If you have Tidal, there are some MQA albums that sound incredibly good.i got my fiio m15 in combination with the meze empyrean (silver cable, balanced 4.4mm). in order to experience the "maximum" in high fidelity, do you have any song recommendations that gives a particular impression of its performance?
For example Eleanor McEvoy the song "Where's the healing?" from her album "What's following me?".
Or the new album from Céu "Um Gosto de Sol".
