The avr from the old HTIB 9300 set....Onkyo did put decent avrs in those sets, tho that's the lowest edition of Audyssey. I have an HT-RC370 which isn't too different, altho has Audyssey XT instead, use it in my bedroom setup. The only complaint with that unit I've had was when it had the hdmi/network board failure, but performance wise it's been fine.
