OK. Here's what I did today on my Denon...Crossed F/R 60hz and 80hz and setted RESTORER to OFF and My M80 sound so magically dynamic in Pure/DIRECT mode. I can push the Denon to -12dB without getting NO DISTORTION and SHUTDOWN problem. This was done with lots of listen in hip hop/pop/rap most with heavy bass.
With RESTORER to HG mode I can see my XPA 2 LED meter hit up to 10 lights. Restorer to OFF, it drops to 7-8 lights. Gmeyer - Could be what you stated that I push my Denon too hard to the MAX. Also, my SPL read at the highest point I recorded was 115. MAN the M80 sound so amazing. My normal listen SPL is around 80-91.
