I just replaced my SB Live! Platnium 5.1 with the Philips Acoustic Edge and it is much better than the SB card. The Thunderbird DSP on the Philips card is the only card that can output 5.1 sound from any stereo source, whether or not it is encoded for it. The live drive does offer more connectivity, but I never used it. This card also produces sounds more accurately than the SB card, and I can even play my games in A3D 2.0 even thought the card supposedly does not support it. It sounds so good with my Promedia's that I might pick up the 2.1 PM's and make a 6.2 system.....that should wake the neighbors for sure..:Q
