 or vk75
Cary V12 or rocket
Music reference
CJ mv 60
Quicksilver V4
I was also looking at the the AES sixpack but I heard they weren't the easiest amps to adjust bias on.

I listen to classical orchestra mainly, but I like to boogie with 60's to 70's rock as well. Any general suggestions?

SF is out of business for years, but Parts Connexion which is run by Chris Johnson, former SF founder, will continue to service all SF products. If you don't feel like shipping it all the way there, you can order schematic/parts and have your local technician work on it.

Mine Line 3SE developed the famous volumne pot problem. I ordered the parts, got instruction from them, replaced it myself in 2 hours. You can pay someone to fix it for less hour as well.

The Atma-Sphere amps, at least those made in the past decade, are extremely stable, you can even remove output tubes while they are playing (not that I recommend this). The two caveats in your situation are that although they can be run single-ended they are really designed to be operated in the context of a fully balanced system and that they don't especially like low impedance loads (the S-30 particularly).
SF amps can be serviced and/or upgraded by the Parts ConneXion which is run by ex-SF staff.

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.
