I spent an afternoon at my friendly dealer (Martins in Norwich) switching in Tidal between all available sources, using DCS and Vitus kit. We came to a view that maybe 1/3rd were better to us with MQA, vs other formats. In my view therefore not amazingly reliable as "it all depends on the track" which is not amazingly helpful in playing a range of tracks at home at leisure. Also what is true MQA? - the source is not usually identified - we need transparency before I personally would be that bothered.
