I'm gonna retire my 2.1 computer speaker set-up & just ordered the AudioEngine A5 powered speaker set. I'm now looking into whether getting a Digital to Analog Converter to put between my MBP & speakers will make an appreciable difference for me. I am NOT a musician, and will not be making recordings; this is simply for listening to music through iTunes (& occasional movies w/ VLC). About the only genere of music I won't listen to is Country (but mostly I lsten to blues, jazz & alt rock). Someone suggested an Apogee Duet, & even though I can afford it, it seems a bit pricy given that it seems to be targeted towards musicians rather than a wannabe audiophile like me. Any opinions out there whether I even "need" a DAC, and if so, any specific suggestions?
