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.

"...deep, tight, agile and articulate bass..."

Rushton that is quite a compliment coming from a tube amp. If my memeory serves correct you do not use a subwoofer. Every amp I use get's the benefit of not having to reproduce the low frequencies, which can be a strain on the amp and speaker.
I was considering atma-spheres but the electrical sysytem of my apartment will not support the heavy current draw. Nor was the the ML/CLS an ideal match.

Back to the point try Rowland if you want solid state. They are very sweet.

Accent: Mr. Levi reviewed and purchased the EAR 890's a few years back and just rereviewed them. In this latest review his opinion was that the NuForce did hold an edge over the 890's in bass reproduction though.

I listen to a great deal of FM. My tuner sits just 18" above the NuForce SE's which are close to the floor. My yagi antenna is masted on the roof of my ranch style home. The only FM interference I've encountered with the SE's was from my clock radio whose little wire antenna was moved up off the floor and the problem was solved. I should point out that I use heavily shielded DIY VAC cable, stare grounded long before the SE's arrived.

I also own Eidolons and use a CAT Ultimate MKII preamp and a CAT JL-2 MKII Signature amp. I was happy with my system until I evaluated a pair of NuForce 9.02 amps in my system. I did not realize that the Eidolons needed an amp with a much higher damping factor. I just ordered a new pair of NuForce 9 SE amps. They are that good.

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.
