Nothing is Too Wonderful to be True

"Nothing is too wonderful to be true, if it be consistent with the laws of nature . . ."—Michael Faraday

"When a true genius appears in the world you may know him by this sign: that all the dunces are in confederacy against him."—Jonathan Swift

I quoted Faraday and Swift in an essay I wrote in March 1991 discussing how to distinguish effective audio tweaks from those that appear to be more about delusion than about any real change in performance. Back then, it was the Tice Clock (a RadioShack digital clock that George Tice claimed to have treated with a proprietary secret process) and the Belt devices (nylon cable ties, metal clips, and other household objects that Peter Belt claimed to have treated with a proprietary secret process) that were disturbing audiophiles' collective equanimity. These past few weeks it has been the "Intelligent Chip" from accessory manufacturer Golden Sound that has audiophiles at each other's figurative throats, to witness the postings on the Audio Asylum. Rather than offer my own explanation of what the GSIC does and why, I'll quote from Golden Sound's website:

"The Intelligent Chip is a 'new generation,' high-tech device that corrects a particular problem inherent in all commercial CD/DVD/SACD discs, including movies and video games. This problem is produced by slight fluctuations in the master clock(s) when pressing the disc. This 'clock fluctuation' problem (jitter) is one reason why consumer digital discs frequently 'don't sound quite right,' or have a 'high-frequency edge.'"

Well, jitter, or time-base error, in optical discs is certainly a real phenomenon. CD transport manufacturer Plextor even offers a suite of programs that, in conjunction with its Premium CD-RW drive, allows you to measure this jitter.

"The Intelligent Chip is a thin, orange 1x1.5 inch rectangular wafer that automatically upgrades the disc in the player when the Chip is placed momentarily on top of the player above the spinning disc. The upgrade itself is virtually instantaneous—and permanent—the sound and picture of the upgraded disc more closely resembling the original master recording. The Intelligent Chip corrects the clock-fluctuation problem within 2 seconds, resulting in sound that is clearer/less distorted, with a deeper soundstage, more 'air' and lower background noise. This improvement is especially apparent on very good discs."

The GSIC10 costs $16 and is claimed to upgrade 10 discs; the GSIC30 costs $40 and upgrades 30 discs. (Let's hope that UPS doesn't carelessly put the package containing a GSIC next to a box of CDs in the brown van.)

Hmm. $1.50 per disc but I get sound that is "especially apparent with good discs." And while the mysterious field emitted by an active GSIC can "virtually instantaneously" affect the physical structure of the spinning disc through the player's metal chassis, it can be blocked by the polyethylene container that contains the GSIC when not in use. Well, in the words of the old sage, I may not know about "clock fluctuation problems," but I do know about bullshit, and the GSIC sounds like bullshit to me.

I can hear the screams from here. How can I even express an opinion about the GSIC when I haven't tried it? How can I willfully dis a product made by a company whose cones and other mechanical devices have long been denizens of Stereophile's "Recommended Components"? Does this outrageous behavior on my part mean that I have a closed mind, that I am [shudder] a closet objectivist, and that pretty soon I'll be forcing not just the magazine's writers but also its readers into endless double-blind testing rituals until, goddammit, all of you admit that everything sounds the same? Even when it doesn't?

No, I'll not be doing that. But if I was tired 14 years ago of tweaks that offended my experience, you can imagine that I am slightly more weary these days. As I wrote in 1991, I haven't so much closed my mind as put up a lightweight semantic curtain at its gate. Things of real worth can still easily push aside that curtain, which I have modestly dubbed "Atkinson's Law of Effective Tweaking." But when the price is high and the explanation is bullshit, why should I waste my precious time?

In a world where the listener's state of mind cannot be eliminated from how he perceives sound—see Jim Austin's "Industry Update" essay on this subject in the March Stereophile (p.24)—"Atkinson's Law of Effective Tweaking" examines the relationship between how much a tweak costs and how much it runs counter to accepted knowledge. (A clue is when the manufacturer claims to have discovered a hitherto unknown form of energy or phenomenon or bandies words about with scant regard to their established meanings. Like "jitter.")

The best tweaks to try are those that seem to have good explanations for how they work and cost nothing. Changing absolute phase, moving your loudspeakers around the room to find the optimum position, cleaning your contacts by unplugging and plugging cables, or determining the correct AC plug polarity, all fall into this category. They can effect an improvement in the sound of your system varying from small to large, and the only cost is your time.

