I had a quick question here as well. I am coming from an 8 year old Denon 1803 and having a bit of "fun" trying to decide which receiver to proceed with. I had narrowed down my decision to the 708 and 808. I then decided, that between them, the 708 would work great for me, especially since I didn't need to worry for the power so much - I plan on getting an Emotiva next year.
This morning I noticed a great deal on the RC270 that would add a good bit towards my amp fund if I went with this over the 708. Going back and forth between the two, the main benefits of the 708 over the RC270 were:
-Sirius radio (don't have it and don't plan on getting it anytime soon)
-10 watt diff (should not really matter since I plan on upgrading to a separate amp)
-1 more hdmi (I don't have nearly enough inputs for this to matter)
-12v trigger (zone 2)
Of all the above, the 12v trigger and RS-232 are the only ones that I don't know too much about. I know the 12v trigger is used to turn on items - what is meant by being zone 2? What use is the RS-232? This I know nothing about.
Thanks for any help!
