Best Class A amp with SLAM


I'm looking for a couple of great class A bias amps (monoblocks) with the best "slam" as well as a sweet sound.

I recently sold 2 Krell KMA 160 mono blocks and I really miss them. What's out there that has the same attributes? I want 100-160 WATTS RMS that I can weld with if I want.

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..
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.
Why do I have this feeling we will be hearing about Monitor Audio speakers yet again...
