Great review

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?
