Yep, I've heard 'em, and yes, they are superb. I have a fairly strong prejudice towards tube equipment (even though I don't own tube power amps), but these just got the sound right. Really right.
I haven't been THAT impressed with the other Rowland gear, although it's all good. But these were something else, and they were, at least to my ears, noticably more real than the 302 that I'd heard previously.
One thing that nobody's mentioned yet is that they run COOL. As in cool to the touch. At full power. All day. My *preamp* puts out 3-4 times as much heat as a pair of the Rowlands, forget the power amps. If your monoblocks heat up your room unpleasantly during the summer, go audition these 201s!
And no, I don't own any Rowland gear at all. I'm just impressed.
