The audio is great. The 5.1 track is awfully aggressive with some serious low end. My dual subs are being pushed. I'm honestly having more fun with the 2.0 1980 track in Pro Logic (not II, as my processor has both options): it feels so period accurate. Add THX processing and you'd think it was actually 1980! I've never heard Empire sound this good.

That's a serious endorsement, I really enjoyed the 5.1 but I reckon I'll have to give it another go-around with the 2.0 since it has your blessing!
