Hi Alpha,
From what I have learned, the video ability of the SV-50 affects the quality of the audio. The transports VSOP or VRDS-neo also play an important role with the later being superior.The new SA-50 has the cheaper transport but has perhaps a better dac?,and imputs.I've been listening to as many Esoterics as possible and starting to hear the differences between what I been able to hear.Most, but not all has been on the same system,one I'm familiar with.
