Because it will have heavy use in my office I asked him about the opening/closing/disc changing smoothness of his unit.
He said these had a reputation from day one to be a bit noisy and his was no exception.
Beside the plastic tray noise, I think it's very smooth and quiet for a changer. Certainly much better than my Sony SACD changer which always sounds like its on its death march.
