Details of the difference between the PlayStation 3 Slim and the PlayStation Fat (phat?) are trickling in, and one of them is audio-based. Dolby TrueHD and DTS-HD Master Audio bitstream output to your receiver. I'm not a super-audiophile, but even I'm excited about these developments -- see, I use my PS3 as a media extender as often as I use it as a game-playing-machine, and I like to have the best components.
I'm going to defer to the techheads at Engadget for the detailed explanation of what this means:
"See the HDMI chip on previous generations of the PS3 didn't support bitstream output of the new(ish) high def codecs like Dolby TrueHD and DTS-HD MA. As such, the PS3 had to decode it internally before sending it over to your receiver via LPCM. A process that could garble the lossless audio depending on your setup."
No longer will I be plagued with garbled lossless audio playback! Of course, my receiver doesn't support Dolby TrueHD, so I'll have to drop a couple hundred bucks for a new one... and I might as well pick up some new speakers while I'm at it, not to mention having to buy a Slim itself. So yeah, I'm in for about a grand. But, man, Britney Spears will sound schweeet.
In all seriousness, it's been obvious from the start that Sony has the high-end in mind with the PlayStation 3... but my question to you is: Do you care about high-tech, high end aspects of gaming systems?
