lpcm or bitstream for bluray?

I own a ps3 and have a Cary Cinema 11a on order which has hdmi 1.3. I know the ps3 will decode hd audio internally and send it out as lpcm. Is the ps3 sending an anolog or digital signal? Where is the actual d/a conversion taking place? Is there any advantage to having a player that outputs bitstream?

Digital. PCM is a digital signal.

In the pre/pro.

Yes there is, if your pre/pro can process the bitstream being sent. Typically a pre/pro has more processing capability than the player does, so manipulations specific to your environment (bass management, digital delay, digital EQ) can be set to desired parameters. These functions may be included in the player's feature-set, but they are often sharply limited in versatility relative to what a good pre/pro can do, again assuming that the pre/pro can process the bitstream the player is sending.

  If I send lpcm out of a ps3 via hdmi to my pre/pro, which in this case will be a Cary Cinema 11a, I will be limited in what I can do with digital bass management and eq software compared to a player that will send dolby hd as bitsteam?
  - It depends on the capabilities of your pre/pro (nt) - racerguy 11:47:44 06/28/08 (0)

LPCM is digital. D/A conversion is the the processor in this case.

  From what I have read, lpcm should sound just as good as dolby hd or dts master. It also seems that none of the eq software in the new pre/pros can be aplied to dolby hd or dts master but can be apllied to lpcm if I understand correctly.
