I stream both Tidal and Qobuzz via a Cambridge CXNv2 to a Benchmark DAC 3b, I would say Tidal is slightly better than straight Redbook although I am using a Sony XA5400 ES which Stereophile gave an A+ to. I think that may be because they are using newer masters with better methods than the older CDs I have. I would also say Qobuzz in general sounds better than Tidal in general and Qobuzz high rez is better yet although some sound a bit edged... like an over-sharpened photo. I find Tidal easier to use and seems to have more material when I look for a particular artist. For the price of 2 CDs a month I'll keep them both. FWIW, there are some internet radio stations out there broadcasting in 250 and 320 kbps that sound as good as Qobuzz hi rez.
