Allora ho scritto al Magna hi-fi esprimendo una richiesta riguardo le differenze sonore tra il Sabre e il Dac19. Ho spiegato loro il mio progetto e il modo in cui vorrei far arrivare il segnale i2S al dac (ovvero attraverso la schedina HDmi audio GD). La loro risposta è stata la seguente:
"The sound of the NFB 1 is not cold but I admit and agree the DAC 19 is simply more natural and fluent.
When you want to connect the Raspberry Pi you will need a Master Clock signal for DAC 19 in order to function properly.
The NFB 1 does not need this Master Clock signal becuase it is asynchronous DAC. Much more easier to use.
BUT.....................
If you really want good music form your Pi you should buy the Hifiberry DAC Pro+ board and connect it with I2S out to the DAC 19.
It will have super clocks and very good power supplies onboard separated from Raspberry Pi.
The DAC Pro+ board is ~ 45 Euro and is very good value/price.
If you want I can offer you a Hifiberry Pro+ board with Audio-GD HDMI Output module connected and tested for 75 Euro. (Hifiberry Pro+ 45 euro and HDMI Output 20 Euro)
It is a very good solution!

This solution generates a master clock and could directly be attached to your DAC 19 and fully support Volumio
Really nice

We have tested this solution and is working very well."
Qualcuno sa spiegarmi cosa vuol dire?
