Are most DAC's compatible w computers?

I am using a G4 laptop out to a Waveterminal 24 ($159) and the Waveterminal directly into my integrated amp. The sound through the Waveterminal is at least as good the sound of my MAC changer (maybe a little better). I am trying to decide between the Benchmark DAC 1 and the Apogee USB DAC -- as a further improvement in sound. Any thoughts between these two DAC's? Using the Apogee means I don't need the Waveterminal, but the Benchmark has also received so much acclaim.

Thanks, Ckorody. You are right that a USB DAC would be a simpler path than adding a DAC via the Waveterminal. Are there any other USB DAC's worth considering besides the Apogee (without breaking the bank)? Thanks,

I just figured out that I can get lots of great radio through my computer as well. I can now sell my changer and tuner if I want. I am thinking about putting my money towards a really good DAC since my computer is turning out to be the heart of my system. Now that I have ripped my 500 cd's to computer, and have all the album artwork loaded as well, I can't believe I didn't do this sooner. I am rediscovering my music collection and listening to stuff I haven't listened to for years. It would not surpise me if we begin to see a lot of USB DAC's on the market very soon.

I think their latest is the U24.....at least that is what is currently on their interet site. It really is a nice product.
