To get the best possible sound from your audio system you need to start with the best possible version of the song/album. From a music streaming position, we’ll leave CD and LP for another discussion, the best quality available is from TIDAL. Unlike other streaming services, TIDAL allows a listener to stream at 3 different tiers, from medium quality MP3 to CD resolution and with the correct hardware at high-resolution MQA.
The first month at TIDAL is free. Try it. Make sure you select “Hi-Fi subscription” and compare.
