Probably for a similar reason that most cables change the tone. I doubt that you will get a satisfying answer.

dont like it? dont use it! there are people that like tone controll (like me ) but most of the guys here dont like it though so most of the circuits of "hi fi" pre amp u'll find here have no tone controll

Hi,
Many commercial amps have tone controls to allow the user to mistakenly believe they can alter the final sound to take account of the dificiencies of their system.
I believe that you should choose a system that best meets your needs and listen to what the recording producer put on his recording without adulterating it any further. ie. no tone controls for the last 28 years.

Seems like most of the upper shelf systems don't have tone controls on the pre amp but many use some type of EQ, be it graphic or parametric to ballance out the room. Sometimes with well designed tone control circuitry you can do a similar thing.

Blessings, Terry

Some preamps are just poorly designed.
You mention a change in the bass and mid.

If you will better describe what you are hearing, we may be able to give better advice.

Why no tome controls? Possible reasons include:

A- Experience with poorly designed controls sometime in the past. Audiophile logic (and I'm as suseptable as anyone) tends to over generalize -- if something was bad once, it must be dad always and under all circumstances.

B- Over optimistic expectations. Tone controls can't cure all ills, therfore they are a bad thing. Related to A, above.

C- EQ is more effective. The benefit of well executed EQ goes way beyond what tone contols can do.

D- Belief in minimum components in the signal path. Capacitors are especially heinous in some eyes and tone controls tend to involve caps.

E- More people are going to multichannel pre-amps where tone contols are hard to use. (Just contemplate adjusting tone controls in a 5.1 system - where do you start?) Result may be we have come to expect the lack of tone controls.

oh cmon
tone control is ment for changing the tone
tone control is the same as graphic eq with less bands
thats what i've found http://sound.westhost.com/project02.htm
u can make it with no tone control if u want to

why no tone control in hi end systems? well because some old guys belive in stuff like directional cables , digital audio sux , this super op amp is better then that ...... ugh

those guys know that in the studio the signal goes through millions of caps and op amps and mixers/tone controls / eq's and all that and they still think that a small cap in the signall path will make the sound worse


also music recorded on the cd is recorded with less bass then there should be because the bass signal is much bigger then others , for better resolution u gotta reduse it .........snr is limited

btw sam9 in 5.1 most of the time they use digital tone control
look for the facts ........good luck







THE TRUTH IS OUT THERE






LOL

Actually, I'm not sure I've ever seen a tone control on a 5.1 AVR or preamp/processer regaredless of wether it is high end or low end. I'm sure there is one somewhere but it's unusual. Maybe there's a conflict with THX certification.

Personally, I don't use tone controls because I've got an EQ unit that is more satisfying so far as room correction goes. And as far as making a recording more to my taste I'm a bit hard nosed in that I'm not inclined to correct short commings of the end product but fior better or worse form my opinions therefrom.
