>>the ps3 will decode hd audio internally and send it out as lpcm. Is the ps3 sending an anolog or digital signal?<<

Digital. PCM is a digital signal.

>> Where is the actual d/a conversion taking place?>>

In the pre/pro.

>> Is there any advantage to having a player that outputs bitstream?<<

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)
