Doug said: The Mac Platform performed more or less as promised by Atomic Audio Labs, providing a worthwhile increase in sound quality across the entire audioband. While the cost of the Mac Platform may seem high, the cost of the components and accessories of a good high-end system could very well result in the Platform being the least-expensive device in the rack.

The gist: Improve the sound and appearance of your Mac Mini.
