Best Class A amp with SLAM

Ok, thanks Bo for your reply. Sounds good.

Handymann --

You should try out a pair of Belles SA-30 stereo poweramps in a (vertical) bi-amp configuration:

It may not look much on paper but, believe me, you'll be convinced of its merrits in-use. Simply put it's one of the best poweramps, if not the best, I've ever heard - price disregarded. Its sonic attributes are that of coherency, scale, ease, dynamic (both micro and macro) and transient prowess, naturalness, resolution, etc. In fact it hardly makes sense to point out specific areas it does well, it's just an overriding feeling of the music being unrestricted, indeed freed - there's really nothing it can't handle.

Perhaps it makes more sense pointing out what it does better than most amps I've heard; there's an inherent sense of power and vitality combined with an outspoken coherency, natural tone, and organic "vibrancy." Leading edges are sharp and clean, as they should be, yet in no way overpowers the flow of the music. To my ears this is a rare sonic combination.

For your information I have no affiliation with Power Modules(Belles).

Oh, pardon - it seems the Grand Slamm's can't be run in bi-amp mode. A single SA-30 mayn't suffice, but I'd try it out nonetheless..

Pardon again - Wilson Maxx II's...

The XA100.5 sounded great on the Wilson puppy 7. But for the Maxx I understand why you miss the slamm. I would try the X600.5. And yess you need the warm sound of an amp like the Pass. The Maxx can sound harsh. I heard them more often bad than good to be honnest.
