I have a new Cambridge Audio CXA80 amp, with all the possible options for digital connection, and I want to use a Raspberry pi 4 as my streamer player, from my FLAC collection in my home server.
What is, in your opinion, the best option?
Should I connect the Raspberry directly by USB to the amp?
Or, should I add an HAT, and connect through Toslink optical or coaxial?
I will receive my Raspberry pi 4 tomorrow, so I will use USB right from the start, so my question is: Should I think about adding an HAT?
