Qobuz/Tidal Differences

how do you propose that the digital file is modified to provide that change in sound?  --Jerry

First, depends on what version of the master is being offered. The two services may not be using the same master or remaster as the source.

Second, by what method or tech are the albums being digitized. Qobuz clearly states everything on their site is a bit accurate transfer from the source. I don't know about Tidal.

Both playback without any harshness or glare, but I've found Qobuz to sound better in a head to head comparison of tracks. 

there have been past threads on this subject, op - pls search and you will easily find

short answer, both sound very very good, with a streaming set up well implemented... qobuz sounds slightly more ’solid’, less ’airy’ than tidal, which often has slightly more high frequency energy

Here's three: 

Lisa Batiashvili / Daniel Barenboim / Staatskapelle Berlin
Tchaikovsky, Sibelius: Violin Concertos

'The Box' by Roddy Ricch - Not what I usually listen to, but I thought I might include something possibly more favorable to Tidal's tonal qualities. Still sounded a lot worse on Tidal than on Qobuz

Jennifer Warnes - Famous Blue Raincoat

jjss49, I've seen lots  of threads where people express their likes/dislikes for one services or the other and their reasons for it, but not any that come to mind where actual recordings are named so others who want to can also compare to see if they hear things the same way.

c&h, thanks for the track list.  I'll give them a listen to see if I can hear a difference.
