Neoseeker has posted a review on the Philips Acoustic Edge PSC 706 sound card.
Philips believes this card sets itself apart from the SBLive 5.1 and the Santa Cruz because it is the very first card to enable true 5.1 audio from ANY source.

This technology essentially extracts positional information from a stereo stream, and maps it to a 5.1 or 4.1 setup to produce discrete and distinctive channels of surround sound. This is a pretty good pitch, because right now all surround sound cards will output the exact same sound on the front channel as on the rear channel, so that the rear channel is nothing more than a mirror image of the front stereo signals.Read more
