I need help deciding between the following new Onkyo AV Receivers: TX-NR709, TX-NR609, and HT-RC370.
From what I can see the price differs $799, $699, and $499 respectively.
The features are very similar and I'm having trouble deciding whether an extra $300 is worth paying. I have no problem doing it, but not if I'm paying for hyped up features I don't need.
To start, how do I know if I need the extra 10 watts of power/channel from the 709? My 5.1 system will consist of the following:
- Paradigm Millenia 20 Trio as the center, left, and right
- Paradigm AMS 150SQ SM as the rears
- Paradigm PCS 80SQ w/ Paradigm X-300 Amp as the in ceiling sub
Is there a way I can read the specs of the above system and know how many watts of power I'll need?
Secondly, I've heard that the 609 cannot connect other amps for more power. Does this mean the 609 is a "no go" if I get the PCS 80SQ w the X-300 amp. I don't think you can have that in wall sub without the amp. Does this mean I have to go with either the 709 or RC370?
Next, I notice the 609 only has the Audyssey 2EQ, whereas the 709 and RC370 have the Audyssey MultiEQ XT. What makes the MultiEQ XT so much better? I confess, I really don't know too much about Audyssey as this will be my first sound system. For the system I mentioned above would the MultiEQ XT make a noticeable difference over the 2EQ? My living room, where the system will be, is somewhat oddly shaped (modern floor plan with the kitchen somewhat open to the viewing room where the sound would be)..maybe this makes a difference. Because of the openness of the floor plan, the room is a decent size (approx 430 sq ft). Also, it doesn't look like the 2EQ does anything for the sub, whereas the MultiEQ XT does. Any guidance on Audyssey 2EQ vs. MultiEQ XT would be very helpful.
I also notice on the Onkyo website, all of the above receivers are listed as having only one HDMI output. Is this a mistake? From pics of the back it looks like the 709 and RC370 have 2 HDMI outputs? I don't really think this is a big deal for me, as I have no use for a second output now, but it would be nice to know for future expansion. Also, if the second outputs exist, are these independent or simultaneous?
It looks like all three of the receivers support control via IP. I need this for my self built home automation system. Also, it needs to be 2 way (bi-directional); I assume it is. I don't see any need to have RS 232 or IR input (the 709 has these as well).
Finally, I may want to add a second zone down the road. It seems all three receivers support a zone 2. Any better than others on this? Any way for any of them to ever do a zone 3 or zone 4?
Sorry for the long post. Thanks in advance for any advice on the above or anything you think a newbie should consider.
