Hope I'm in the right forum for starters. I'm looking to downsize my hi-fi set-up and have the vast majority of my source being my PC (FLAC/MP3 files, Internet Radio and Spotify etc). In the past I have fed my amp from my PC via a Beresford DAC/Toslink cable. At the moment it is via a Naim Uniti. The Uniti is going, fantastic piece of kit but I need the finance elsewhere. I would like any opinions as to whether it is worth my while upgrading my onboard Realtek s/c to a better "audiophile" s/c (Asus Xonar Essence for example) and feed my amp directly from my PC, or to buy myself something like a Beresford Caiman DAC and continue using a Toslink cable etc. I've never had anything on my PC's before other than the standard onboard s/c so have no real experience of whether I could expect a big improvement by upgrading s/c's. Your thoughts would be most appreciated. Regards .
