I had a dark sounding tele (yes, that is possible) with some compensated brass sadles.
I thought about these sadles as expensive, but I didn't wanted to change my guitar because it had also some positives I liked very much. So I bought these sadles.
Ok, after installation I was not negative, but a little underwelmed. Yes, the sound was improved.
Next day, I forgot the sadles and started playing the guitar:
WOW!
Yes, the change is subtle, but indeed not only better highs, but also better dynamics and things I cannot describe in words.
It feels as if I am playing a more expensive guitar with these sadles!
