I really like my Rz830 but I've only had it six months so I can't comment on its longevity. It has a nice aluminum face-plate and the volume knob has some mass and excellent feel. It feels quite high end. I had an HDMI board fail on an older Onkyo Pre-Pro (885) but it might have been lightning as the same thing happened to my Anthem a year or so later.
