New Anthem AVM 70 and MRX 740 difference in processing


I've had my eye on the new Anthem line-up recently. But I'm torn between the AVM70 processor only vs the MRX740 receiver.  

The receiver offers pre outs for all the channels I'd need.  So I wouldn't really use the amps in the receiver. 

BUT, MRX 's resell is going to be much better because it's all-in-one - fewer demand for the AVM, and the AVM is $1000 more.

So, are the internals of the AVM really all that much better? And how much difference would you really notice on multichannel movie playback?

Thoughts on this?

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
@soix that wasn’t a defense. It was a response. Read the first sentence again.. If I had credible evidence to the answer then why do you suppose I would post this topic in the first place? 
I've researched the Anthem products and from what I've read, the Pre-Pro has a better power supply and much better DAC's than the receivers.
I'm sure you could tell a difference, especially in 2-ch listening.  
But since you have a dedicated 2-ch system, I would probably just go with the receiver and be done with it.

Also, some manufacturers (I believe) use the same internals in their receivers as they do their processors.
That’s a statement, not a question.  It’s negative, ignorant, and accusatory.  A question would be: “Do some manufacturers use the same parts in the prepro sections of their AVRs in their AVPs?”  That’s a worthwhile and legitimate question while yours is just a completely uninformed, pigheaded statement.  See the difference?

Well, I said "I believe" meaning I didn't claim to know the absolute answer.  Came here looking for more information that could sway me either way. 

This all coming from a guy who recently asked if an iPhone/iPad is a good streamer source.  Admitting he didn't know the answer and was looking for confirmation.  Which by nature accuses manufacturers like Lumin, Auralic, PS Audio, Mytek, etc of ripping off the market and uncapable of making a streamer better than an iPhone. 

Take a hike.
