Music from hard drive better than CD?


Hi folks, I'm considering to buy a MacIntosh G5 for using it as a source in a high quality audio system. Will the Mac outperform the best CD-transport/DAC combo's simply by getting rid of jitter? It surely will be a far less costlier investment than a top transport/DAC combo from let's say Wadia or DCS, hehe. What is your opinion?

Thanks Edesilva and Jax2. I might go with the inexpensive wavelength to begin with and see how it sounds. This is all a bit of an experiment to see if I even like interfacing with my music in this way. If I like it I may then go for a more serious DAC.
An even less expensive option, if you are running a Mac, is to use an AirportExpress module (about $120) which has an optical output that streams raw data and bypasses the DAC (you'll need a toslink cable). You can stream your music from your computer via either an Airport card or other wireless device, or via an ethernet cord directly to the AirportExpress. The optical output of the AE runs to your DAC and VIOLA! If you are looking for an inexpensive way to experiment and see if it suits you, that might be an alternative worth considering.

The Apogee Mini-Dac has a Big Ben clock in it. I used an M-Audio Audiophile USB Dac before the Apogee and the Apogee Mini-Dac is many jumps in quality better than something like the M-Audio. Completely different ball-park. I also used the M-Audio just to convert the signal to SPiF so I could plug the computer into a Proceed AVP2 and use the Proceed's DAC. Again -- the Apogee USB Mini-Dac sounds way better. The computer plus Apogee just sounds great. Natural, detailed, organic, not digital sounding at all. I am extremely happy with it.
Jax2: You are right that the Airpot Express would work, but, I don't currently have a DAC. So, I do need a DAC of some sort first.

Rsbeck: If I decide I like interfacing with my music in this way, I will probably go with something like the Apogee. I might trying something a bit less expensive first though. If I get to the point of auditioning DAC's I will definitely give the Apogee a try.

It will be a few weeks before I get everything set up and I will report on my experiences throughout the process. Great thread! Thanks everyone.
Question, you rip a CD to whatever file format desired. What happens to songs that flow one into the other, such as the 1st two tracks on Pink Floyd's Dark Side of the Moon? Can the CD be ripped as one image (WAV) and played back through iTunes or Foobar2000 and still have access to a track list?
