What do modern, current day CD Transports do that older CDP's with RCA digital out don't?


I have read a few posts saying that even a modern inexpensive CD transport can sound better with modern DACs than older, more expensive CD players equipped with digital outputs (RCA digital output).

I understand very old CD players with optical outputs only can be poorer sounding due to the optical interface. But I would be curious to learn about how a nice $2000 Sony ES or Marantz higher grade CD player from 12-15 years ago, with RCA digital out won’t work just as well feeding a DAC as say, an modern Audiolab slot loading transport for about $600.  Let's consider the older player is working without problems, like bad laser or mechanical problems.

Hopeful that someone here can explain what the new stuff has on board that works in their favor.

I hope this doesn't hi jack this thread. I hope this is in the spirit of the thread. If not I apologize. I have an old Theta Pearl CDT, Late 1980's I believe. I have had it about 10 years and works great. And sounds noticeably better than my Marantz CD recorder, Pioneer Blue Ray player as a transport, my NAD 5000 cd player as a transport. Has anyone here had one, if so what did you go to and what significant difference do you notice. Thank you
