We watched 30 Days of Night on BR DTS HD MA with the 1500-3 connected to the M100s and 160. My Onk was at -25 and I didn't feel like I was missing anything. The 1500 performed remarkably well. Transients were sharp, sudden and truly startling. Images and soundstage didn't leave me wanting for anything more.

At -25, I have more than 35dB of headroom. The 1500 is too much amp for me in the living room and it may be too much amp for my 4,200 cu.ft. space. I'll have to compare with the 1000 and more A/V sources and material.
