Basically you have your music on the cloud or on your PC/NAS. If it's on the cloud , you will use your smartphone to access your account and play. From your smartphone, in order to send the music to your DAC (DACs have USB and/or S/PDIF inputs) you need a transport that will be visible (to your smartphone / tablet /PC) as an Airplay device (iOS ) or UPNP/DLNA (Android/PC).
Our transports have different outputs. USBridge is feeding your DAC through USB and DigiOne is using coaxial/bnc. Depending on your DAC inputs you need to make a choice.
We started designing a digital (S/PDIF) transport for RPI with one goal in mind: Absolut best S/PDIF output.
Now let me explain... behind the grandiose wording there is an exact science. Since this is a digital stream the most important aspect for "absolut best" is jitter. Jitter in digital domain directly translates into analog errors. Second, is noise. Lowering the noise that's injected in your DAC will produce some (small-to-none) improvements.
The Digione has a galvanic isolator for both power and signals. You do not need an extra isolator. As well, DigiOne has a double relocking of the S/PDIF stream (one of them taking care of metastability and the second one taking care of realigning the data). You do not need another reclocker (like Kali).
Compatibility: RPI only
PSU: Not needed (power is taken from RPI, then we use a isolated DC/DC convertor with filters and LDO)
Not Working With: Sparky, Isolator, Kali
