I just bought the NR-5007 and find it sufficiently powerful in my home theater (3000 cubic feet) to power the M80s, the VP150, and my four QS-4s without the need of any external amplifier, even though I run them as large speakers, with a cutoff of 40Hz, letting the HRS-10 handle everything from 20-40Hz. I tried playing the system at THX reference level (0db) but it was far too loud for my ears (even though it had no audible distortion!) so I now usually set it at
-10db to -15db, depending on the source.
