I understand your perspective with regard to potential software issues. I owned the P.S.Audio PWT for 12 very enjoyable years and initially did give some consideration to the current CD/SACD transport.
I just haven’t found SACD particularly compelling compared to high quality well recorded 16/44 Redbook CD via a good CD transport,. If others have had a different experience, that’s good and go for the SACD. I was told by two Audiogon members I trust that the Pro-Ject RS2T was better sounding.
I have not heard the new CD/SACD transport so certainly I’m in no position to verify. At this point it doesn’t matter, as the RS2T is a marvelous CD transport. As I’ve said previously I seriously doubt that you could go astray with any of the three choices.
