as a aerial owner (10-t's) i can recommend the krell fpb-200 like the poster above. my room is 14x25x8 and it more than does the job. you will get the bass control you seek and slam. of course only if you get it used or a great deal.
Amplifier suggestions
I am using Sony DVP-S7700 as Transport to Theta Casa Nova to Aerial 7B. I would like some suggestions in the $3000.00, (used), range for amplifier. My room is 15'X30'X9' ceilings and I listen to Jazz, Blues and Rock at high volume levels. The Aerial's need an amp with good bass control and high power output. Thanks in advance.
