As we age, we have hearing problems. I do, although not all the time and most of the times can correct it, with some effort. Still, if we cannot hear well, what good is a high end audio system? Plenty good, if you ask me.

Ear focus

As engineers, we focus our efforts on what we can quantify by measuring, evaluating, and finding some form of commonality we can all agree upon. Perhaps the easiest is the ear.

We know what the average ear is supposed to do and we’ve got reams of research on the subject. We know its frequency capabilities as well as its maximum dynamic range and loudness levels. There’s probably not too much we don’t know about that appendage on the side of our head, and so it’s easy to give facts and figures on spec sheets as to how well our equipment’s going to interface with our ears.

Only, our ears are little more than sensors. What they interface with is our brains, and here we have far less knowledge of what we can and cannot perceive. For example, we have a general idea of how much and what type of distortion the average person can tolerate before they notice something’s amiss—but that’s not a firm number. It depends on the kind of music, the listener’s tolerance levels, and (maddeningly to engineers) people’s moods.

Our ears as microphones are an interesting concept but hardly how it works.

Tweaking vs. tuning

There comes a point in our stereo journey where we have to decide whether it’s best to tweak or tune. By that I mean we can embellish upon what we have or we can rethink that which isn’t working for us.

Much, I suppose, is dependent on whether or not we’re happy with the status quo. If we love what we have built, then perhaps it makes more sense to tweak in the hopes we can get something a skosh better. If, on the other hand, we’re struggling with sonic problems, maybe it’s better to rethink the setup.

For example, if we have a turntable high-end audio system and, for the most part, records sound great then we’re probably best advised to tweak the various tonearm/cartridge settings to compensate for minor problems. But, if we’re not getting the promise vinyl has to offer, then it’s time to rethink the system components—to tune by either equipment swapping or a radical rearrangement.

All too often I have run into systems tweaked to within an inch of their life with gadgets, process, bells and whistles, when what was needed instead was a radical tuning or equipment swap.

I think it’s part of human nature to want to make smaller course corrections than wipe a slate clean, but it’s also human nature to suffer through a situation because we’re hesitant to make the big change.

Tweaking, polishing, refining are small changes we can leverage to make what’s working better.

Tuning, replacing, rearranging are big changes we often need to make but more often than not shy away from.

To get to where you want to go, do you tweak or tune?
