While the scale you're seeking may be more a product of the speaker system and the room, accuracy is more an issue of the recording IMO.
I'm a sixty-four old musician and my hi fidelity experience hearing is far from golden but I can easily hear many instrument differences on my car radio.
I have master tapes and files of recordings I've made before post production. I have little doubt these recordings played on your system would provide stunning reproduction.
I strongly suggest finding a decent live recording of a recent acoustical event you've attended and reevaluate your setup. I've had much better results using more reflective room tuning verses absorptive.
