Reading this thread I feel uneducated.
I have physical media, and I rip it to FLAC.
This has always been my definition of "lossless"
So when we say that qobuz "sounds better" than tidal, are they not both just lossless streams of the album?
If they are both lossless of studio albums how should it be possible that one "sounds better" than the other?
No, you're not the uneducated one.
It's possible that one service uses a different master than another, which would produce (probably significant) differences in sound from "the same" album. Otherwise why did they bother remastering?
However, one lossless file sounds
exactly the same as another lossless version of the same recording. That's actually the whole point.
People who assert that one lossless stream is audibly different than another stream of the same master either:
A) Have something wrong with their audio drivers / DAC
B) Have good imaginations fueled by very hazy ideas of what digital audio is.
C) Think they can hear sounds above 22khz and highly value 96Khz encoding because their great-grandmother on their mother's side was a bat.
If it's B, they might think the audio signal is being sent in a direct stream, individual bit by bit, from the Tidal or qobuz data center, in a way that's analogous to a voltage traveling up and down a wire in their system. In which case, audible differences in lossless streaming implementation might... happen somehow. This is NOT REMOTELY close to how digital audio (or any other data) is sent over the internet. There's really no chance for differences to creep in except via gain or different masters.
