Anthem MRX 720 Question

I want to improve the sound quality of my system and am looking at new receivers.  I have a 5.1 system with Paradigm S3's for L&R, a C3 center (LCR all V3), dual Klipsch subs and Sonance surrounds.

A fair number of people rate the Anthem 520, 720 and 1120 receivers highly for their sound and room correction software.  I'm getting close to pulling the trigger on a 720 but have a concern.

Many of the forums talk about HDMI connectivity, receiver lockup, firmware and various other issues.  To be fair, it seems like those discussions dropped off in recent months presumably as newer firmware became available.  

Does anyone have recent experience with the 720 they can share?  Have the HDMI, receiver lock-up and PlayFi issues been resolved?  Were those issues unfairly highlighted?  A demanding forum audience could make something appear bigger than it is.

I'm replacing a Yamaha RX-A3050.   With the current setup if I select FIOS, ROKU, BluRay, Spotify, Chromecast etc from the Harmony remote, a lot of activities happen behind the scenes; devices power up or down, inputs are selected, amps and fans turn on - and it all works every time even when I switch between activities.  Yamaha's switching is impressive since it rarely has HDMI/HDCP handshaking issues.  I love that since recovering from those issues usually involves recycling the power to the receiver, TV and/or device.

I want good sound but don't want to lose the reliability and ease of use I currently have. I'd really appreciate hearing what others have experienced with their Anthems.

Thanks in advance.
