Wow - that
s quite a strong statement in terms of SQ. Are you sure you got all the settings right when comparing the two? I only had the hifi free-trial with Qobuz and so I only compared some 44.1 FLAC files - really cant remember the differences to be this drastic… also - when I imported my files from Tidal to Qobuz with Soundiiz alone in the Indi/Alternative genre it was missing 200 songs - the catalogue Tidal has with Rock/Pop/Indi/Alternative/Punk seems to be much bigger…
… here`s a review I found on the internet - which actually goes confirm with my own findings:
Using both services via their webplayer platforms there are some surprising differences in what you hear, Qobuz is distinctly louder than Tidal, which suggests some kind of compression is being used, its streams also suffered from drop out whereas the Tidal site can be slow to load new pages but delivers a smooth stream. Sound quality wise Tidal is the more neutral of the two on the webplayer while Qobuz has a juicier sound with fuller bass, at least this was the case with Esperanza Spalding’s ‘Judas’. Comparing the two with an Innuos Zenith SE server as source and CAD 1543 MkII DAC there was very little difference at all, both sound pretty good if not in the same league as material stored on the server itself.
The bit/sample rate of lossless streaming offered by both is CD standard 16-bit/44.1kHz but both have high res options, Tidal uses MQA to encode its Masters series releases which are generally 24-bit and either 44.1 or 48kHz but go up to 192 with some material. On the PC you need Tidal’s desktop app in order to play Masters resolution files, all hardware based systems include it as part of the package.
Qobuz’s premium service Sublime+ offers material at up to 24/96 without MQA decoding, again you need to use the desktop app on a PC, or audio hardware to access it. The other bonus for those looking for maximum sound quality is that Qobuz sells downloads of high res material and discounts its prices for Sublime+ customers, Tidal is purely a streaming platform.”
