Conrad Johnson Premier 140

The Premier 140 is just simply in another class.
No question.
My only caution to you is the fact that thiels (the 3.6 rock!) like power.
Do you have a very very large room ?
Loss of bass is not an issue. It's control. You will experience another diemension in sound !! Very aspect INCLUDING bass.
If you get a chance listen. You may never purchase another (2-channel) power amp again !

I also have the MF2500A and am considering the 140. I am also curious to hear some responses.
