Lamm 1.2 vs. Pass xa 60.5

If you like the Pass sound, XA 100.8?.....but I´m sure the Lamm hybrids are very good as well.

Hasse
Even though I like the pass sound in the last few years I own the xa60.5 and owned the x250 before that, I want to try something else with the risk I will regret this move eventually...

In the June Stereophile, John Atkinson wrote briefly in passing about both of the amps in his review of the MBL Corona amplifiers. He felt that the Pass 60.5 excelled at soundstaging and image palpability, but lacked an iron grip in the bass (compared to Classe), and said the Lamms had a "forceful" sound that might lack the subtlety of MBL's big amps, but bested them slightly in ultimate authority in the lower frequencies. I haven't really heard the Pass amps at any length, but I can see where he's coming from on the Lamms, as I have always felt that they may not be the most absolutely transparent or best soundstaging amps I've heard but they have a power and richness to their presentation that I prefer. I think that they might give you more juice and bass control out of your speakers. Whether that offsets the apparently extraordinary soundstaging capabilities of your Pass amp (Atkinson's review makes note of that in a couple of places) depends on your personal preferences and priorities.

I listened to those Pass Amps but I never bought them. I missed the emotion which is part in any music. They are precise but never moved me, no matter what kind of music I listened to. Real Music reproduction sounds definitely different.
The Lamm 1.2R are a different chapter. Excellent soundstage, true in tonal reproduction, able to deliver the emotion from the Artist or Orchestra when it is recorded properly. A huge step closer to the real thing reproduction. Even when you squeeze it, the sound quality never collapses or will be compressed (getting harsh in the treble like a lot of other designs do). It is definitely a serious amp.
