Thank you for your responses gentlemen.
I couldn't find any threads for a direct comparison, but only on the individual machines. I now own a Levinson No.39 player. Very nice, detailed and smooth. I am pleased with the player, but was hoping to kill 2 birds with one stone, i.e. the DV50s allegedly has incredible CD playback plus the DVD video feature. Not sure where the DVD-A and SACD formats are going, and don't really care. I stopped buying multi-channel audio disks last year.
