Directly to the amp will work just fine. Should your DAC have a analog input, many don't, try it and see which you like best.
Connect bluetooth receiver directly to tube amp
I'm thinking of getting a Yaqin mc-10L tube amp and connecting a bluetooth audio receiver (HomeSpot NFC)to stream online music eg. spotify from my android phone via bluetooth. The amp will be driving a pair of Totem Rainmakers. Question is whether I should to connect the bluetooth receiver to a DAC first or will connecting directly to the amp work fine?
