Best amp for Avalon Eidolon speakers?

Thanks to all of you who have commented so far for sharing your considerable knowledge and experience. I will work on optimizing room placement of the Eidolons first, per your suggestions, and then try some of the amps recommended. Additional comments are certainly welcome. There seems to be some difference over tubes vs. solid state. Anyone have more to add on that? Are tube amps a lot more trouble?

Regarding the 2003 CES displays using Eidolons. According to the Avalon website news, Eidolon Diamonds paired with Ayre V5x amps and the Ayre K-5x preamp was voted best sound at the show. And Accuphase amps were used in another setup with Eidolons. Anybody hear any of these and have any reactions?

Lloyd: You'd be doing yourself a disservice by not listening to the Edge solid state amps. I can state my NL-10 makes musical magic w/my SF EAIIs and my Accuphase 75v.
At the past several Las Vegas THEs, Edge has driven different speakers each time, yet garnered "best sound" each time.
Tom Maker is great to deal with and you can work out a trial quite easily.
(Of course, I have no financial or other interest in the company).

Lloyd,
I honestly don't believe there is a single best amp for Eidolons. Provided you give them enough power and current, Eidolons are so neutral that they will reflect whatever character is passed to them. In that case, it is mainly a matter of choosing the amp sound and price point you prefer. I've heard reports of success with nearly every (larger) solid state amp made, and with a goodly number of tube amps too.
