I would like to share an audio tweak I came across recently:
MBP mid 2010, 4 GB RAM, High-Sierra, max. memory allocated for tracks pre-load 1 GB
Audirvana, latest version, Qobuz Hi-Fi, no local stored files
MBP receives Qobuz via Wi-Fi only, output via USB to DAC
Directly after loading the files into RAM I turn Wi-Fi off at the menu bar.
From a pure SQ POV the improvement is subtle but the music is more involving, the interplay of the musicians seems to be better, the music makes more sense and some hardness disappears, the presentation is smoother.
Try and enjoy
