Best power amp for Avalon Opus Ceramique

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.

Vicdamone - thanks for your question. The V-1xe is going to a friend. The 850 are more detailed, more 3-dimensional and have much better bass control. Nevertheless: the V-1xe is a killer product in its own right. I like Ayre a lot and as far as I can say: Charles Hansen is a very honest person who builds the products with the best price-performance ratio I know.

Mu6: you should give audio aero a try. The new Capitole Reference SE rests among the very best cd-players on the planet - regardless of price. Nagra - own sound ??? NO, never ever. A bit weak in the base line: YES.

I would try a used Gryphon amp (Dm100 or Anthileon)
worked excellent for me, best match for both my Avatars and Eclipses.

Elberoth2 and Jttn are off the mark. My H2O Signature monos, with their
upgraded ICE modules in place, have mids and highs to die for. I do not have
Avalons. My amps are running a much more difficult load.

I don't compare my system with other systems. It has to sound right
compared with real performances. Matched with the same maker's Fire
preamp, and an Audio Note DAC, I am at end game.
