It seems that a lot of receivers that I've looked into have a power rating of so many watts per channel at 8Ohms each. But have a "Dynamic power rating" at varying Impedance rating. So my question is would it sensible to have all my speakers rated at 8Ohms each? Or does it entirely matter?

See specs on this receiver for example. http://ca.yamaha.com/en/products/audio-visual/av-receivers-amps/rxv-series/rx-v571_black__u/

As long as your speaker's nominal impedance is within the AVR's specs you'll have no issues.

Choose speakers based on their sound.

Yes, with this (and most lower/mid level) model you would be better served with 8-ohm speakers, although per the Owner's manual the model is designed to work with 6-ohm or 8-ohm speakers.

With many (most) receivers, if you choose 4 ohm nominal impedance speakers, you will need an external amp (make sure your receiver has pre-outs).

I have a Yamaha 180 and tech support told me only the FR/FL could handle low impedance speakers.

Well the speakers I have are 8Ohms so I don't think I need to worry too much. I was just curious more then anything I think.
