I think that from your narrowed down list of the 3 CD transports you’d have been very satisfied. No dog in this trio. Pro-Ject’s design mission for their “Box” components is small/compact and space saving. Made from aluminum and carbon fiber it’s diminutive yet a dense feel to it.
I don’t believe it is by accident that several very upscale/expensive CD transport manufacturers have chosen to utilize the Stream Unlimited Pro-8 unit/Blue Tiger servo pairing.
The RS2T is probably 1/5 the weight of my former P.S. Audio PWT but simply out performs it across the board. So although light in weight they have obviously been successful in addressing vibration issues that can affect spinning CD drive units. I’ve enjoyed my RS2T immensely as the sound quality is superb.
Best wishes,
