I am surprised that no one has mentioned evaluating the signal chain past the pickup/preamp. i.e. cable, external preamp/EQ, amplifier, DI box, soundboard, etc.. I have used all generations of the ES and each sounds as good as the other. Changes have been in power supply and grounding. Alot of personal preferences state here, but they are just that, personal opinions. Taylor has not become a market leader by making inferior products. The other variable is the player themselves, and their level of playing expertise/techniques.
