Avantgarde - Duo Grosso (I know, a horn in a small room. But I have spoken to many people who think they would fit perfectly in my room and I have always enjoyed the way they sound; albeit a bit romantic. I'm also not in love with the fact that they are powered subs and that I would probably benefit from a tubed amp instead of my uber solid state amp that I love so much).Matt, an additional point to keep in mind, certainly with respect to the Avantgarde speakers and perhaps with some of the others that may have particularly high efficiency, is that the high power capability and high sensitivity provided by your Burmester amps would probably result in your using the volume control on the preamp very close to the bottom of its range. Which depending on the design of the preamp may have a number of adverse consequences.
