Ok two things I want to mention.
First off, there are only quiet bits if the CM dispatches too early. If they dispatch it (properly) the drop shaft VVC will already be up at the 5th dimension floor waiting, and the AGV never pauses, leading to almost no quietness before the drop sequence audio starts. It also highly depends on when the starfield door "splitting" sound plays, because the rest of the sounds after that tie in to when that sound plays. Currently it plays 2 seconds too early on Foxtrot and one second too early on Echo, but there were times in the past where it plays after the doors start to open, which I even found videos of where the drop sequence starts right as Mark Silverman says the word "Terror". After mid-Tower3, they added a mechanical sound when the AGV enters the drop shaft, which with the newer speakers put on in late 2017-early 2018, was pretty loud and had a deep drone to it when entering the drop shaft, but unfortunately is quiet now because of the whole speaker fiasco since Spring of 2019.
Second off, that whole simulator platform thing is a complete hoax, I have proof from behind the scenes videos that it is just a standard VVC, the same drive system as DHS's version.
This is my rating for all of the ToT's(excluding MB): DCA<WDSP(Orig)<WDSP(New vers.)<Tokyo(Theming and effects wise mainly)==DHS
