I moved from Spotify to Qobuz about a year ago and now listen almost exclusively to Qobuz through Sonos into my HiFi. The sound quality is hard to distinguish from CDs and I've been really pleased with Qobuz.
I've taken up the one month free trial with Tidal as an 'early adopter'. I was a little disappointed that Tidal isn't yet integrated into Sonos as What HiFi magazine had reported that it would be integrated from launch. However, I understand that this will be coming soon. My first impressions of Tidal are very good. The Android app is a definite step up from the lousy Qobuz app and the the desktop application and web player are both very good - clean and intuitive. Sound quality seems to be on a par with Qobuz but I'll reserve final judgement until I've had a chance to do more listening through my HiFi when Tidal gets integrated into Sonos.
Track availability seems to be a little better than Qobuz, though the big omissions are still there - AC/DC, Led Zep, Beatles, etc. According to the quoted figures, Tidal should have around ten million more tracks than Qobuz but I wonder if the gap is really that big? Does anyone independent actually check the claimed track numbers? Also, I recall Spotify having numerous 'best of' compilations for older artists - a definite case of more is less. And I wonder if each time 'What a Wonderful World', or whatever, appears is counted multiple times? Just how reliable or meaningful are the quoted track numbers for the various streaming apps?
The videos are a nice bonus on Tidal - they don't player on the desktop app though - only the web player and mobile apps. It would be nice to see this integrated into my TV (Virgin Media).
I'm advised by Tidal that when Android Lollipop is released in a week or so, supporting USB Audio, it will be possible to use an external USB DAC/amp with Tidal. I have an HRT Microstreamer so I'm looking forward to trying this.
I've been using Qobuz in my bedroom through an old Iphone 3GS but Tidal will not work with this as it requires a more recent version of IOS than the 3GS will update to, which is disappointing.
Overall, once Tidal have the Sonos integration sorted I think I'll be switching to them from Qobuz.
