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!

Atmasphere, how about this. Some quality tube preamps have a tape monitor loop. Insert an equalizer in this loop, when you need it simple engage the loop, not used disengage, not much harm to the signal there. Or connect a quality sub to the extra pair of outputs on the preamp if they exist which would be the least offensive. I'm trying to give you more bass when needed. Good, well defined bass one way or another adds realism, emotion, & impact to some music.
While some may note lack of bass, the majority of complaints are about harsh highs. This is most often the result of the recording IME. I've yet to hear a piece of equipment that completely corrects boosted highs and compressed recordings. If someone wants the accuracy of these recordings, more power to 'em. Myself, I'd prefer to roll it off with a tone control.
Wireless200, as time has gone by and my equipment has improved, I have found that many 'bad' recordings were exacerbated by problems in the equipment. For years now I have used that as a yardstick. The playback should be unperturbed by a bad recording.

The result has been that many of those recordings that I had thought were 'harsh' and the like turned out to have a lot of energy, but not actual harshness. A good example is the Nonsuch recording 'Village Music of Bulgaria'. A stunning recording, one that in the old days I thought was really harsh. It isn't- just energetic, and amazing.

Phd, our preamps have such a loop. I've been thinking that a simple tone control system might be more in order than a parametric as the injection of the circuit would be less profound. Some LPs have a 6db rolloff at 100Hz and below due to EQ errors in the mastering process. Sure would be nice to sort *that* out :)
