DAC for Use w/ AudioEngine A5

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?

 

Thanks for the explanation & suggestions... Obviously I thought the Duet would be way too much for me given the single application I would use it for (playback via iTunes). I simply misunderstood... I have a help thread going over at Head-Fi as well, and am getting similar suggestions (incl. the Chinese DAC). I'm gonna try the A5's w/out a DAC (direct to the optical/headphone out of my MBP) for a while to hear what it sounds like. More than likely I'll pony-up for a DAC (& probably a sub & amp) later on...

 

I ended up getting an Apogee Duet, and it worked very well. I ended up upgrading, however, & sold my A5's a couple months ago. The Duet (which I still use--running it to an integrated amp & passive bookshelf speakers) really improved the sound--to me, it was a "significant" improvement, YMMV.... There are a ton of DACs out there.....
