i owned the b&k for a long time before selling it on impulse to get a denon avr--big mistake. the b&k sounded fantastic on movies and esp. on music, was bulletproof and had the best learning remote i've ever used. it doesn't have the numerous, largely useless dsps and listening modes of the mass market ilk, which i never minded since i rarely use anything but dts and straight stereo.
as for the nad, i haven't owned the t763, though i've owned lots of their other amps/combo players with mixed success--like english cars, nad is well-engineered but unreliable w/lots of ergonomic quirks. i always felt their amps were powerful-sounding but somewhat colored and forward-sounding, whereas the b&k is very natural and neutral. again, i haven't heard the t763.
i assume you can get the 202, which is an older product, for around $300, which would seem to make it a no-brainer.
