New Anthem AVM 70 and MRX 740 difference in processing

@t-mac thanks for your input.  I'm primarily 2 channel too, but I have another system for that, so I'm not worried about the 2 channel ability of the receiver/processor.

I'm sure I'd be "fine" with the receiver but @soix acts like there would be a major difference so I'm still torn.

To be clear, given the level of your system I think you’d be fine with the MRX520 or the RX-A2080, and again I’d recommend you save 1000 bucks and get the Yammy.  The problem was you implying the AVPs are way overpriced and may be just repackaged AVRs minus the amps without any credible evidence.  If you’re gonna suggest something like that here you should provide facts and not hearsay from a couple dudes on some crappy website.  Peace out. 

If I had credible evidence I wouldn't have asked the question.  I would go denigrate other posters without providing evidence - as you have done. 

I'm looking/searching for credible evidence one way or the other.  That's what a forum is for.

Ah, the old “I’m rubber you’re glue” defense.  Good one, in third grade.  I’ve denigrated no one — just merely pointed out inconsistencies and unfounded statements while trying to stop you from unnecessarily wasting $$$.  Guilty, but I can see how someone with insecurities and limited knowledge could interpret that as denigrating.  Learning is sometimes painful. 

I think the Anthem 520 would drive the rear speakers.  It should be easy enough to insert the 520 as a Preamp, then reattach the speakers to the 520 and do some comparisons.  If you have an Anthem Dealer that will let you borrow the MX 520 for a weekend that would be ideal.  Rears ideally should be for ambiance only in music.
If you can’t demo, then just get the 520 and if you find the power section inadequate for the rears just use the 520 as a preamp.  Most of the improvement will come from the RC, and you don’t need the processor for that as it is the same software in the AVR
