Tidal HiFi really lossless?

Once you select “high quality” for your streaming quality, you’ll get lossless playback. It streams to you in a compressed format so you’ll never see 1,411 kbps over the internet but your device is converting it to 16-bit/44.1kHz/1,411 kbps and sends that to the DAC chip.

Tidal is lossless but I've never gotten up to 1411 kbps streaming Redbook. It typically sits in the 7-1000 kbps range even on Wifi in my home. Sounds great though.

You have to set it correctly. On the phone, there's a streamer quality setting, same for the PC app.  Not sure about OS X.
