It took me a good many years until I found out why "higher end" gear didn't have tone controls. I always assumed that many factors denoted a need to adjust the sound. I then discovered that having built a system with care and a great deal of synergy, I now hear far more of the music. There are underlying passages I had never even noticed and instrumental lines that had hitherto eluded my ears. Ergo, there was no longer any need for adjustment and certainly zero need for things like balance and tone controls.
But that's just me.
