Best Integrated, period.

I think the Pass is basically their X-150 amp with a passive pre, I don't think there should be any complexity or compromise that might occur when building a pre into an amps chassis. Pass certainly knows how to build amps, adding as passive attentuator (perfectly matched to the amp portion) should make for a great integrated, assuming you like the sound of a Pass amp, I do. I've not heard the integrated, but I would be shocked if it was a mighty good one. Not bad looking either IMHO.

Is the INT 150 the Pass model we're talking about?

Is there another Pass integrated besides this one?

No. I think that is their first and only.

While it may not be the "best" in absolute terms, the set of two Pathos Classic One MkIII tube hybrid integrateds running in Mono mode are wonderful. I have not encountered another amplification scheme quite like it, nor one that sounds quite like it. Quite a lovely concept and execution.

At upgrade time I sold my MkII's to a man downsizing from Boulder separates. He was surprised at how little he gave up in terms of performance. I wasn't surprised.

The Absolute Sound review of the Pass INT-150 is in the September issue.

They said the front on view is "As imposing as a Peterbilt"

Neil Gader said "it's sweet and romantic, neutral and warm". Robert Harley in a side bar to the main review, "There must be a strong family resemblance between the INT-150 and the XA-100.5.

Neil went on to say "It's a musical force of nature."

You have to take reviews with a grain of salt, but as a former Pass Alep 1.2, 3, J, and XA-30.5 owner, I can tell you that Pass SS is very special and the only SS (well, maybe Ayre)that appeals to me, though I still prefer tubes.
