SCD-1 & SCD-777ES Sonically What's the Difference?


I own the Sony SCD-777ES. I have been told that the transports to both this and the SCD-1 are exactly alike. Therefore, am I missing something sonically by not owning the SCD-1, or is the $600-$800 price difference for the SCD-1 just simply so one can own the original "flagship" of the SACD line? Cosmetically they seem very different but that isn't of major concern to me.

I believe the SCD-1 has 2 power supplies plus balanced outputs. Sonically there probably isn't a difference.

And it doesn't have two power supplies either.

The transformer is potted in the SCD-1, however.
