Robert,

The difference between the 568.2 and the 568.2mm is the fact that the "mm" version adds a 6-channel digital input for high-res multi-channel audio. On the 568.2mm Meridian called this input "MHR Smartlink" and the original purpose was to provide the ability to connect the 568.2mm to the 598 player and provide the first industry approved multi-channel digital connection for DVD-A.
