Best power amp for Avalon Opus Ceramique

Mu6, so Stillpoints under the Eidolons?

yep, you need them with inverse risers or mini inverse risers depending on the type of floor. with carpet you can use the inverse risers en with hard floors like wood or tiles you can use both. Just place the inverse riser on the floor and insert the stillpoint with the ceramic ball down, the metal bottom with the logo should touch the bottom of the speaker. 3 stillpoints for each speaker will be sufficient. each single stillpoint can bear 100lbs, so no problem here.
And it looks good too!

Thanks for the comments. Regarding the Ayre V-1xe - I´m going to replace it soon with Boulder 850 mono amps (different league).
Regarding K-1xe (awful design - great sound but no contender to my nagra PL-L). I had a D-1xe on loan (grat sound but awful design and inferior to the new Audio Aero Capitole Reference SE with build in pre). The GNSC modded 861 is far better than D-1xe and offers build in pre as well.
Stillpoints are great !!

Frankpiet: Thank you for the comments. I heard the Nagra once in my system but has too much sound of its own and lacks deep base fundamentals, also don't like the design. I don't know audio aero, but never heard interesting audio from France. They have good wine and food, but about audio? So I have my doubts. May be i'm wrong.
I like the design of ayre very much, it's more like no disign which leaves your mind open when you look at it. Probably it's a matter of taste.
I'm very curious how the Boulder will be compared with the Ayre. When it's really better I will always concider to buy it. So let us know.

Frankpiet: I hope you can take the time to give us your detailed impression of the differences between the V-1xe and the 850's. I have a buyer for your used V-1xe if you choose not to list it, drop me an email.
