OK, just hooked up the Marantz NR1501 into my HT as a replacement for a burnt Panny SA-XR70. Very nice receiver--I really like the way it handles MP3s..very musical. Prior Panny-based system was quiet (no pops). With the Marantz, occasional light popping in all speakers (not at once), just enough to annoy. Popping starts after 45 minutes to an hour of play and only on HDMI connected devices--TV and DVD. I re-wired the speaker cables to the back (direct connections, no binding posts) , but that did not eliminate the issue. The receiver is well ventilated I believe, in an open cabinet with about 8 inches of vertical clearance.. Just wondering if anyone else has experienced this. I purchased this receiver used off E-bay and am now wondering if its defective?
