The Story Of My Life

When I was young, I wanted to hear some really good speakers.
Pretty soon, I wanted to possess some really good speakers.
Eventually, I tried to design and sell some really good speakers.
But now, I just hope I can lift some really good speakers. 

A Few (Relatively) Recent Interviews

Migrating some old blogs over here. 

The spread of Freud’s thinking put the final nail in coffin of "insightful" art, as photography had to "representational" art.   The dominance of conceptulism in the 20th Century, including the more intellectually coherent forms of "abstract" art, were the direct result.  It gradually became impossible to an educated artist to work without some degree of self-analysis.  Given the somewhat ubiquitous endgame of successful psychoanalytic introspection, the territory was soon well-mined by the surrealists.  
Artist became increasing focused on the primacy of the process, not the piece.   No doubt, this was also influenced by the widespread adoption of almost metaphysical frameworks in the natural sciences, and by a general trend away from materialism in intellectual circles.

All Caps, All The Time.


From an Audiokarma post of mine.
Here’s one lone contary voice:
If you like the speakers, I suggest you replace that big cap with a standard bipolar electrolytic from Madisound or Parts Express.  Here’s why:
That old style cap probably has a series resistance of several Ohms, even when new.  That resistance will definitely be part of the crossover shape and frequency balance of the original design.  If you put in a film cap with very low resistance, the level of the driver it is connected to could easily go up or down by a 2 or 3 dB.  That’s a lot of tonal change. 
Of course, I know that many people like to replace their electrolytics with film.  The trouble is, 9 times out of 10, what they are doing is boosting the tweeter level, and believing they’ve added more "detail."  (These sometimes the same guys who would have a siezure just looking at an equalizer…)
So, sure, if you don’t like the speakers, of course, mod them!  Why not?  But, if you want to restore them, totally changing the crossover by changing the type of cap won’t get you there.I think you will find that modern electrolytics are MUCH better than the generation that is in your speaker, anyway.  If you feel you must use a film cap, consider adding a small resistor in series with it to maintain the balance of the speaker.  How much to add is best determined by listening.  (Hey, resistors are really cheap.)  I’d figure somewhere between 0.5 and 5 Ohms.

Wire reviews are a waste of time

By Ken Kantor

September 14, 1999 — I’m really over reviews of speaker wire. Generally based on technical misunderstandings, the information they include almost never translates from one situation to another.

And to the "wire-makes-a-big-difference-and-I-have-better-ears-than-you crowd": Spare me the vitriol. Been there, done that, got a T-shirt.

Yet another intelligent and well-meaning audio lover becomes convinced every few minutes that wires play a big role in getting high-quality sound. And why shouldn’t they?

These folks are consistently told that there are great differences between the various types of wire. It becomes the hot topic of social gatherings, ("My wife even asked me what I had done to my stereo — before I told her about the new cables!").

Don’t even go there

Most hi-fi reviewers are self-assured of their ability to perceive and categorize obvious and consistent differences between brands of wire. No matter who you are or what your credentials and experience may be, if you minimize the importance of wires in the sonic equation, you are ridiculed for your lack of accurate hearing, for the quality of your system and for the conservatism of your viewpoint.

You really can’t win. For instance, I have friends who enjoy debating about politics, religion and ethics. Yet as soon as I start to explain the basic, known science of audio cables, they turn red and throw things. In audiophile circles, you could promote the benefits of molestation with less scorn than you get from downplaying cable differences. How "politically correct" does one have to be?

Maybe it’s a basic yearning to experience the unknown. It was Einstein who said, "The most incomprehensible thing about the world is that it is at all comprehensible." In short, weall love a little mystery in our lives. But if there is anything in audio that is well understood, it is wire.

Unbind your mind

That doesn’t mean all speaker wire "sounds the same." It does, however, mean that the way they work is not magic. Open your mind and your ears and take a minute or two to understand the real deal. Once you do, it will become clear why the prevailing popular notions are wrong. To do so, though, you must first let go of your preconceptions.

Any cable interposes an electric circuit between the amplifier output and the speaker input. Whatever the cable is — and however it is constructed — the effect it will have on the sound of your system boils down to three, easy-to-understand factors: resistance (R), capacitance (C) and inductance (L).

If these three factors were all equal to zero, the cable would indeed have no effect whatsoever on the signal. Given that this is never the case, there always will be some influence — perhaps audible, perhaps not — exerted on the signal. Exactly what sonic effects a given combination of R, C and L will yield depend entirely on the amp and speaker used. One speaker/amp combination will get a bit brighter with more capacitance added; a different one will sound duller; and a third will be virtually unaffected.

Likewise, the effects of resistance and inductance are impossible to generalize. What’s more, all three intermix. For this reason — and contrary to modern "wisdom" — wire brands cannot possibly have any truly inherent sonic character. To speak of a "smooth" or "detailed" cable is incorrect and misleading. The difference in sound is all in the matchup — and reviewers should know this.

Studies have shown …

The fact is that, over the years, there has been much research and investigation into the sonic effects of speaker cables. Sure, some of it is sloppy and virtually worthless. The majority of professional studies, however, have been conducted with great care by qualified audiophile scientists.

What has consistently emerged from these studies is that although speaker cables sometimes influence the sound, they usually do not. Even the most biased audiences seem to lose the ability to distinguish between different cables when they can’t see what they are listening to. When you take the time to track down and analyze the apocryphal stories about miraculous wires, you find that people moved their speakers by an inch or two, or perhaps they absent-mindedly cleaned the amp terminals before hooking up new wires.

Carefully eliminate these subtle variables and wires start to sound surprisingly similar. Not always perfectly identical, to be sure — but not responsible for the huge improvements in tonality, depth and imaging that many people have been led to expect.

What to do?

In all cases, the lower the R, C and L, the less the sound will be altered. Accordingly, you should use heavy wire and solid connections. It does not mean you must use expensive or brand-name wire. Actually, heavy zip cord is pretty hard to beat for signal neutrality.

In fact, zip cord is not just OK, it’s better than much of what is being sold today (that is, if accuracy of sound is your goal). Transmission lines? Characteristic impedance? Skin effects? Risetime? Get a clue! These terms are meaningless when applied to audio. The wavelength of a 20 kHz sound in a speaker wire is several MILES long. That means that audio frequencies are much,much lower in frequency than the point at which detailed construction aspects of the wire are going to have any influence on the signal — so much lower that it isn’t even a gray area. Don’t believe me? Ask your local physicist, the one who doesn’t work for a hi-fi company.

Human hearing is very much subject to conscious and unconscious influences. If even you can’t be completely certain of what you are hearing, how could anyone else? By all means, feel free to succumb to whatever mixture ofillusion and reality feels good when choosing your cables. Just take all the stuff you read with a big grain of salt. It isn’t borne out by scientific research and, more important, it isn’t supported by controlled tests — regardless of how persuasive and seemingly logical the advertisements and reviews may be.

Trusting your ears sometimes means learning to hear a subtle difference or discovering a hidden cause. More often, though, it just calls for an admission that you’re making an audible mountain out of a sonic molehill. Hey, it can happen; the majority can be wrong.
