Totally unfair comparison here, but just replaced a TX-NR828 that's served faithfully since getting that new when they moved to the 838. Was only using it for the pre\/pro into Emotiva BasX amps, and it was a clean sound, but a bit recessed. In my pattern of buying things as they're at the end of their model life, the replacement is a Yahama CX-A5100. And it sounds about four times as good. Far more present; far more detail in sounds. This is into Emotiva T1 mains, and small Klipsch surrounds, before and after the swap. The only real issue with the Onkyo was a few times in the first years it needed to be reset to defaults and re-programmed because it had lost the output stage -- this back when I was still using its amps. But this Yahama is the first time I've had hi-fi to the level I had become accustomed to back in the 70s running Sansui gear. Maybe it's because Yahama is still a substantial, traditional company, and not the toy of vulture capitalists? Or maybe if I'd gone to the top of the Onkyo\/Integra line I'd have an equivalent impression. Haven't heard that to say.
