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.

Digital Out can be different that the player's RCA outs

i.e. some do not always send SACD's DSD out the digital, but convert DSD to PCM internally

also, if sending to external dac, what internal OEM processing may have already occurred in older players prior to digital out?  I have no idea, just wondering if ....

I have an older Sony ES and a Yamaha that have far better built drive assemblies.

and if you go even further back, you have the “mechanism that doesn‘t wear out“, the grandaddy of them all, an engineering masterpiece that still eclipses anything ever built for durability. Is everything built henceforth a marketing ploy?……maybe…….

looks like you aren’t going to get the answers you are looking for here

maybe check out some detailed reviews on the audiolab and other modern dedicated transports... they may have in depth technical explanations and in use comparisons that can shed light on your query

all you are getting here is heat, not light

this last one ^^^ is very interesting... miguel is very smart, maybe too much info for you, going past what you are asking, but this guy is impressive, and this vid provides real insight into what is going on inside the unit

most of all, use your own ears and decide for yourself. You can read all the reviews and theory in the universe, but in the end it‘s the sound that counts..

No but with a new quality transport and a quality DAC I can get close and I can buy new CD's on Amazon for under $10.00 and it sounds better than streaming. I am in. I will never give up vinyl and still stream to here new artists. But if I can pick up a CD for less by an artist I really like....

There's a fad to use CD's again. Unlike vinyl its not valid for better SQ.
