When listening to those parts I'm surprised that I have never noticed their absence in the regular stereo track until you pointed them out, you have great ears hairy_hen! don't think I never would've been able to spot the hyperspace sound effect, it makes you wonder if there is more of these subtle differences we haven't spotted yet. What makes these two unique is that they are the only differences that are exclusively heard in the surround where as other differences was also heard in the main channels, hmm... they could very much be '93 additions but it's unfortunately impossible to tell.

Been going through the theatre recording with everything except the low frequencies muted, and while the bass is often indistinct and not of good quality, it does seem pretty similar to how they mixed it in 1993 for the most part, though not exact. I'll probably keep the LFE channel mostly the same as before, but I may change a few things based on what I'm hearing.

Tell us about what you're hearing. :) I'm curious.

I can't thank you enough for doing this h_h, love your attention to detail and perfectionism and your willing to improve on what already was awesome. Thank you! :) Can we look forward to some samples of your recent improvements? I'm dying to hear the results. Keep it up!
