mdrew - I was wondering the same thing regarding the PS3 passing decoded LPCM vs. having a preamp/receiver do the decoding of the raw bitstream. I don't have another Blu-ray source to experiment, but I have done the same with TrueHD tracks on my Toshiba HD-XA2 HD DVD play and I honestly can't tell a difference. Regardless, I agree that the TrueHD track on the Dave Matthews Blu-ray is the best sounding recording I've personally heard.
