Why do all Mahler recordings seem too bright?

Yes - I may be exaggerating but I haven’t yet found any recordings of his symphonies that properly balance the extra treble energy that are often part of the dynamic swings.  Part of the problem may be that I’m not sure I yet actually “like” Mahler’s music though there are moments that are exquisite.  But, I can’t get through a whole piece because the recordings hurt my ears.  

As a side note - I have been on both sides of a microphone - having been a musician in the past and also having recorded/mixed a number of orchestral concerts at a performing arts center.  Pre-pandemic I would go to orchestral concerts regularly. So - I do have at least some reference.

I have some recordings (they were given to me) that are positively unlistenable (a DG recording of his 5th may be singularly the worst recording I’ve heard).

I thought the hi res versions of San Francisco by MTT might be the ticket.  While better, they still seem too bright and harsh to me.

Perhaps it’s my system that’s too bright, or perhaps something else is going on but I’ve plenty of other classical music that sounds better. We’ll recorded jazz and acoustic, too. 

Of course I can find poor recordings in any genre, but I’d welcome recommendations from my fellow forumites of some Mahler recordings that I might try.  I’d love to be able to listen to the closing moments of the 2nd at reasonable volume - without cringing.
