EAD powermaster 2000 can be had used for a little over your stated price. Effortless, musical, with tight, deep bass. Can handle 1 ohm loads with ease. Provides 400 watts into 8 ohms x five channels with all channels driven. With dynamic energy steering (using a single 3 horsepower toroidal transformer) can be used as a stereo amp with resultant potential for 1000 watts per channel into 8 ohms! Beautiful cosmetics are icing on the cake.
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.
