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?

Sonic Frontiers Power 2, better than ARC VT-100 of any versions in most area for less money used.
The ARC amps are out if your not into doing some work to bias....... This does cut down on your choices considerably. Maybe the amp you hould look at is the Sonic Frontiers, like Semi Say's. It biases from the top using LED's that tell you when your good to go. They are decent amps, and you can get them serviced by the Parts Connexion guy. I have owned one of these amps (Power 2SE) and ended up selling it for an ARC VT100II becouse I thought the ARC sounded better........ Having said that though, the SF is a lot easier to keep up with.

Assuming the impedance doesn't drop appreciably below 8 ohms the Atma-Sphere M-60 II.2 could be an excellent choice and it is in your price range used. Extremely easy to bias, works very well with inexpensive output tubes (doesn't require matched pairs or quads), reliable and has the OTL transparency unmatched by any of the other amps you listed. Does your crossover allow you to run balanced? What preamp are you using?
That's interesting observation Chris made.

I had VT-100 Mk 1 & 3 in the past, a friend let me borrowed his Mk 2 for a week. I have also had Sonic Frontiers Power 2, 3, 2SE and currently own the 2SE in addition to BAT VK-75SE among others. Side by side with BAT VK-75SE, VT-100 Mk 3 sounded rough, lack delicacy, slow, congested, etc. I could not believe my ears, neither can 3 other of my friends. Bass was not any better, it was such a disappointment I sold mine after a couple week.

However, SF Power 2SE (or even the plain Power 2) comes close to BAT! Bass weight is significantly better than BAT, but BAT is faster in bass, or faster overall. Top end extension, delicacy, air, refinement are all top notch like BAT, but BAT is still a touch better and expected given the higher price and lower output. I also owned BAT VK-150 (not SE) in the past, SF Power 2 definitely sounds better than VK-150 overall.

This is heard in the same system that includes SF Line 3SE and Sonus Faber Amati Homage, no other variable changed.

And like what Chris pointed out, SF Power series allow you to bias individual tube from top like a true reference grade tube amp. Only in ARC Reference series do they allow you to bias each tube. Reason is manufacture cost and VT series single resistor bias scheme is a very compromised design. For SF Power series, you only need to check bias once every few months, very little work involved.
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?
