Amplifier for avantegarde duo 2.2?

Apparently, these work well with Avantgardes: (http://tomevansaudiodesign-usa.com/_wsn/page4.html) You might inquire from these guys as to the combo's traits, since they sell both lines; (http://avantgardeaudio.com/index.html) Any high quality SET amp will work well. Keep in mind: Any noise/system shortcomings will be magnified as if by an electron microscope. These speakers are unmerciful in their adherence to the truth.

Best in my experience is the Lamm ML2; others include Art Audio PX-25 and Audiopax 88.

The Lamm is for sure, but in real world don't break the bank money... take a look at the SAP stuff as did Steve Rochlin of Enjoy the Music when reviewing said item.

I own one of these and its' KT66's are pure magic w/ the 2.2 speakers

I'm using an Art Audio Carissa with my Duos and its very good. As a note of interest I also use Van Den Hul Revelation speaker cables which are the best I've tried with these speakers. Very smooth and airy on top. A touch shy in the bass but they're new and break in time should solve this shortcoming.
