Denon 3805 v. Onkyo tx-nr900
Alright guys. I'm driving a 7.1 Polk Lsi setup.
LSi 25 mains
LSi Center
LSi FX sides
LSi 9 Rears
I use my system for both music and movies. The two things holding the Onkyo afloat are THX & Neptune. On the Denon auto room calibration works nice, video upconversion a plus. Just wondering if anyone else had some opinions for me on these two recievers?

I don't really think either of those receivers is going to have quite enough power to drive that setup.

I would post this question on the Polk forum.

Am I crazy? I can not find "the Polk forum" on this website. I know hometheaterspot has manufacturer forums... where are they on this forum?

Hey Jason,
Good choice of speakers and receivers to drive them. Both receivers are advanced in their surround sound processing and have ample power to push the woofers in any of those speakers you listed.
The Polk LSi25's are an excellent foundation to a home theater system especially because they feature a built in 10" powered subwoofer. The only drivers that the receiver will have to power are the dual 5.25" woofers and the a 1" tweeter. That I would say is not a tremendous driving requirement.
The rest of the speaker requirements (C, and Rears) are also equally as easy to drive as the LSi25's.
I would pick the Denon since it has a advanced Room Correction, Bass Management, and other features. I do think however that the Onkyo sounds better, a little more on the warm side of the spectrum. The Denon is a little on brighter side of things.

I was in the same situation just about two months ago. I was looking at the same two receivers you're looking at now. IMO, both receivers have plenty of power to drive any speaker setup for home theater. For the kind of money they go for, they HAD better be powerful enough.
I was going to go for the Denon because it's a newer model than the Onkyo and has some other features that the Onkyo doesn't. But I decided to go with the Onkyo because I had a deal I couldn't pass up (only $950 - tax included & full warranty). I figured that I could live without the features on the Denon that the Onkyo doesn't have and saved a couple hundred bucks.
Both are nice receivers. You wouldn't go wrong with either one.

I agree with John, based on the published specs., at least get a 2 channel 4 ohm capable power amp to drive the mains. Between the two, Denon seems to be a more popular choice for Polk users.

Both of these receivers will have very good processing, but these speakers will dip very low in impedance, I would DEFINITELY go with external amplification for some or all, or a better receiver for these speakers. I would not call these speakers "easy" to drive, powered subs (25s) or not.
