I love Macs, and use them for everything but my music server. There are different schools on what or why computers, player programs and file types sound different. Although the general consensus is that noise is the primary issue, there appears to be different views as to what noise to deal with- into the computer, out of the computer or within the computer.
You have mentioned CAPS, and that is one option- a low power motherboard that clips along at a steady speed with isolated USB. Another option, and the one I have chosen over time, is the high power pre-processing that then nearly shuts the computer down as the files play using XXHighend as the player program.
FWIW, I wish I could have stayed with Macs, but XXHighend on w7 sounds the best hands down. It takes some work, but it is worth the efforts. I have used every player on Mac and a well respected Linux based appliance server (Auraliti- similar to a CAPS).
