"Recent study is starting to show that this is not the case, the phase noise from other clocks can overlay the noise from the local clock. Thus phase noise form other clocks can contaminate the local clock. Even if this "bleed through" is small, the phase noise from devices such as consumer switches and routers is many orders of magnitude higher than that of really low phase noise oscillators used in better DACs. The result is that you are not getting what you paid for in that DAC. In order for the DAC to sound as good as it should, this clock contamination needs to be dealt with. "
Entre le méchant switch et la puce du DAC, il y a :

Entre le méchant switch et la puce du DAC, il y a :
- une liaison Ethernet dépourvu de ligne d'horloge
- une isolation galvanique (si on a un isolateur standard)
- du soft
- une sortie audio
- Un convertisseur USB asynchrone avec FIFO + PLL ou un reclocker I2S.
