My favorite Home Theater receiver of all time is the Onkyo TX-DS939. This thing was a beast in every way. It had over 100 watts for all five channels and was emensly powerful and also THX Certified (one of the first to do it). I absolutely loved the bottom separate hidden screen. The volume knob was also motorized and solid. At it's introduction the 939 was the best Home Theater receiver in the world. It could hold its own against many separate components too. At the time the rear panel connections were seemingly endless. Every AV or Audio input \/ output that you could ever want was there. It was one of the first to have included a self calibration mic for speaker setup. Even today there has never been so much packed into a receiver with a solid build quality as the 939. It was truly ground breaking for it's time.
