Best amp for Avalon Eidolon speakers?

I owned Eidolons (sold them to move to the Diamonds- BTW, if you like the Eidolon's, listen to the Diamonds but that is a different subject). I started with a Rowland Model 10 and went to an Accuphase A-50V which was astonishing how much better it sounded than the Rowland. I still run the Accuphase with the Diamonds, althgough subjectively the Diamonds seems to present an easier load than the Eidolons. Within its power envelope I have also heard that the Model 10 outperforms the Model 12. Looks like Jeff is embarking on another power supply design with his new Model 300 series.

Mes used Eidolons with the Accuphase 50s as monoblocks........The speaker needs current to control the woofer and suggest SS over tubes as Mes had ACR Ref 300 Mk IIs on them as well and settled for the Accuphase....

Although Flex is correct, the DMC30sl is a much better preamp, than the original DMC-30, and has a smoother, and larger soundstage than the DMC-30s. Though it will be tough to find a DMC-30sl used; I lucked out. I forgot, a very low
cost way to go is Muse with the Muse 3 preamp and Muse 300
monoblocks. A very livable alternative until the savings account is full.

Albert,
According to Avalon site they had 3 rooms this year:

Opus Ceramique with Muse
Eidolons with Accuphase
Eidolon Diamonds with Ayre

As many of you guys I prefer Eidolons with high power tube amp,but I seriously doubt that either Tenor or tube Lamm amp would be a really god match with Eidolons.

BTW, Lloydj , having a right room with Eidolons is equally important ( if not more so ) as having right amp.

Agreed, Nar com. The Tenor and Lamms were shown with Kharmas at CES. It's very unlikely that the Tenors could drive the Eidolons well, though others have occasionally reported good synergy between the Eidolons and Jadis or CAT tube amps that are also probably underpowered.
