Just checked the manual for the HD-XA1 - it says TrueHD is downsampled to 2ch 48kHz over the digital outputs. This means you then use something like PLIIx to recreate the soundstage? In fact it says the 2ch for all outputs - even analog - so can the XA1 deliver multi-channel TrueHD output at all?

The XE1 - the Euro 2nd generation (same as XA2) says multichannel for analog and digital bitstream and 2ch for PCM.

The Sony BDP-S1 Blu-Ray player says 5.1 output for all outputs.
