Anthem MRX 740 8K as an upgrade to my Denon AVR-X3700H

I have a 7.2 system.  I drive my front speakers using pre-out to my 2 channel system amp that drives my 2 channel system speakers.  I have 2 more sets of floorstanders for side and rear.  2 self powered subs.  Pretty happy with the system. 

Thinking of the upgrade in the subject.  I'm much more well versed in 2 channel sound than AV systems and would appreciate comments. 

I like the same things in theatre however, clear, accurate, and powerful, and dynamic.

For a streamer, are there better options than my LG smart TV delivered to my HT receiver via ARC?  I don't see any discussion of HT specific streamers/decoders.  



Just to be clear, I am looking for a reciever for HT only.  Nothing to do with 2 channel music.


Well , I misread your need's description  .

I thought you were looking at HT Receiver that was also  very good for 2 channel music.         

My bad .



@erik_squires continuing to do some more research with your suggestion of Marantz, I'm leaning toward the Cinema 50 which seems to fit my system perfectly.  If also has Dirac Live Room correction capability which should be an upgrade.  Do you recommend Dirac Live?  

All of this said. I'm continuing to be impressed by my simple, and several years old, Denon AVR-x3700h as I watch movies.



@carlsbad2 Of the few DiracLive curves I've seen they look really good and some versions also let you set your own target curves.
