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?

Okay, I think I figured out what I am going to do. I am going to use a Macintosh Powerbook as my interface and drive, and add a firewire hardrive to store my music in a lossless format. The only thing left to consider is, how do I connect the computer to the pre-amp portion of my integrated, with good D/A conversion in between? Thus far the Apogee mini-dac with USB seems like the only (and possibly best) way to connect straight from the computer into my pre-amp while maintaining a very high quality of sound. Any other ideas?
Pardales, my quick check of i-retailers indicates the Apogee mini-DAC will set you back about $1.2K. I use a Waveterminal U24 ($160). If you went that route, it would leave you a cool $1K to find a good DAC that could also be used for other things... $1K on the used market almost gives you a Theta Gen Va, for example, or a Birdland. I haven't A/B'd my Waveterminal/dCS set-up against the Apogee, but I still think the U24 route gives you more ultimate flexibility. The USB input of the U24 will let you put the device right next to the DAC and limit the length of your coax digital interconnect...
Pardales - There are also the two USB DAC's offered by Wavelength, The Cosecant and The Brick, as well as the Grace M902. Of those, the Apogee is certainly the least expensive. I'm pretty sure there are a few others as well.

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.
