Am thinking of getting a DAC that takes a USB input and hooking my speakers up to that. Has anybody had any experience doing this via the 24" LED USB ports? Can't think of a reason why it wouldn't work but... I'm not keen on having to plug in one extra cable to my macbook pro everytime I 'dock' it. If this isn't a goer - is there any other solutions (know about the 3rd party dock in development for the new uni and the few bluetooth speakers around)? Ta.
