Both of these demo'd very well with my Aerial 8'B speakers. I went through this exact search a couple of months ago with my EAD Ovation and DV-09. You have a couple more options though which are the EAD amps (any of them are enough power) Also and I am serious, the Sunfire CinemaGrand Signature. I know the build quality in not in the same league but just try it side by side with each of the other amps and you will surprised as I was. I was even looking at the Proceed combo for 8 grand and just could'nt go that rout along with the others when the Sunfire is more powerful and musical although a little colored. The EAD amps are of the same quality if not better and cost less than the Theta and Classe- The EAD amps sound as close as possable ( I can not tell the differecne) to the Stereo MarkLevenson anps if you like that kind of sound.
