Best AMP for Avalon Eidolon, ARC, CAT, VAC..?

I use the Atma-Sphere MA-2 Mk.III OTL amps with my Eidolons and I love the combination. The MA-2 makes for an incredible match driving the Eidolons: superb speed and resolution; exceptional recreation of correct timbre and harmonic overtones; deep, tight, agile and articulate bass; holographic soundstaging; dynamic range capacity that just won't quit, and delightfully natural, relaxed and musical throughout (never in the least lean, etched or analytical).

I've spoken with some Eidolon owners who use the Atma-Sphere MA-1 and report good success, but I play a lot of large orchestral music so the added power and control of the MA-2 made most sense to me, and the MA-2 is completely versatile in being able to drive almost any speaker out there. Don't let the fact that it is an OTL fool you; this is one OTL that will drive virtually ANY load.

Also, Ralph Karsten is one of the best designer/ manufacturers in the business for taking care of his customers and supporting his product. The MA-2 has been in production for well over 15 years with continuing improvements, and every MA-2 in the field today can be updated to full current factory specification. And I don't know of another manufacturer who will give you a complete "as new" warranty upon upgrade to current factory spec as I received upon upgrading my MA-2 from MkII to MkIII status this past year.

Gregadd, the bass reproduction capabilities of the Atma-Sphere MA-1 and MA-2 amps is one of their remarkable features. With appropriate speakers, one has the best of solid state bass with the beauty of tubes through the midrange and top.
