Hmm... More testing is needed-so far I cant tell any difference between my Sblive & the Philips-tried UT, Q3A, Q3TA, Kiss psycho circus, Battle Zone 2, Giants & Star Trek Armada. The sound in Armada is messed up with the Philips -certain sounds are WAY to loud-sound is distorted. Giants seemed to sound better with the Philips. Maybe ill install MW4 to see how that sounds. This is definitely going to take a while!
