If you found this thread because you are searching for information on the Onkyo TX-NR708, I have copied below the review I posted on Amazon.com, just in case you either didn't read it there or overlooked it there.
I'm posting this so you don't have the same experience I'm having.
"Unfortunately for me and many others who purchased the Onkyo TX-NR708, the bad reviews weren't around in 2010. I, like many others, purchased mine in the last quarter of 2010, and the bad reviews started popping up in April 2011. At first I thought, "Mine lasted more than 4 months, so maybe there are just lemons out there and mine isn't one of them." Wrong - mine took 5 months to go crazy.
I've never seen anything quite like it... At first, while playing an SACD hybrid from the local library, the Onkyo switched from DSD mode to PLII Music. I thought that perhaps the disc was scratched in a way that made the SACD layer unplayable, so the player somehow automatically switched to the CD layer (I don't even know if players are capable of making this kind of adjustment). So I threw in an SACD that I knew had no scratches, and suddenly the Onkyo went "listening mode crazy". It just started scrolling through the modes uncontrollably. I had to wait for a momentary pause to either turn off the Onkyo or go to setup mode, but once in setup mode the uncontrollable scrolling began again.
I consulted the manual and did a factory reset, but this made no difference. So today I'm off to the closest service center - 60 miles away - and wondering what recourse I have. Do I keep bringing this thing in for service every 5 months, or just cut my losses and buy a different unit? Is a class action suit in the works? "
