@melchionda I recently purchased an Anthem MRK 540 8K...Please hear me out.
The Anthem has far exceeded my expectations as I was considering an Onkyo RZ50 etc however I have a 5.2 room that really cannot accept much more so I did not need the additional channel inputs. The Anthem actually does music incredibly well to my surprise and keep in mind the power rating for the Anthem are WPC all main channels driven not just 2 (in my case 5 channels all getting killer 100 watts). Now for the elephant in the room software set up issues,yes I too struggled with the setup because the instructions are not clear ,long story short run Chromecast or airplay first and your unit will connect if wireless,In a wired setup you will have not problems. And my unit makes ZERO fan noise even after an afternoon of big boom movies.I used the 540 8K for the first week without implementing the ARC Genesis room correction and was impressed with the unit out of the box.When I ran the ARC room correction OMG what a difference everything opened up and it made full use of the power on tap to its fullest. (ARC does give the bass a leaner presentation but simply increase the sub(s) gain by a tad in my case).
I’d suggest my units big brother(s) in your case.Buy it from Crutchfield (don’t like send it back Hassle free) try the anthem alone without any additional amps first. I suspect you’ll find you will not need any additional amplification .I cannot crank my MRX 540 8k beyond 35% without discomfort the detail,bass slam in movies & music its all there you cannot do better than an Anthem witout spending crazy money,it truly is a complete package and all that!
