In Reply to: isn't the issue with optical posted by Bruce from DC on February 27, 2019 at 10:06:27:
Just trying to get my brain around this stuff, not trying to start "trouble." ;-)
There really are different use cases going on. The venerable TOSLINK optical interface is typically used when the transport is nearby and doesn't necessarily involve a computer. It's challenge is the inherently high jitter associated with the standard.
In this case, however, optical is used as the "highway" for ethernet traffic between a music server and a digital endpoints located at considerable distances. In my case, the music server lives downstairs in the home office and connects to a gigabit router. From there it feeds a 60' run of CAT6 to the listening room upstairs. It connects to a Sonore ultraRendu endpoint which uses a USB interface to the Audio Research DAC.
Why that approach? I don't want an electrically noisy general purpose computer in my listening room. Control for the endpoint is via a phone/pad or even my watch. Centrally locating the digital library also means that I can access it from multiple players (audio and video alike) located around the house and garage.
Is that clear as mud? :)
