Avantgarde Horns - amps you've tried and love?


My current system is:
dCS Verdi, Purcell, Elga+ (all 1394 latest models) to the Art Audio Jota with KR 300BXLS tubes to the Avantgarde Duo horn speakers. Cables are NBS 0 for digital and HMS interconnects/speaker.
Question: I'm planning on the purchase of the Audiopax but before I make the plunge, I'd like to ask for other Avantgarde owners input on amps they have tried and what their impressions have been.
Thanks in advance,
Jack

One of my customers has Duos and had been using a Berning Siegfried 300B. He replaced it with a Kronzilla and reports good results. Anyone wanting more information, please email me offline.

I'm still using my Quad IIs. They've been rebuilt by Graham Tricker at GT Audio (maker of the Tron brand of british high end tube amps). I've heard the Duos with Tron's 300B monoblocks and 845 monoblocks. Both are very good.
The important thing about the Duos is that your amps need to be quiet with zero noise.

I'm using Audio Note Kassai monoblock power amps with my Duos. Enjoy listening to female voclas and this combination gives a very sweet sound. By the way, preamp is Nagra PL-L.
