There is a big difference in sound quality between the LX91 and the PS3, the sound on the PS3 isn't bad, that's not what I want to say, but you have too many settings on the LX91, that's why he is better. By the way, the only difference with the LX71 and the LX91, it's just about sound, nothing else, the picture quality is exactly the same, with the same settings. And the PCE 5.1 via the PS3 is not as good as the LX91. But you're right, let's back to the pictures, unfortunaly I dont know how take a good picture... I will try and Post some if they're not too bad.
