OK, so I'm pulling my hair out trying to decide between these two. I actually already own the TX-NR809 and I love it. It's in use in my music room, running in a 2.2 setup (plan to make it 7.2 some time next year). But now I'm setting up a 5.1 system in the living room, and can't decide if I want the same receiver or if I should go with the Pioneer SC-1222-K. The only reason I'm having a tough time is because I had the Onkyo in the same cabinet I will be putting the new receiver into, and it got very warm in there, even when it was just in HDMI standby mode. I want to be able to close up the glass doors on the cabinet when the receiver is in HDMI standby mode, and not cause any damage to it. Right now, I have my current TX-NR809 sitting on a stand out in the open, and it stays nice and cool that way. I read that the Pioneer runs very cool to begin with, and while the unit is on, I don't mind keeping the glass doors open.
So my questions are:
1. If I went with another TX-NR809, will the heat build up from staying in HDMI standby mode cause any damage to it? I don't remember the exact temp it built up to, but it was enough to where I felt uncomfortable about leaving it that way. I really don't want to start cutting into the cabinet to install fans either.
2. If it's too risky to leave the TX-NR809 that way, how does the SC-1222-K compare to it? I've read a lot of great things, and one of them is that it runs very cool. I was concerned about the Audyssey vs MCACC and that you cannot adjust individual crossovers per speaker. My rear channel speakers can't go down as low as the front and center channels, and I would hate to loose performance in that aspect. Everything else seems comparable.
Any comments or suggestions would be greatly appreciated! Thanks in advance!!
