Amplifier for Avantgarde Duos

I've owned the Duos before and 300b amps work wonderfully with them. I suggest the Sophia 300b as first choice for best value. The Wavac is excellent. The Cary SE Signature did a nice job too. The ceramic base Sophia Electric 300b tubes I'd recommend with all listed....I like them better then WE's! I'd avoid the Wavelength models though.
GREAT speakers! Good luck and Good Listening!

Hi Chris- Since I know you are at least contemplating a switch to a 300B based amp- Here is a link to a review of 11 different iterations/brands. You may find the observations/info helpful: (http://www.stereophile.com/features/229/index.html)

I have a pair of Unos which sound excellent with a Art Audio Diavolo.The amp is also dead silent.

What cables do you have? It's possible a change in cabling may be a cheaper alternative. A warmer cable such as Cardas,Purist,Audience,Transparent,MIT would do the trick.

I owned the Duos for about 3 years and I thought they far and away sounded best with the Audiopax 88 mono amps. I owned the BAT VK150SEs and used them on the Duos which to my ear was not a great combo, but I guess others disagree since they did show with them on the Trios a few years back, but then I didn't like the sound of that system either. One nice thing about the Audiopax amps is that the tubes are cheap and the sound warms up really quick.
