You don’t mention a budget, and the previous responses assume you want the cheapest solutions. However, I note you asked what the best way is, not the most cost-effective. The best way, in terms of sound quality at least, to take most advantage of Hi-Res streams on Tidal, would be with an 800 series product with an ID40 or ID41 card. In a 2-channel system, the best would be an 818v3, or 808.6. You would then need Roon (running on a suitable NUC or PC/Mac, etc.). Tidal is very well integrated into Roon.

[edit: sorry, posted from my phone last night and your signature wasn’t visible. As you have a multichannel system, you could consider a 861 with ID40/41 card to replace your Anthem. Many of us feel that the 861 is still the best sounding processor. Particularly with DSPs you might find it exceptional).
