@stuartk , a nice system. I agree that since you’re using the Synchromesh and Steve’s cable there shouldn't be any jitter issues. I mentioned it earlier, vibration control is important to the dac and the transport, either with footers or cones in combination with a platform. Some components respond well to mass loading.
Power cords for digital devices have a tremendous influence on sonics. You should be auditioning different PC’s since they will impart their own sonic signature to the component. Shielded cables are preferred according to many designers.
My big question to you is, are you using a linear PS on the Synchromesh or the stock wall-wart?
And as stated by others, separate power to analogue and digital is recommended. It will help reduce the noise generated by digital devices that can contaminate the mains. I’m not sure if you’ve installed dedicated lines, but the digital sources should be on an isolated power strip or conditioner with filtering.
In my digital setup every time I swapped a PC or SPDIF cable there was a change to the SQ and timbre of the music.
