Need advice on digital inputs


Looking for a little advice on something...still a bit new to all of this. I have an NAD c379 preamp and a Cambridge audio cxn100 streamer. I have the Cambridge hooked up to the NAD from the analog outs on the Cambridge to the analog ins of the NAD. Both of these units have good dacs, so having it hooked up like this which dac am I using, the Cambridge or the NAD?? The Cambridge has digital inputs and outputs, the NAD only has digital inputs, how do I use these on the Cambridge unit? Thank you for all and any advice.

If i use the digital out on the Cambridge ( coax) what exactly am I connecting it to on the NAD? The NAD doesn't have any digital inputs.

The NAD C379 has two optical in and two coax in. Not sure what you are not seeing. Read the manual.

It was stupid of NAD to label the RCA/SPDIF digital inputs as coaxial in as that’s a general term that could mean anything, and for exactly this reason pretty much the whole world calls it a digital input but yes that’s the input you’d use.

Correct me if I'm erring.

RCA is analog, with R and L connections. Coax is digital, using only one connection. The NAD has two coax for two different connections, not to be used together like RCA.
