You can stream tidal right from your mobile phone if you want to, I do in the car!
What HiFi is definitely wrong on that one!
Tidal can be streamed by desktop pc ( worst interface imho!), laptop, tablet, ipad, iPhone, droid phone etc etc etc.
Basically anything you can download a Tidal app to you can stream from it.
Trust me I have been doing exactly this for nigh on 2 years!
I do have a Bluesound Vault 2 that I use at home and in all honesty the Tidal interface WITHIN the Bluos app is by far superior to any other I have tried,
