A computer directly to a DAC is almost always a no go. Though I would not be surprised if the latest PlayBack Designs DACs are not affected.
Reason you do not want to hookup a general purpose computer directly to the DAC is that the electrical noise in the computer would travel into the DAC. You want to have a moat around the computer or use a dedicated music server, which is just an audio optimized computer.
I use a general-purpose computer ($500) to run my ROON Core. I also use a Sonore OpticalRendu to provide the moat. The oR uses fibre optic cable which is made of glass and glass cannot carry the noise from the computer, network, printers, security systems, that may be connected to your home computer network.
The OpticalRendu’s can be found for under $1000. Last used one I bought cost me $700. The other parts needed could add about $300-$500 more. This is very high-quality stream.
BTW - If you use ROON with my suggestion you would have a great and easy to use streaming setup.
