I just received and hooked up a Audiophonics LPA-S500NC 500 W X 2 at 4 ohms Hypex Ncoreamp for the L/R channels of my MRX1120 using the pre-cuts. The center, surround and Atmos channels are still being driven by the Anthem. I ran Anthem room compensation to balance the outputs. Since I used the RCA to XLR cables, the L/R speakers were about 4 db down from before as expected. ARC calibration took care of it.
Dynamic range is awesome, from dead silence to 95 db plus crescendos. If I mute the input, I can keep my ear right next to the L/R speakers and I cannot hear any hiss or hum. After three hours of use the amplifier is just warm to the touch. I connected the 12V trigger to the trigger from the Anthem. Worked as expected by turning the Amplifier on when the Anthem turned on. I did not see any of the high frequency shrillness I have read about. I played my stock high dynamic range classical music selections ( Wagner overtures, Mahler symphony #2 first movement and my all time favorite Symphony, #9 from Anton Dvorak). They sound as good as they ever did in my previous dedicated theater room which was a Klipsch set up. Now I have KEF's across the board which is much better suited to my musical interests. I cannot comment on the clipping because that has never been an issue in my system.
For just under $800 and it comes with switchable inputs and a 12V trigger. It looks very well built. The only issue was it shipped with euro style (230V) power cord and 250V, 6 Amp fuse. I replaced it with a standard IEC 3-prong cord and changed the fuse. The company responded promptly to my concern and offered me a credit for the mixup. I plan to take them up on it. I did not open it up and look at the build quality. That is for a future date.
Bottomline so far: Awesome piece of gear which puts out 500W/Channel X 2 from a unit under 8 pounds the size of an elongated shoe box.
