Matsaly - Just to follow on from Bruce's comments ... looking at your equipment list, you're not getting any unpacked MQA goodness when you play Tidal tracks through your main system.
Your MC200 is not decoding the MQA file at all - the firmware changes to enable this haven't arrived yet. Like Bruce says, it's simply passing the backwards-compatible MQA file through its DAC, which treats it just like a conventional FLAC audio file.
Apparently a non-decoded MQA file still sounds a bit better than conventional 44.1/16 audio, so any improvements you're hearing in your main system are due to this. So like Bruce says, to get the full MQA experience - pending the release of new MQA decoding firmware for your MC200 - you'll need an Ultra DAC, 808v6, 818v3, or 218 to do the decoding.
HTH! :-)
