Summary: I get the feeling that the reviewers that had difficulty with this receiver were either not reading and following the manual or really just did not understand what they were doing. I've had the machine for just over 2 months, and it performs great.
Summary: Don't be fooled here by reviewers that don't read the manual! This is an AWESOME amp! Using with JBL studio front, center and powered subwoofer, Audiosource 100 watt in-wall speakers. This amp powers them all with ease. I can't turn the amp volume all the way up, it's so loud, it hurts!
Summary: For a semi-serious home theater enthusiast I have been extremely pleased with the AVR520. I switched to this reciever from an old Pioneer Elite VSX-97 and seriously consided another Pioneer Elite, Denon and Integra AVR's but found the sonic clarity unsurpassed by any of the other models.
Summary: I was thrilled by the performance of my 520 when I first got it. I was powering some relatively efficient energy eXL 26 towers and they sounded great. However, I recently upgraded to the Veritas 2.4 from Energy and the 520 doesn't even come close to providing enough power for these speakers.
Summary: I don't like this amp at all, there are so many quirks. If you want to isolate the narrative audio during a movie and pump up the center speaker so not to wake your neighbors, you'll find that even with the DTS light on, all the tracks will become louder via the center speaker.
Summary: I am extremely pleased with the rich, clear sound of my 520 receiver. DVD with optical cable is absolutely great. I had limited experience in home theater. So the setup was one step at a time; first the Denon speakers, tried the FM (very good), the Phillips DVD870P came next with optical out, then...
