Hi, hoping you could advise I'm often in my study/computer room and have many mp3s on my computer (quite a few that I don't have on CD) - I find myself listening to more music here than in the lounge so I was after ways I could improve the sound (if its possible). The mp3s are only 128kbps played through iTunes then out of a Audigy 2 ZS sound card to some Logitech Z5500 computer speakers. I have a TAG Mclaren DAC 20 not currently being used for anything so though perhaps using this from the PC via optical then buying a cheap second hand amp and second hand stereo speakers - now I'm talking real budget stuff here - about £300 for both the SH amp & speakers. Would this improve my sound much? Or would it still be sub-par? Any other suggestions? Thanks.
