No, never get a receiver..... The power amp sections should be separate, not in the same box for an audiophile experience, i.e., if you also plan to listen to music with it.
Get a Surround Preamp Processor such as the Marantz AV10 (there are no amplifiers built into it!!!).

Thereafter, get any number of power amplifiers for how many ever speakers you’ve got.
For example, here is a decent Multichannel Power Amplifier.
ATI 6600 signature series series, 300Watts @ 8 ohms, 450 Watts @ 4ohms all channels driven.... Since you can get these with any number of channels ranging from 2 to 7, you could probably get one 3 channel amplifier for the front stage and a second amp with however many channels you need for the remaining channels (surrounds, back surrounds, heights, etc).

Other cheaper multichannel power amplifier options could be the bigger Class AB Rotels, Parasound, Monoliths, etc.
You could also use any of the hifi 2 channel high end amplifiers you prefer for your surround rig, but, the latter approach could get quite expensive.
