Well DSD via SE not that bad considering not Native. Chord Mojo & Hugo2 much better, but hopefully will do once the Sony balanced 4.4mm cable arrives for my SE846's.
Everything else sounds fabulous, even in DAC mode with Tidal HiFi especially good via UAPP app.
Tidal on PC with ZX300 doesn't seem to pass MQA and I also downloaded a demo MQA file to the ZX300 itself and doesn't seem to see the track. Is MQA enabled yet?
My setup now with Z5 compact linked together. Really neat and not to heavy.
I have the same query on MQA.
