Alexx and Lamm ML1?

Gryphon Mephisto stereo is the least expensive amp I can come up with. Speaking new equipment. It's $65k or so retail.
Well, you probably could try D'Agostino Momentum amps too. Very different sound.

What first separates real life sound and reproduced sound is dynamics. You want to approximate as much as possible. As great as Lamms are they cannot do it. As for other elements, like timbre, Lamm might win. So..?
I would say much depends on what kind of music you mostly listen to and your priorities. It would be very tough choice for me if cost no object or almost no object.

Wilsons work quite well with many different amps, but if you want the very best, defined by you as very best overall, then it becomes a challenge to choose. I envy you, anyway, whatever you eventually end up with.
