This is what I found interesting. I was in the front row and saw the clip indicators on the Bryston 28B 1000 wpc monoblocks light up. I used to have Bryston 7B St monoblocks on B&W 801's and never clipped them. The 28B's have an enourmous amount of power. I really don't see anyone driving them with 28's.
Maybe good candidates for Class D amps? Though those didn't work well with my friend's 20.1's. The other thing to note in considering this very relevant observation was that the demonstration was in a pretty large room with high ceilings and wall-to-wall carpet, and the music was being played at fairly realistic levels (at least in our session). They may do a bit better in a more moderately sized and lively room. Good point.
