I am fascinated by audible feedback. I can hear the blade in my Gillette Aristocrat cutting through the whiskers. It adds a lot to the whole experience, although I'm not sure why. I never noticed any audible feedback with a Mach3. Why is that?
My RazoRock SLAB has amazing audible feedback.
I think this is part of the equation. As is the construction of the razor and the particular blade. I found shaving today with a Treet Platinum SS more "audible" than with a Gillette Nacet Stainless. Both with a Gillette Slim adjustable.Perhaps it is not that it is louder per say, maybe it is just that we are paying more attention to the act of shaving that we are able to hear it easier.
