Try a McCormack DNA-1 and send it back to Steve McCormack for serious upgrade. If you get a good price on the amp, you will even have some change left for additional discs.
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.
