[jasonC]

Will provide a bnc adapter and a bnc to twin rca cable.
£60 plus a fiver delivery.

Will supply a bnc adapter that allows you to use a standard interconnect cable on the bnc input on the digione.

You can though use a coxial cable.

Also provided will be a one meter bnc to twin phone interconnect.


First... What is a Transport Basically you have your music on the cloud or on your PC/NAS.

If its 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.

USBridgeis feeding your DAC through USB and DigiOneis 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 thats injected in your DAC will produce some (small-to-none) improvements.

Then we went to work. 10 LDOs, 12 LPF, DC/DC convertors, galvanic isolator, WM8805, flip flops, buffers. Optical had to go by definition it has a jitter of 4ns. Thats 4000ps.

We simply removed it.

However, optical has galvanic isolation so we took the decision to use a digital isolator instead that separates the outputs from both RPI and WM8805.

DigiOne has 2 outputs: BNC and plain RCA (coaxial). On both, we have achieved jitter of 0.6ps (1 picosecond time taken by light in a vacuum to travel approximately 0.30 mm).

Noise. 50uV (batteries have about 12uV of noise).
What we achieved, in our opinion and based on public measurements, is the best transport at any price point (yes, even when compared with 5k USD/EUR transports).

Compatibility 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 Features 10 LDOs, 12 LPF, DC/DC convertors, galvanic isolator, WM8805, flip flops, buffers. 2 outputs: BNC and plain RCA (coaxial) Noise. 50uV
