I sold my reference quality cd player 15 years ago because ripped music sounded better using 3rd party software like Pure Music. I still have a Sony $1500 SACD/cd player that I have used maybe 5 times in the last 10 years. With high res files and mqa, I sold my $15k turntable and all my vinyl and have never regretted it.
Looking at some of these posts, they are using cheap stuff like blue jean cables or $100 audioquest cables, like those are high quality. My old usb cable when I used to own that flawed interface was close to $1000.
The reader software you use makes all the difference for playback quality. If you use Apple’s iTunes/music software, anything will sound better. But if you use Audirvana or Roon, your playback quality goes way up.
Also, when you use a cd player, are you using toslink or coax outputs into an external dac? If so, those are the worst out[uts to use but not as bad as usb, so you already compromised your sound. Or if you use the single ended or balanced outputs, then you are really compromising the sound quality because you are using the internal dac inside the cd player. I have never heard a cd players internal dac sound any good (same goes for dacs built into integrated amps) compared to a standalone quality dac, like the Briscati, DCS, or PS Audio standalone dacs.
