In a nutshell: when Pro-Ject first came out, it was declared sonically superior to Jay’s CDT2MK3 ( I don’t believe the Jay’s CDT3MK3 had come out, yet) by a good many here. Then, Pro-ject started having QC issues. One forum member reported going through several units before he was sent one that was glitch-free. That was quite a while ago. I have no idea of how things stand, now.
I have the Jay’s CDT2MK3 and love it. I tried the Pro-Ject and found it to be a PITA ergonomically, due to its light weight and tiny footprint. I had to simultaneously hold it steady with one hand while inserting/removing discs with the other hand. The Jay’s is much larger/heavier. No such problems with it. To be fair, I seem to be the only one here who’s complained of this, so all I can assume is, other guys have apparently figured out ways to adhere the unit to their shelves/racks.
My 2 cents...
Oh yeah: I was able to by a spare drive with my Jay’s. Not sure whether these are still available. Here's link to ask them:
