Tidal is not HiRez but just CD quality (i.e. 16/44), but that may be all you will ever need in any case. Your Hegel has a usb input, so all you will need is a simple standard usb cable from the usb ouput of the laptop to the usb input of the Hegel.
If you do not want to tie up your laptop for this purpose, you can also use a simple streamer like the Apple Airport Express or the Chromecast Audio (I prefer the latter because it does not tie up your phone/tablet). Both have digital optical outputs (get the right mini optical cable) so they can easily be connected to the digital optical input of the Hegel.
