@vonhelmholtz Why not invest in a proper high resolution file server instead? Do you already have the CDs that you want to be playing through a transport? If not, you will still have to find and buy them. Most high resolution albums, even DSD versions from a SACD are available for purchase for download to local storage from HDTracks, 7digital, or other services. A proper high resolution server will have no spinning parts, hence less vibration, with lower noise through a quality internal LPS, SSD storage and file caching, and improved isolation from non-digital signals. You will get a bit further with your money this route, as chances are you would invest in a file server down the road anyways once buying, storing, and playing discs becomes too cumbersome.
The NUC you have is a great start but there are much better server solutions that include the features I list above, and the sound quality will be a huge step forward with them as a result. Happy to chat options with you over PM.
