Tidal vs. Spotify

Tried both and it was no contest. Inputting the native Spotify signal to the dac followed by upsampling wins hands down.
Guess Windows was doing a hack job of digital upscaling. :)

Glad you got an improvement, Jon.  Check out The Antisocial Club when you get a chance.  Maybe you will like it.

Ghosthouse, thanks for the heads up. Will check it out.
The Jazz for Autumn playlist is what I have been listening to for my recent experiment.
It's interesting that Spotify does indeed sound like redbook quality.

I use  Tidal with Roon software installed on MacMini which is connected via USB to  Marantz NA11S DAC/network player.
The integration is flawless and sound quality is really like CD one.

So after having spotify premium for quite a while now I can say I'm totally satisfied. Search "audiophile" playlists. The first few will blow you away. Just go through all the songs on the list. Most those recordings are nothing short of incredible. You'll be staying up for hours and hours late into the night, not being able to stop listening.
