Laughing...KR you should be able to lift 100-lb speakers w/o difficulty. Great review!

Sure I can.  However, the next day my lower back tells me that I shouldn't have.

Good to see the little brother getting some love. I auditioned these a few months ago, and thought they sounded fantastic, even in pretty poor conditions. I was really impressed by the quality and quantity of bass produced by those two small woofers. Though I am sure they cannot compete with the 800s, they held their own (sans subwoofer) in the low frequencies against some lesser tower + powered sub combos to which I compared them, and they handily beat those combos across the rest of the frequency range.

Kal, any notable differences in sound when driven by the McIntosh amp vs. the Halo?

Not much.  They were a very little bit more forward in the mids with the Mac.

The B&Ws sure sound as tubby as I remember them in this comparison to the quarter-the-price JBL Studio 580s:
- cued to the beginning of a telling recording. The JBL equivalent starts at 11:43
I get the feeling that there is no-one at B&W who knows how to design a good sounding box for bass - they sure make them look good and sell, though, and I suppose that has to be the bottom line but, thankfully, not for me.
