Soundquality spotify VS Qobuz, tidal, deezer?

[jonstatt]

Any "lossless" CD streaming service will sound the same. Both advertise they do absolutely no processing to the lossless stream. So Qobuz and Tidal at their higher level price options will sound no different to each other. Spotify doesn't do lossless yet and  I don't believe Deezer does either...so they will be inferior.

Should be but isn't. When listening to the same tracks streamed lossless Qobuz has a significantly better resolution. In fact I can't listen to sonically difficult material over Tidal. It simply isn't fun.

Interesting. I did compare myself using IEMs on my Sony NW-ZX2 DAP and couldn't hear a difference in quality although for some reason there was a slight difference in volume. However sometimes Tidal delivers a compressed version of the track instead of the lossless version and unless you check for it, you don't notice. I wonder if this is what was happening to you.
