Tone Controls can be so nice.


Of all the ways to tame, tighten or tone the sound of our systems, cables are usually the first to come to mind. Preamps, amps, source and speakers are all chosen for what and how they contribute to the sound and each affect the other in ways that confound, amuse and satisfy.

Anyone who's paid even scant attention to what I like in my system knows that I've always wanted to hear further into the recording, extracting as much as possible from those shiny discs and not pay the price of loss of tone, richness or body. From sliver ICs to power conditioning and boutique fuses, each step has gotten me closer, revealing more detail, nuance, air and realism.

One day while listening I chanced to look at my Marantz PM-15S2b and it dawned on me that I hadn't tried the tone controls since the first time I tried them when new. I didn't like it then. Just switching it on without adjusting the controls it was evident there was a difference for the worse when used.

Time can do funny things. It may be due to something as simple as break in but when I engaged the tone control setting and adjusted the bass a tad (1 1/5-2db) a lot changed. Everything I liked about what I already have was fleshed out some more without a single, negative drawback. Tone improved. So did body. Percussion was easier to believe be it wood, brass, etc. Vocals had more chest and in the room presence. Piano had more weight, guitar more blues and twang (steel easier to tell from nylon). Even decay took on a different quality since the lower portion of the notes had more presence which led to a longer, more believable decay. Decay used to be the in the realm of the higher notes, the lower ones foreshortened, and now decay is across the spectrum which makes piano, upright bass, anything in that realm all the more authentic.

I dialed it back to just about a 1db boost and still had that magic. Nothing was shelved back, hidden or muted as a result. Just fuller, like a really good tube setup with great see-through ability. No bloat. No smear.

It's too bad that tone controls aren't in vogue nowadays. Blame the purists and thank those that still use them (Marantz, Luxman, Accuphase, etc.) I'm not advocating some all out assault with extensive equalization but in my case the bass boost is just at the 50Hz region and covers a small, but critical range for folk like me. My Tonians drop off at 40Hz and the drop slopes well before that. That little boost is all it took to even the frequency playing field, so to speak, making it seem all the more real. This is not to say I didn't have bass to begin with. What I did have had texture, detail, nuance but not enough force to have equal billing in the presence department.

If I had speakers that extended lower, all of this wouldn't matter. In my case it did. This is not to say that everything is better with tone controls but is some cases, certain recordings can use that little bit of boost and some systems, like mine, can benefit from it. It's been only a few days since I've done this but I've yet to tire of it and find myself loving what I'm hearing. Who knows?

All the best,

Tubes,cables,phono cartridge,etc. are all tone controls in their own sort of way! Anything that you change will add some coloration to the sound so tone controls are no different!
Every form of EQ or tone controls out there, just from a technical standpoint, have their own set of advantages and disadvantages when it comes to how they can affect sound quality. Phase or noise problems and not being able to do much for time-domain problems and all that. It all gets thrashed about a lot. But, what so often gets overlooked is that, especially for those who have actually logged some time with EQ or tone controls (I've done so with EQ for many years now), is that the advantages - even if only within the context of a particular setup - can often end up outweighing the disadvantages, despite the limitations. Hearing is believing. Their longevity as a handy and rather flexible tool to rely on, perhaps particularly as a stopgap measure, has always impressed me. And often the stopgap app is so successful at forestalling an otherwise significant purchase, that it can easily come to be thought of as permanent. But, I do agree with Shakeydeal: "If you like them, use them"!
Each of us has our own realities. If you like tone controls then there you are. It is challenging enough to optimize audio amplification components through keeping things simple, and more additions (remotes/displays/headphone facilities/etc.) complicate doing so. While some audio enthusiasts adhere to a purist approach, others place a premium on convenience, while some lie somewhere in between. Your reality is what matters.
I also agree. When it comes to tone controls, the self-aggrandizing purity of high-end audio recalls the famous Polaner All-Fruit commercial.

Our intelligence, progressive thinking, and overall utter goodness resulted in advancing so far over the heathen of yesteryear. We instead now employ phono cartridges, turntables, digital front-ends, pre / power amplifiers, loudspeakers, vacuum tubes, interconnects / loudspeaker cables, power cords, power conditioners, isolation devices, diffusion contraptions, silver bearing pastes, charlatan telephone exorcisms, etc. to salve the glare, soften the highs, flesh out threadbare lows, remove bass bloat, tame the room, and add two inches of height.

Do what you must. Spend what you can. Just don't ever permit two knobs into your system that defile the hallowed bass and treble. We must adhere to the absolute sound, you know.
I want to hear how the producer/engineer intended the recording to be heard. Equalizers and tone controls have no place in my system.
