No problem.. If you go to the Pro-Ject CD Box RS2T website description page they lay out their product design and objectives.
I had the Esoteric P700 which may have been the first generation of the VRDS disc clamp-drive unit. I purchased it in the mid-late 1990s. It still functions fine today! I have used it in various 2nd systems. When acquired it was considered one of the better CD transports for reasonable cost. I have heard numerous later generation Esoteric transports but have not owned them.
