James Randi Posts $1M Award On Speaker Cables
elrond amandil writes "James Randi offered US$ 1 million to anyone who can prove that a pair of $7,250 Pear Anjou speaker cables is any better than ordinary (and also overpriced) Monster Cables. Pointing out the absurd review by audiophile Dave Clark, who called the cables 'danceable,' Randi called it 'hilarious and preposterous.' He added that if the cables could do what their makers claimed, 'they would be paranormal.'"
Unless you happen to love debunking the falsely-claimed-paranormal, you're probably like me and had no idea who the hell James Randi is/was/will be. Here's his Wikipedia page, here is his standing $1,000,000 challenge for a demonstration of true paranormality, and here is his Education Foundation (on "the Paranormal, Pseudoscientific, and the Supernatural").
Also, here's a video of him in action.
Misery loves company. Online misery loves unsuspecting random strangers.
Randi is a real character. If you don't know who he is, check out James Randi on Wikipedia or The James Randi Educational Foundation. One of his boosters is comedian and magician, Penn Jillette, whose TV show, Penn & Teller: Bullshit! he frequently appears on. He's ruffled quite a few feathers over the years by being the poster-boy for skepticism, especially with respect to "mystic" or "supernatural" claims, so don't expect there to be many objective takes on him out there.
All you need is an appropriate length of oxygen free copper cable/wire with sufficient shielding and appropriate gauge. All but the lowest of low end OEM cables meet these needs. Beyond this, there is zero difference in cables other than packaging and branding. Any perceived difference is in the listeners head.
The interesting thing that I noticed in reading up on the cable was that Pear is local to me.
So I looked up their address listed, and it's residential. From the appearance, this appears to be a virtual company, in a nice Tony neighborhood, and all the owners have to do is sell a hundred cables and the house is paid for.
Oh, and the first and final word on speaker cable is from McIntosh's Rodger Russell.

Not necessarily true. If what they're in contact with isn't also gold, then bimetallism can occur over time, actually creating higher resistances.
Of all audio gear, speaker cables and power cables are probably the ones that have the least effect, if any, on sound quality. I'll grant right off the bat that any difference probably won't be audible. But before everyone gets all comfy in their religous prejudices, consider the history of absolutism - it usually fails in the long run.
We saw it with CD players. 25 years ago it was easy to find hordes and hordes of scientifically-minded folks who proclaimed that CD players were all identical and perfect. They reproduced as high a frequency as the ear could hear. They did so with perfect digital repeatability. They were perfect and identical. That was an unassailable scientific fact. It was even a marketing slogan for Phillips; "Perfect Sound Forever" was their first ad campaign for CDs.
Audiophiles said different. They said they heard differences. When challenged to do double blind, ABX testing, they often failed. They offered up only feeble excuses about how such tests are never structured properly, always being too short and normally using switchboxes that degraded sound. The skeptics and scientists had a field day exposing audiophiles as frauds and hucksters, as (at best) deluded simpletons.
Eventually, though, a funny thing happened. Research got done by audiophiles who were also engineers. They discovered various CD player problems (like jitter) that could be measured and fixed. When those problems were fixed, the audiophiles said the players sounded better. The audiophiles still failed ABX tests and still held to the same excuses, but changes were made, anyway.
Nowadays, anyone who knows what music sounds like (and, yes, that eliminates 98% of the populace right there) can easily tell the difference between a first-gen Sony CDP-101 and a current high-end CD player. There really are differences. Those people who absolutely knew that it was scientifically impossible for any difference to exist turned out to be painfully, embarrassingly wrong. (Nowadays, they tend to fall back on revisionist history: "Oh, we never really said you guys were wrong, just that testing didn't bear you out...etc., etc.")
My point is not to construct an elaborate straw man. My point is that keeping an open mind is a good thing. We have previously seen lots of folks loudly and authoritatively proclaim that a given phenomena does not exist and cannot possibly exist. They cite scientific reasoning (as they spout it) as unquestionable. But that is nothing more than a religous devotion to a position and I reject it.
Sure, the burden of proof is on the people who make claims that cable A sounds better than cable B. I doubt they'll ever succeed. But the vituperative, out-of-hand rejection of alternate views is more than just unseemly; it argues against (indeed, belittles) an inquisitive spirit.
Perhaps some Carl Sagan would be in order. His essay The Dragon in My Garage is right on point. When considering unverifiable and seemingly insane assertions, his advice is that: "...the only sensible approach is tentatively to reject the ... hypothesis, to be open to future physical data, and to wonder what the cause might be that so many apparently sane and sober people share the same strange delusion."
We've seen the mocking, "scientific" approach to audiophile claims turn out to be wrong in the past. We might do well to be a little less sure of ourselves when considering audiophile issues in the future.
Side note: Just to show that there's blame to go all around, note that the offer of the James Randi Educational Foundation folks is, as I have stated elsewhere, disingenuous as all hell. (See Rule 12, a proviso that makes it clear that the offer is only open to whoever they want to make it open to and gives the JREF multiple, too-easy excuses to reject any attempt to claim the reward.) The rules are set up so that the test will never happen. This is little more than a minor publicity stunt that's gotten picked up by too many 'net outlets and given far too much virtual ink, already.
Transistors sound harsher because they don't have as much harmonic distortion.
Both tubes and transistors cause harmonic distortion when saturated. Its the nature of the distortion that causes the harshness.
When a solid state amp is saturated the result is a hard clipped waveform where there is a sharp edge at the point of clipping. This produces a lot of odd harmonics in the frequency spectrum. Odd harmonics over the fundamental tend to sound very harsh to the human ear.
When a tube amp saturates it tends to soft clip the waveform. This means that at the point where clipping occurs the waveform becomes slightly compressed giving a rounder edged waveform. This tends to produces more even harmonic distortion, which to the human ear is not perceived to be nearly as harsh.
