Complex music, orchestral, massed voices, etc. is difficult on many systems. That’s why VERY few show demo rooms use this type of music, instead relying on much simpler stuff. The fact that you are getting glare on some crescendos may be due to the fact that you are overdriving the amp or speakers. If the music still glares when you turn it down, it sounds to me like it’s in the recording. Try listening through headphones to see if it’s the recording.
If that doesn't work, do what 95% of all audiophiles do - just listen to stuff that sounds good. Sad but true. Denials to follow.
