Pass Labs INT-150 is $6500 (you could almost buy two Ayre AX-7's for that), and
looks not unlike the Ayre in that it is a billet box with fins and blue LCD readout. I've not heard it. I have heard a few of his X series and would not have associated that sound with the Ayre amp I heard. Pass occurred to me as a bit cleaner and crisper for lack of a better descriptor. Ayre sounded a bit more relaxed and natural and reminded me of tubes in the way it softened what might otherwise occur as hard edges. I don't know if their integrated is fitted to that mold (based on the X series), but I'd guess it was, as opposed to his First Watt stuff, which I've also heard in passing and reminded me more of what I heard from the Ayre, though they are not the same beast. You may also consider buying used, which typically is about 40-50% off list depending upon the product and its condition. Man, for me it's all about the music and how the gear presents it. If you don't like the look of it you could always put it behind a cabinet door so you don't have to look at it.
Jaybo - you're hilarious!
