I have a McIntosh 300 Music Server hooked-up to my Accustic Arts Dac1 MK4 using a Stealth Sextet digital cable and very happy.
I do use this when I don't want to just change one cd, I have not as of yet done any direct comparisons to my single cd drive unit but will down the road. I really like the Mac. very classy piece and easy to use. When I had any questions Mac was there to answer any and all which makes me feel confident in owning such a piece of gear.
