IIRC the AC-3 had its high frequencies cut off at a much lower point than the PCM. I think I still prefer the AC-3 though. Wondering if anyone more knowledgable could explain why the apparent filtering didn't have too big of an effect.

I took some spectrograms. The AC-3 5.1 track has a cutoff at ~14 kHz (due to AC-3 compression?), whereas the PCM 2.0 is full-range.

PCM 2.0:
