Since you already have a Synology NAS drive, I would suggest you purchase a Sonore Microrendu , and let it do all the music workflow between your NAS drive, DAC and computer. With it in place, your music files will no longer run through your computer, which can degrade the sound quality. You computer simply uses a program like Roon, JRiver, etc. to direct the Microrendu and tell it what to do with the music files on your NAS. Your sound quality will improve quite a bit, and you can use any computer, laptop or tablet you wish. The computer will no longer be a limiting factor to your sound quality.
