1) The PS3 outputs PCM decoded from TrueHD and DD correctly. That means, if we have a digital recording at say 50 Hz (any frequency that the LFE channel can carry), applied to all 6 channels (5.1) at the same modulation level (can be 0dBFS, -20dBFS, don't care as long as all channels are the same), the PCM signals coming out of HDMI are all uniform. (This is the same channel gain relationship as the PCM from any 5.1 bitstream when decoded inside an AVR, prior to any post-processing such as bass management.)
2) There are no gain trims in any channel.
3) There is no fixed bass boost or cut in the LFE channel.
4) There are no high-pass or low-pass filters in any channel.
This is how HDMI PCM output is supposed to be. If the Panny does something different, like apply -4dB to LFE, that is unfortunate and not easy to fix in the AVR.
