I want to use spfdif. I'll be using a Roku Soundbridge that has both optical and coaxial out.

I have a digital coaxial cable that has rca connectors on both ends.

Do I need an adapter or cable of some kind?

If I need an adapter, where can I buy it. A link would be great.

If I need a cable, what kind of cable do I need and what kind of termination on both ends of the cable?

Where can I buy the cable that I need? A link to buy the cable would be great.

Bluetooth, USB, and Line-in works great, especially for $20 clearance.

Thanks in advance.

Roku Soundbridge has a coaxial SPDIF output, you have a coaxial SPDIF cable, and the Big Blue Amp has a coaxial SPDIF input. Seems to me like you already have everything you need. Were you not able to get that working?

Roku Soundbridge has a coaxial SPDIF output, you have a coaxial SPDIF cable, and the Big Blue Amp has a coaxial SPDIF input.

That is correct. But, the Big Blue Amp has 3.5mm SPDIF input jack. Therefore, that's why I asked, what kind of cable and/or adapter do I need to connect my Roku Soundbridge coaxial SPDIF RCA output to 3.5mm Big Blue Amp coaxial SPDIF input?

I'm thinking I need a female rca to 3.5mm mono adapter? Is that correct?

Or a Fiio L21 digital coaxial cable terminated with RCA to 3.5mm TRRS plug? Is that correct?

Is this your amp?

The PDF manual shows a SPDIF in port which I assume is RCA. I couldn't find any actual photos of it. Is it RCA or something else?

Yes, that's the amp. Again, the amp SPDIF input is 3.5mm not RCA.

Therefore, my questions remain.
