This aircraft is certainly a thing of beauty in how it's been implemented in the simulator. Sometimes, I get a bit of an unnatural break or volume-jump in the sound during startup, when one sound stops and another kicks in (which is more akin to older simulators where the audio was much simpler), but it's not all the time. Not sure why.
There is one developer that maybe just has the edge in the natural-sounding/dynamic startup, but we really have it so good these days thanks to the cream of the crop of add-on developers, that we have little to complain about. Yet still we keep asking for more details and depth...
