Noticably better at doing what?
The DAC chips in your old player are not only cheap, they are obsolete. The error rate on those things is crappy by current standards.
Error rate? Are you kidding me? Even cheap obsolete DACs have for all intents and purposes zero error rates.
Anyone who is silly enough to think that DAC conversion accuracy has not improved in the last 15 years is woefully unaware of the advances in DAC engineering that have taken place.
Almost all of the significant sound quality improvements that have happened in DACs in the last 10-15 years have been improvements in price performance.
10 years ago we had DACs with 120 dB dynamic range, and high sample rates. They just cost thousands of dollars.
In terms of audible benefits in the home, there hasn't been a significant change since the middle 1980s, because that is when mainstream CD players starting having performance that was so good that built-in noise and distortion due to the acoustic and analog components in the recording process was so much higher.
If you listen through a cheap HT receiver that has poor-quality amplifiers, you may not be able to tell the difference in sound quality between CD players,
If you use the best amps and speakers around, you will have the same problem. Been there done that, and this has been true since the middle 1980s.

but if you have a decent amplifier and speakers, the differences are certainly there to be heard.
It appears that you have avoided contact with well-done listening tests.
