Which site is Best for Downloading/Uploading Hi Rez

Hi,

   I quite new to this game of streaming,uploading and High resolution music.Ive been for a good part of my life into Vinyl/CD.I would say for the last 1 or so ive been dabbling into the world of internet coupled with audio.I bought about 6 months ago a Cambridge CNX Internet Music Player(Streamer),and I must say,its quite impressive! I was excpecting it to sound artificial and "Clinical" sounding,but to my surprise it was natural in sound.Ive also gotton into DAPs or digital audio players! Im only using Spotify,and im not too sure what sampling rate this would be considered? Does there exist particular sites that I could get "High Rez" music,and that it wouldnt cost me much more than Spotify or even Tidal?
