I'm needing help in trying to figure out which avr would power some new speakers and also run a Zone 2. I don't know how to determine if a certain avr has enough power for certain speakers. Since I haven't finalized my decision on speakers yet, I thought if I gave the specs of the speakers that have the lowest nominal impedance and lowest nominal sensitivity, that would suffice. The L/C/R average 6ohms impedance and 86db sensitivity, a powered sub and 2 back speakers at 8 ohms/ 88dB.

The 3 avr's I was looking at were: Denon 1713, Denon 2113ci & Marantz SR-5007.

I'm trying to run a 5.1 system in the family room and then a Zone 2 - 2.0 outside on patio. Am I right in assuming that I would need an external amp to make zone 2 completely seperate from the 5.1 system, in all 3 receivers? If I hooked up the patio speakers to the last 2 channels, in the 2113ci & 5007, I could then power it them but the content would be the same as the 5.1?

Sources: Directv DVR, XBox 360, BluRay and would like to play my itune playlist on my computer through an ipad.

Any of these AVRs would serve you well although the 1713 being only a 5.1 AVR would require an external 2CH amp to power the Zone 2 speakers, while both the 2113CI and 5007 as 7.1 AVRs could use the Surr Back/Amp Assign speaker posts to power the Zone 2 speakers. You could play either the same source or a different source in Zone 2 with limitations as noted in the post below ....

Thanks for the reply. Are you saying that with the 7.1 avrs I could play, say, music from my itune playlist on Zone 2 while watching a movie in the 5.1 system? I kind of understand the limitations, but not sure how I would get the playlists, from ipad, to play in Zone 2 with an analog connection.

Correct. Different sources in each zone noting that "network" sources (eg. Airplay, Pandora, internet radio) will also pass to Zone 2. So then with the iPad you could use Airplay to stream the audio to the AVR (main zone and/or Zone 2) using your home's WiFi router or you could connect via USB or with a 3.5mm to RCA cable. All of these connections will pass to Zone 2.

Thank you very much for the explanation. It's funny how much wrong information you get from sales people at retail stores. With that set up, would it also be possible to add a Zone 3 with the Zone 2 pre-outs, to say the kitchen or even 2 rooms (content being the same)? I understand this would need the external amp if possible. Any suggestions on what external amp would work. Thanks again.

Yup .. you could even add a few more zones using a 4-zone impedance matching speaker selector connected to the 2CH external amp.

Perfect. I really appreciate the time you spent for your replys. I think I'll probably get the 2113ci. I want the 7.1 but don't think I need to spend the extra $200 on the Marantz. I'm leaning towards the Wharfedale 10.1 or 10.2's, plus the matching center. I'll head over to the sub-woofer section to get suggestions for the sub. Thanks again jd.
