Just for discussion sake, the AV7705's THD+N is about 0.01%, which is NOT audible.\n\nThe 3dB down at 20 kHz is not audible either since most of us can't even hear beyond 18kHz. Also, a Frequency Response deviation of +\/- 3.0dB is considered normal for SPEAKERS. So even if the AVP\/AVP is ruler flat at 20kHz or 30kHz, your speakers will not be flat.\n\nThe question is NOT SOUND QUALITY. These components can all sound great.\n\nThe salient question is - Is the Marantz AVP with the THD+N of 0.01% and a -3dB at 20kHz LESS RELIABLE than the Denon and Marantz AVR's that measure better? :D\n\nRight!, Gene's findings on Yamaha's RX-A6A wasn't what he expected to find. What was it, one or two surround channels had like 65db? Still not audible. But paying over 2k for a AVR or Pre-Pro one expects more I guess.\nWhat am I missing here? Seems a lil lite? Not knocking EMOs BasX Pre-Pro. $999.00 for 13 channels ain't bad at all though.
