I'd be happy to send you my toenails if you have an address.
I do understand circuitry and sensory testing enough to recognize what makes sense and what's clearly nonsense. Someone has filled your head with nonsense, and removing it will require firm measures.

Opamp changes can only make no difference or degrade performance. The audiophile custom of whipping out a credit card, dropping in parts willy-nilly, then fantasizing about the miraculous changes in the sound is a sadly common one.
Reality: they are not interchangeable jelly beans, and a circuit optimized for one type will underperform if you drop in another. At best, it won't be any worse. And any sound changes are vastly likely to be imaginary.
Since the designer of some of the best opamps ever made is an active participant here, you might ask yourself why he doesn't play this game.
