Those engineers operating the studio gear are putting that sacred "absolute sound" through miles of wires, pan pots, addled brains, unclean tape heads, unclean bald heads, digital manipulation, badly tuned pianos, and personal tastes just like the home hifi geek. The only way around it is to hire musicians to form a circle around you while you lie on the floor after recently having cleaned your ears. Preamps sound however the designer wanted them to so it's up to you to decide what sonic manipulation you prefer. If you're lucky you can enjoy music...or spoken word...or dump trucks backing up...lucky you.
+1, An effective dose of reality nicely summarized.
