The use of equipment as "tone controls"


Several times in my Audiogon reading and posting over the last couple of years, I've noticed this or that contributor commenting along the lines of: "You shouldn't use your amp/cables/cartridge/whatever as a tone control."

I assume what this is supposed to mean is that there is some absolutely correct sound out there, and we ought not have audio equipment of any kind that deviates from that absolutely correct sound.

I might be able to buy into this if we were listening to live instruments (although their sound is, of course, affected by the space in which they are played, the position of the listener, etc., so is not itself "absolute"). But we're not listening to live music. We're listening to recordings. There are microphones, cables, recording equipment, mastering equipment, storage medium, etc, all of which come between us and the original sound--not to mention the taste and perception of the engineers, producers, etc. In that sense, what we hear coming out of our speakers is all illusion, anyway. And the illusion comes in quite a few "flavors." On one system I had, Bill Evans at the Village Vanguard sounded like he was in my living room. But Leonard Bernstein conducting the NY Phil in the early 60's was so shrill it made me run screaming from the room. In my current system, Bill Evans doesn't sound as "right there" as he used to (now I'm a few of rows back, yet still quite happy), but Leonard Bernstein doesn't make my ears bleed, either.

How did I work that? I experimented with different equipment. I used the equipment as "tone controls" (I guess). It's all respectible equipment: ARC, VTL, BAT, Cardas, etc. Maybe it reduced the "accuracy" of the reproduction of Bill Evans, but it increased the "accuracy" of the reproduction of Leonard Bernstein. Maybe. But who knows for sure?

We all tailor the sound of our systems to suit our preferences. What's wrong with that? And, most equipment has it's own sound character. That seems like a good thing, to me. It allows us to tailor our sound.

Now what we REALLY need is a good set of tone controls on our fancy pre-amps, so we can really tailor our sound!

Food for comment?

"Then I realized that everything sounded not only good, but practically the same"

Glenn Garza, could you elaborate on this statement? I think you are saying that no matter what recording you choose they all sounded good but similar and no venue ambiance difference was noticable?

I personally will take slightly colored system as compared to tone controls or an Eq. Too much fiddling and you could change tonal and phase correctness pretty fast.
Jafox,

I agree with you 100% about about the dangers of using an EQ or tone control to compensate for inadequacies in the equipment. However, the same could said for swapping cables or amps to try and fix a harsh sounding speaker. Or selecting a speaker with extreme high sensitivity but bumpy frequency response in order to make up for an amplifiers lack of power. There are "destructive solutions" everwhere.

an equalizer might be fine for a Walmart rack system but beyond that, it would be my last option

Perhaps you are one of the lucky few with an absolutely perfect acoustically treated room and no minor room modes that can be improved upon/mitigated through the judicious use of a PEQ or pre amp tone controls. We mere Walmart mortals can often benefit from judicious application of some tone control...
The comments above indicate some misunderstanding of the recording process.Almost uniformly recording studios use equalizers.The Cello Audio Palette was primarily used by recording engineers,it's use in the home system does not detract in anyway from the quality of the sound,and has nothing to do with room equalizers.Should you use a low quality tone controls or equalizer the result ay indeed be deleterious to the sound.Try it you will like it.
For instance, I once heard a very beautiful sounding system that was absolutely wonderful. Some recordings sounded as if the performers were in the room, but they were all great. Then I realized that everything sounded not only good, but practically the same. That cannot be right.

since all equipment is colored a stereo system is a tone control. you can't avoid coloration. all stereo systems are colored, since all components are imperfect.

the only issue is will the voicing be deliberate or unintended ?
