Bass and treble levels

Over the last 40 years I have never used them. I have always tweaked my room and speaker placement. However, now I have a new room, speakers and power (McIntosh) units. I am currently using a McIntosh c47 preamp. After dialing everything in the sound was very good. However, it was still a bit bright for me. I bumped the treble down 1 notch and it sounds better to me. I don't think it was the amp/preamp, I have used McIntosh forever. But with the new speakers, new room and my older ears things have changed. I would say (for me) perhaps a small change (knowing that tone controls affect a pretty broad range of frequencies) may help.

I think it's important to note what we are sensitive to as well. 

I like tone controls, but my current pre's tone controls definitely dull the sound, even when set to neutral. 

Sadly, the design and parts quality of tone controls has really diminished. 

So this is gear dependent. I'm sure others may totally not hear this issue at all. 

So, I don't think there's one answer, except to please yourself, and pay attention to your perception in long term listening sessions. You'll eventually become your own mastering engineer and decide what's best.

Gotta' agree with you about the quality of current tone controls. . Unfortunately, some of the earlier CD recordings certainly need treble cut.

Great point about early U2 and some 80s music from Eric_squires. There are some albums from that era I would love to hear reconfigured for our modern ears, but I guess that can't happen without recutting the masters. 

Many of you have seen this, but here is a great write-up of how recordings changed over time.
