Tach RCS 2.0 and SACD?

Does anybody that has an Tach RCS 2.0 run SACD through the ADC/DAC? Does it degrade the SACD, or does the correction make up for it? Thanks.
Have owned and used both in the same system.
The TacT unit outperforms the SACD unit (Sony SADC1).
Note: The Sony SACD1 is no light weight, so this is saying something.
Getting the correction on top of it is the icing on the cake, very nice icing...

Note: As of 02-14-02 We are not a TacT dealer.
