Nothing. I just thought I had read somewhere, that the Accuphase transports since DP-800 were made by Accuphase themselves (except for the laser diode)
and Sony had ceased the production of SACD / CD transports.

Accuphase DACs use an analog filter with 50kHz bandwidth at the outputs. Such a filter would make no sense, if CDs were converted at native 44.1kHz.
In order for this filter to make sense with CDs, the sampling frequency before conversion must be greater than 2x50kHz.
This means, an upsampling of the native 44.1kHz CD to at least 176.4kHz before conversion into analog is required.
So 'no upsampling / oversampling' according to the test report cannot be correct.
