For a little more, there was a nice pair of Duos on this site a couple days ago.
I have the Duos and they are very revealing of everything, from AC line noise to colorations in the equipment up stream.
The Duos will shine with the right system behind it- you certainly don't need a 50 watt amp to drive them, and without being familiar with the sonics of the amp you have, it may not be the right choice.
The active aspect of the AvG is the woofer, which to me, is the weakest part of the speaker. The midrange horn, hooked up directly to the amp (and jumping from there) has startling clarity, detail and image, due in part to no crossover. Good luck.
