audio research REF 150

How much is the new Ref 150 ?

That's what I've been told as well. (last post, not the former)
Can't wait to hear it!

Ref.110 6550s >Ref.110 KT120s -Slight gain in power and improved dynamic.
Ref.110 KT120s >Ref,150 -Improved soundstaging and delineation of instruments (separation). Tonally, fairly similar in character, but with noticeably better bass--lower, tighter, punchier (control and extension). Overall, imo, the added performance more than commensurate its price increase over the KT120s equipped Ref.110.

Why dosn't ARC's website mention any of this? Any REAL reviews yet?

The Ref 150 has slightly larger transformers to better utilize the new KT 120 tubes. You can also use the KT 120 tubes in the ref 110. The Ref 110 will sound a little better and give you a bit more power. Because ARC changed the transformers for the Ref 150, the Ref 110 is not upgradeable therefore the changed in model number. I have not heard the Ref 150 yet but I don't think that the difference will be significant. If you have a Ref 110 than I would consider using the KT 120s the next time you re tube.

Now don't beat me down, I haven't heard it yet, but 2 of my trusted ears have said it is amazing. A total rebirth of ARC!
