Classe Omega SACD-1 same as Sony SCD-1?

I realize that Classe has made their own proprietary mods to the Sony SCD-1's transport and software and Classe uses an outboard power supply. Is there or should one expect there to be a major sonic difference? What is the true difference besides price between these players?
Stereophile reviewed the Omega SACD-1 last year (can't recall the month). From my recall, Classe is just using the Sony transport. The electronics are all new.

The SACD-1 uses separate signal paths for redbook and SACD. I think it upsamples redbook to 96khz. It uses 3 DSD converters per channel for SACD.

For all that change it ought to sound different than the SCD-1.
