Looking for some advice here please,
I pulled the trigger on a pair of Polk RTi-A9's at a nice sale price. Been fighting the upgrade bug for a long time and finally gave in. So my question is.
I'm using an old Yamaha HT-6080 and powering everything with an XPA-5. The new Polk's are rated 500W, so I'm wondering what's the best way to connect them. Is there any benefit in running just the fronts with the XPA-5, separating the two binding posts for the mids and highs on the new sides using four channels and one for the center. And use my receiver to power my rears. Or just hook everything up as I have it now with each channel to each speaker? I know its not bi-amping but im wondering if i'll get more out of them this way? Any advice would be appreciated.

Use the XPA5s 5 channels. Sell or use the Yamaha in a less critical listening environment. The Emotiva is just that much better

^+1. Let the XPA-5 run all five channels. Using two channels from the same amp to drive one speaker won't get you much, if anything.

Great, thanks for the advice. You read so many conflicting opinions out there. Assumed that was the case.

I just sold my RTi-A9's and they were Bi-wired from a Gen1 XPA-2 and sounded great. BUT.... got a great deal on these Wharfedale Opus 2-3's and everything blew up from there... Now an XPR-2 is on its way.
Good luck!

Interesting it has been one, or the other. Of you plan to use the XPA-5 as amplification you would require a Preamplifier Processor ahead of it. Especially if the Yamaha does not have Preamplifier outputs, or your plan to use say the XMC-1.
The XPA-5 is a great amplifier, and will give you lots of music and theatrical enjoyment no end.

As far as wiring, basically anything you want really. Budget and application rule. RCA shielded cables, and a decent gauge quality speaker wire are all you need. Emotiva sells some good cables here for your enjoyment. Others are Monoprice, Blue Jean cable Just to name two. It is easy to get caught up in the cable race, and blow allot of money away. Plenty of discussions here in the forums on what makes sense, and less. Be sure to check them out. Enjoy!
P.s. Avoid over paying for HDMI cables. The only time they'll cost more is for very long runs. Key points are the connectors, and shielding mostly.

Thanks for the reply's. Just to clarify in case I didn't explain myself clear. My audio source is the yamaha amp. It has pro outs running to my xpa5 with each channel powering each speaker. I'm currently running rtia7's for my fronts and a csia6 center with some a1's for surrounds.
Everything's been running great, have adequate speaker cables and nice sound. (To my ears anyway) Upgrading to the A9's just left me wondering if the 200w xpa5 would give me good power to the 500w rated speakers. I had read elsewhere that a few people had got what they feel are good results running a separate channel to the lower mid binding posts and a separate channel to the higher binding posts with the binding post jumpers removed.I'm assuming in the theory that splitting the load between the lower mids and the upper highs will help. No idea if that's the case or not, but I have the channels and extra wire lying around if it is a viable option to try. The yamaha wouldn't have a problem powering just the two rear channels speakers. But again if it's not really useful I have no need to do it. Just curious if it was worthwhile to get a couple of splitter cables to split the two side pre out signals into the amp.

I have my 3 front definitives bi-wired. They sound is slightly more open with a pleasing result. I tried bi-amping same speakers at a friends house with a Yamaha (140 watts X 7 reciever) and we both agreed it was not worth it with minimal, if any improvement. The best results I obtained was upgrading the 7 channel amplifier (200 watts per @ 8 ohms, all channels driven, etc.). Totally worth every penny.

I'm running the same front soundstage as you are, I'm Bi-Amping my front 3 with my XPA's and my AVR with some pretty pleasing results, XPA's for the Mids and AVR for the Highs, since the tweeters use so much less power it works out just fine. Just thought I'd mention it, if you like experimenting. I have my 3 front definitives bi-wired. They sound is slightly more open with a pleasing result.
