I have used this amp in the past for my B&W 803 Series II until I upgraded to the EX 4420M monoblocks. This amp sounded clean, transparent,lots of air and very tube like. The sounstage though not as deep and wide as the mono's seems to outclass any brand in its price category. Presently I'am using the EX4420 stereo amp for my dual center speakers B&W HTM (one on top of my Toshiba D80F90 rear projection TV and the other right below the screen). The dialogue seems crispier, clearer and more focused. It has enough power to render to difficult passages. I think that using B&K amps, well you cannot go wrong. I'am just waiting for my monoblocks to be delivered because they're being serviced for bias check-up. Then I will tell more about the EX4420. For the value to performance rating I give a 5 star.

This amp is very tube-like, transparent as well and holds tight on the lows. I used to have it drive My B&W 803 Series II Speakers and was doing very well until I got a pair of the monoblock version.

I couldn't ask for more from this amp. I even had a side by side comparison with Adcom 5800 and Acurus A200 and found that the B&K sounded more airy, more detailed and wider and deeper sound stage and best of all less harsh. It's really tube-like, perhaps it carries the B&K signature sound all the time.

Now my EX4420 drives a pair of B&W HTM center speakers (one on top of my Projection TV and the other below it). It satisfied everybody who have heard it and I think it will stay with me for a long time.

Awesome piece, would recommend Vs. any other amp,"in 2-3K price range" see my review of the Proceed AMP2. I bought the B&K.
