Think about that sentence for a minute. You indicate that your reference is live music.
Do you find listening to live music fatiguing? If live is your reference you can't get much more "accurate" than the live performance.
(However, all bets are off if you're talking non-acoustic music since what is often found on recordings doesn't actually exist "live.")
Assuming that live music does not fatigue you, that means there is something decidedly not accurate in your current setup.
You've got some good suggestions above. Another one is I find many "audiophile" systems far too bright in comparison to live music. A bit of extra "oomph" in the upper range can make a system sound more detailed. This in turn is easily confused for "accuracy" when in reality it is different from the live performance.
I'd recommend that you borrow or buy a real time analyzer and get a good picture of your in-room response. It might surprise you. You've got enough invested in your system that it is certainly worth checking out.
Just one more option to add to your list.
