Jays Audio cdt2 mk3 burn in and user experiences

I got one to replace my Audiolab 6000cdt that was scratching discs. The Jays was disappointing sounding out of the box, wondering if I had made a good choice, the Audiolab sounded better at that point but after 24 hours the Jays is sounding much better. Jays Audio recommends burning it in for 400 hours, what is your experience with burn in? Just using the rca dig out right now. Wondering about the upgraded cd clamp. Anything else to know?
