IMO there are VERY FEW receivers for under $1000 that have a power supply and amplifiers adequate to properly drive 7 channels of REAL speakers.
Actually, the ONLY one that I know of is the Denon 3312, which I have seen for as low as $850. If you want the VERY best, the Cambridge 651R and 751R are without equal in sound quality and REAL power to drive REAL (low-impedance) speakers.
Everyone rates their stuff to drive 8-ohm speakers, because that is what the 50-year-old FTC regulations require, ignoring the fact that TRUE 8-ohm speakers are almost non-existent anymore. The REAL question is...what receiver can drive 5 or 7 4-ohm speakers well?
The LOWEST IMPEDANCE of a speaker at ANY FREQUENCY is what really counts, and it is hard to find a speaker that isn't under 5 ohms at some frequencies. That is the REAL LOAD the amplifier has to deal with.
Almost every speaker that is labelled "8 ohms" by the manufacturer is NOT really 8 ohms. Those ratings are worthless nonsense.
To find out the real impedance of a speaker, you need to ferret out the GRAPH of impedance vs frequency for the audio band.
The idea that you can get something with the kind of power supply and amplifiers to properly drive 5 or 7 channels for under $700 is ridiculous; a decent stand-alone 2-channel amplifier costs over $1000.
It is like asking which car you can buy for $10,000 that can win the Indianapolis 500.
Personally, I think the very idea of more than 7 channels is extreme stupidity. Where is the program material that HAS more than 7 channels?
If the source program materials do not exist, then what is the point? Duhhhhh.
