I just got my rpi b+ and found that there’re few DAC for b+. But my question is: Do I really need a DAC?
which config is better?
1 rpi–I2S–>DAC–rca–>T amp --> speaker
2 rpi --I2S–>DAC–spdif–> AV receiver–> speaker
3 rpi --hdmi --> AV receiver --> speaker
I have a Marantz NR1604 av receiver which have hdmi inputs as well as spdif and toslink. I also have a Topping tp20 class T amp laying around.
As config 3, I’m using DAC in 1604 which support up to 24bits/192khz
