I haven't had the luck to fly an A10-C, so I am not able to say if this sound modification is more or less realistic than before.
On the other hand, just knowing that there has been a change will do wonders for my sanity! Thanks for linking the other thread.
It is true though, that in the absence of actual feelings of acceleration and thrust, that sound was extremely useful. And I just loved it, i mean musically.
I guess it all boils down to a matter of taste, since we're in a simulator.
Thanks a lot for all these good answers! Godspeed
