I'm currently using an Allo Boss V1.2 with a Raspberry Pi but am considering an NJC Audio DAC to compliment my NJC headphone amp.

I'm considering using an optical connection and wonder which is currently the best Digi hat to use, can anyone advise please.

Also, is there likely to be any SQ difference between a Pi with a Digi hat and a Chromecast Audio?

Cheers,

Bill
