The solution to all of these problems is to use Ethernet to distribute audio to the location of the audio system. Then one can have the server and music storage located far away (in another room, basement, closet, etc) where its noise (electrical, EMI, radiated, etc) will not impact the audio system itself. The server, in another room, can be running even the most sophisticated software (like HQPlayer and ROON together, oversampling to DSD 512, for example) and if it is 30 feet away and powered from a different circuit, the noise made by the server will not matter to the audio system. Ethernet is isolated by transformers (for more robust isolation one can use optical fiber Ethernet) and transmits little noise to the endpoint (Renderer). With this approach one can run even the most sophisticated playback software, without a concern for the noise it produces. Just choose a very good, low power, ultra low noise, purpose built for audio Renderer and one can avoid these problems.
