audio research REF 150

Very well designed amp. Well behaved. Put out about 148W across 8 ohms. Single channel driven.

Anybody else compare the Ref 110 (both with 6550 and KT120 tubes) with the new Ref 150? If yes, can you comment on sonic differences and whether the extra $s to upgrade from the Ref 110 is worth it? Thx

the ref 150 sounds better than about any ARC amp they have ever made, considering it has enough power for you. It is NOT just a tweaked ref110. go listen to it if you can, I was very impressed , I own Rogue m180s by the way.....

The REF 250 introduced at CAS. The best tubed amp on earth?????

Considering replacing my beloved GNSC modded Classic 120's with the REF 150.

I may have missed this if it was already posted, but the REF 150 also incorporates the same type of capacitors used in the REF Anniversary preamp. The transformers are upgraded, the caps, and the KT120's are, I believe the major differences. My understanding is that it has about the same energy storage, about 1,000 joules, as a single 610T. I should mention that I'm a dealer but I haven't heard one yet. I'm also a passionate music listener and I'm anxious to hear one.
