revel m22 or f 30's

I have an opportunity to get either the m22s or the f30s. I had an opportunity to hear to hear the m22 and the f32s but not the 30s' Any diff between the 32 and 30s ?

Also, what would be be a good source to pair any of the above with ? My local dealer recommended the Arcam AVR 300.

Thanks for your help.
