Amp to match Avantgarde Uno G2 horn speakers


Hi, I listened to a pair of Avantgarde Uno G2 horn speakers two weeks ago and was really captivated by the sound. I heard it driven by an Audionote Meishu SET amp which outputs 9 wpc. Since the Uno G2s have a sensitivity rating of 104dB, that was more than sufficient.

What I'd like to know is: is there any other amp that would be a good match for the Uno G2s? Must it be a SET amp to bring out the best of the Avantgarde horn speakers? I noticed that Avantgarde dealers will invariably sell Audionote tube amps too. How about the Pass Labs XA30.5 pure Class A amp? Would they drive the Uno G2s well? Looking forward to your replies. Thanks.

Best matches I've heard:

-Lamm 2.1
-Audiopax 88
-First Watt F3 and J2
-Viva

The nice thing about First Watt is that you can have an in home trial from Reno HiFi. The F3 was wonderful but not a great match with my Hovland HP-100.
I heard the big Avantgardes in the NYC show a few years back with B.A.T. amps and I was very impressed. There was no shout factor, tinnyness, or bass boom. It seemed just right and very involving. I forgot if tubes were involved.
The UK importer of Avantgard, Graham Tricker, is a great enthusiast for the speakers and of course, is Tron Amplifiers also. I don't know that Tron amps were voiced with Avantgard in mind, but they did sound very good together, when I went to pick up my turntable.
Tron are well respected anyway, try googling the name or GT audio is his UK website
Can anyone here read Greek? Some years back a Greek reviewer bought an S-30 from us, for use on his UNOs, and he sent us this:

We always assumed that it was a good review, and he did comment to us that it was an excellent match for the UNO.
You may want to check out the Serious Stereo 2A3 amps. These amps sound incredible and should be a good match. I am using with 101db sensitive speakers with great results.
