For amps I've listened to, these sound the best to me. Solid state, Jeff Rowland. For tube, Jadis Orchestra Reference(not Orchestra!) or the DA-30. Both Jadis amps are basically the same in the power amp section(4 KT90's + 2 12AX7's), the preamp section on the Orchestra Reference is passive, on the DA-30 it is active. I prefer passive. The DA-30 costs about $2000 more. The Orchestra Reference is newer, has their new KILLER cosmetics featuring stainless steel, 24K gold plated brass, and wood. The Orchestra Reference also has bass and treble controls(they want to see if there is a desire out there for these), don't worry about the sound being affected, the preamp is PASSIVE. Why is the Orchestra Reference so much better than an Orchestra? MASSIVE transformers(compared to only "huge" in the Orchestra), better internals, cosmetics, power, bass, sound, + the cosmetics. They really should have come up with a different name to avoid the confusion with an amp that is "only" rated Class A by Stereophile. In short the Orchestra Reference beats the smaller Jadis like a rented mule.
