I have heard the Avantgarde Uno's paired with Audio Note Oto SE, and Graaf OTL. I have also heard the Duo's paired with Cary CAD-805AE.
Proper amp matching with these speakers is absolutely critical. I heard the Uno's with AN Oto and Graaf. The sound was simply unacceptable with Audio Note amplification - honky, flat, top rolled off, no detail. The dealer then changed the amp to a Graaf OTL amp - MUCH better. The speakers now started to make music but it still wasn't good enough. We could have experimented with more amps but we were running short of time.
The Duo's with the Cary did much better, probably because the Cary is exceptionally pure sounding in the first place. There was a problem with that demo as well but it was due to speaker setup not amplification. I agree with Chazzbo - the Cary 805's seem to be a good match.
Bottom line: on some equipment you can take an educated punt and buy with minimal auditioning. With your speakers, you MUST listen to how the amplifier performs. Good luck with your search :)
