Bass and Treble Dials

It seems every high end audiophile quality preamp/amp comes with no bass/treble dials. There is no way to adjust the sound coming out of the system other than by adding, removing or replace the audio equipment components... such as the needles, tubes, cables and etc etc. I wonder what would be a real reason behind of not having the treble/bass dials? While it might be a simple question but I really don't know the exact answer. I only guess that it is because the adding the treble/bass dials will unavoidably make an electronic circuit more "complex" which would go against a whole concept: "the simpler the better" or "the less is more". Am I correct in my assumptions?

You could always get a decent parametric equalizer and see how it sounds in your system. All of them have bypass capability so you can quickly A-B the sound with and without the equalizer in the chain...

Sputniks,

Adjusting treble and bass can do more harm than good since nature of recording deficiency (if any) is more complex than just treble and bass.

It shows in market demand - no tone controls in most high end systems but tone controls in every low end system - they need them to fix lack of transparency and neutrality.

Low end speaker is a good example - limited low end with pronounced hump at mid-bass. On recordings with a lot of midbass it will sound better with less bass but on recordings with low bass it needs more bass from an amp.

I don't have any desire to adjust tone (or balance) but remember doing it constantly with low end system.

Accuphase, Mcintosh, and Van Alstine offer them in many
of their preamps, FWIW.

You are correct with regard to the signal path. And tone controls can affect things such as imaging, soundstage, etc as much other things (distortion, purity, etc).

I also want to suggest to you that there are other ways to affect the sound in your system, other than adding or removing components. In fact, some of the best ways include room treatments, speaker position, and listening position. Experiment with those things - a lot - and you may be surprised how much better your system can sound.

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.
