Sound quality is not the same as music quality.
To be more specific, Sound Reproduction Fidelity is not the same as Pleasant Music
To be even more specific, Signal Reproduction is not the same as "Pleasant Sounds*

The only thing objective in this context is signal reproduction, which is not the highest concern for music production.
