Better B&K amp?

The EX 442 is the better amp. It can handle lower impedance loads better, has better stereo seperation and it's DC coupling should improve upon the mushy bass response of the lesser B&K amps.

I had my ST-202 Modified to have a DC Coupling cicuit,newer Risistor\Caps installed,Star Grounding and re-wiring.Plus having the BIAS turned up to run higher Class A!That is the best of it and it is a totally different Amp!Same Transistors though!
He could opt to get a modified ST-202 also!

Your in the right camp, i run B&K M-200 monos with a Conrad Johnson Premier 3, awsome.

I own lot of B&K amps and preamps. ST1400 2x105rms,AV6.5.4 6x60rms,2pcs-TX4430THX 3x200rms and 2pcs-AVP300THX, all are excellent performers especially in music.I guess EX4420 dual mono would be much better choice as I enjoyed much of what I got.

I own a B&K Reference 200.2 S2 amp, which is their current production amp. This thing never runs out of power and is very quiet. It only have a couple of inches above it to breath and yet it still hardly gets warm. With a new tube preamp, I would actually begin to make comparisons between this amp and tube amps. Nothing but smooth music at all volumes. The bass on this amp is very impressive. No subwoofer required even on music that would normally need it. I am powering a pair of Dali Ikon 6's with it. I have however powered many other pairs of speakers with it. As others have said, I would keep this amp even if I bought something better. Hope this helps
