Yamaha CD S1000 or S2100 as transport

This is for owners of the Yamaha CD S1000, S21000 or S3000 CD players. I want to use one of these as a transport-only paired with an external DAC. Since they all seem to use the same rigid aluminum transport mechanism and laser, would there be a noticeable difference in sound quality between them? I'd like to go with the S1000 since it's significantly less expensive, but I'm willing to spend more if the SQ of the S2100 or S3000 is better.

Thoughts appreciated*

* Not interested in suggestions to use a different transport than one of these three, so please stay on topic.
