I can't speak to the SQ of the DV60, but; still have the DV50S set up for 5.1 Analog out into a Classe SSP800. The playback of SACD's is superb. All of my 2 Channel listening is with the K-03. Would assume the DV60 would be a step up from the DV50S.

As I understand it, 5.1 audio is available only from the five analog RCA outputs, is that true? I assume the reason the DV60s have depreciated so heavily is because they offer neither Blu-ray nor lossless codecs, and not because they're failure prone.
