Lamm 1.2 vs. Pass xa 60.5

I just went from XA60.5's to XA100.5's driving my Avalon Eidolons in a 12' x 14' room. Because of the small room, I was thinking I wouldn't hear much of a difference but boy was I in for a surprise.
The xa100.5's took command of the speakers. Better bass control and depth, but the real surprise was the improvement in separation of I instruments and a more 3D soundstage.
Boxing up the xa60.5's this weekend as the xa100.5's are staying :).

I think, the Lamm units in general are very reliable. I never heard - or read - that any amp got a problem...such a "rumor" is unknown for me.

I own Lamm M1.2 monos. Not only are they the closest to live music I've
heard, in terms of amplification (and although I haven't heard them all, I've
had Bryston 9BSTs & 14BSTs, Levinson 33H monos, and a few others), but
I've never had any reliability or performance issues. Moreover, when I first
purchased them, I had them completely checked out my Vlad Lamm
himself. Their customer service is superlative, to say the least. Lamm is my
last stop in both amplification and preamplification (I also am fortunate
enough to own the venerable Lamm L2).

I don't know about the comparison with Lamm, but it's interesting how different some of the opinions regarding Pass are in here compared to most other threads. I've never heard the XA series described as lifeless or lacking emotion before.

Stereophile can certainly be criticized, but their review was pretty clear: "I don't have much to say about the Pass Labs XA60.5 other than this: It is the best-sounding amplifier I have ever used."

Anyway, if you do change amps (or already have), please remember to update the thread; it'll be informative to others to read about your comparisons. Good luck.

Syntax wrote regarding the XA 60.5:

"I missed the emotion which is part in any music."

Can you tell me what the rest of the system was that made you feel this way? Am wondering how you can make this very confident statement without qualifying it further wrt ... everything else.
