I think your best bet is to get a dedicated transport and place it next to the DAC, for example, allo usbbridge or a hifiberry device. Of course, this depends on your source, if you only play local files from you NAS it's a good approach. If you want to use a streaming service Roon is an easy option to run on the transport.
If you PC runs Linux you can use setup pulse locally to use a remote transport as sound device and all your PC sound would end up there.
If you run Windows I have no experience, but I believe JACK is able to with ASIO bridge on a win box.
In short, I think buying a raspi is the cheapest and best way of not using a long cable. :-)
