I'm a relatively new subscriber to Tidal and am somewhat surprised about the vastly different sound quality between albums whether original or remastered. Some albums sound great even though playback says "normal" and others listed as " hi fi " sound poor by comparison. Other albums are obviously mono and one in particular ( Marion McPartland plays Bernstein ) sounds as if it was vinyl as clicks, plops and even stylus noise are very evident. Tidal and Spotify do not seem consistent but maybe Qobuz, when available in Australia could be the answer to better overall sound.
