I am in agreement that in general avr reliabilty has gone down. Onkyo pissed me off too so all i can do is try something else next time like yamaha. I like the sound of keeping tighter controls in your own mfg plant. I got an avr-473 to see if their HDMI woes are anything like onkyo. Overall i liked onkyo but reliability is a big deal for me as i rarely buy new or buy extended warranties.
Stellar customer service is worth its weight in gold. If Polk sold AVRs id buy one from them or L.L Bean.
