I've got a Myryad MI120 playing through original Epos ES14 speakers. Currently it's fed by a £50 DAC connected over Bluetooth and Chord C-line RCA cables. So, basically a respectable mid-range combination fed by a relatively inexpensive DAC. I'm just wondering if anybody here has made a similar upgrade and what a difference it made? My music collection is nearly all FLAC ripped from CD.