If a tweak sounds unlikely but still costs very little—water-based green ink on the edges of CDs, spiking speaker stands, for example—then why not try it? The price of admission is low enough that even if the effect is small, the sonic return on the financial investment is high. You can enjoy the improvement while reserving judgment on the reasons why.

If the price is high but the explanation offered for any sonic improvement fits in with your worldview, then try it. Your intelligence is not being insulted, and you can still decide that the improvement in sound quality is not worth the number of hours you have to work to earn the money to pay for it.

But when the tweak is both expensive and comes with a ridiculous explanation, file it away in your Pending tray until someone else you trust tries it out. Either the effect will be real and the price will fall as commercial success comes the inventor's way, or the effect will turn out to be as fictitious as the explanation. In which case you haven't wasted your time and energy.

The case of the GSIC reminded me of something similar that erstwhile audio scribe Enid Lumley demonstrated to me at a hi-fi show many years ago. Except it wasn't a magic chip costing $1.50 per use, if I recall correctly, but the plastic tripod out of a pizza box. Enid (who was a very persuasive person) placed the tripod atop a CD player and convinced her audience—including me—that the sound was better. I could never replicate the effect in my own system, but hey, the tweak was free, and that's equally important.

Of much more significance than the GSIC to the high-end audio industry is Apple's Airport Express. Wes Phillips cryptically referred to this inexpensive WiFi hub in his "As We See It" essay in the forthcoming April issue of Stereophile: "When Apple introduced its Airport Express wireless multimedia link," Wes wrote, "it even included a digital port so that an audiophile—such as Stereophile's editor—could network his system, using the AE to feed his Mark Levinson No.30.6 outboard D/A converter. 'Sounds okay,' deadpans JA."

And yes, the AE did sound "okay." I was sufficiently impressed that I wrote a review of the piece for our May issue. I won't give the game away, but I will say that, in combination with iTunes running on a Mac or PC, an Airport Express feeding that high-end D/A processor that you never could decide sounded better than your one-box CD player is the easiest way of piping CD-quality music throughout an audiophile's home.

"CD quality"? Yes, the data appearing on the AE's digital output are identical to the data in the original file. While preparing my review, I compared a WAV music file with a duplicate that I had captured on my PC from the Airport Express's S/PDIF output. I used iTunes on my PowerBook, playing a version of the file encoded with Apple Lossless Compression, to feed data to the AE. Despite the lossless encoding, despite the 128-bit encryption I use in my home network, despite the transmission of the packetized data through the air, and despite the circuit in the AE having to reencode the data as an S/PDIF stream, the files were bit-for-bit identical.

Apple's Airport Express is most definitely not bullshit. And it costs only as much as three Golden Sound "Intelligent Chips."—John Atkinson

If one were using Atkinson's Law, and the cost of the tweak was extremely high, and the explanation smelled of shit, (say, like Valhalla 2 cables) and the people you tend to trust get a little spotty when it comes to tweaks with a terrible cost-to-performance ratio? How does one apply the Law at that point?

Too bad what what so eloquently spewed by Atkinson isn't really applied in Stereophile nor the forums. We get Geoff Kait and May Belt peddling their crank fraud products to no end. Then we have Jason Victor Serinus whom "He is editor of Psychoimmunity and the Healing Process: A Holistic Approach to Immunity & AIDS" ...seriously? How many people has that cured of AIDS? Then he has his whistle therapy business, another looney new age scam. He also thinks EVERY power cable, interconnect, cable lifter, (insert tweak of the month here) has a profound affect on the sound, YET he also thinks DBT isn't something to apply to testing audio products.

Sad to say but also Atkinson doesn't think DBT is a valid way of testing audio products. It's all a circle jerk anyway. If you bring up why cables, wooden blocks and magic bowls aren't tested, you get the "I wouldn't know how to go about testing them" excuse from Atkinson YET he also lets "reviews" of these scam products on the pages of Stereophile and the website. He even goes to the rooms at audio events  and has something  to say about them. Case in point, products from Ted Denney of Synergistic Research. Atkinson never has anything bad to say about these scam products, he just says things similar to "I just shook my head after hearing a difference in the sound after Ted switch in the Tranquility Bases" or " The Acoustic Art bowls made a differnce in the sound". After nearly TWO YEARS of people on the forums trying to get Atkinson to test these "wonderous" bowls, we gave up. He always  had some excuse, YET he had plenty of time to post his own "theories" as how the magic bowls work.

So in conclusion, I say that Atkinson likes to claim to be some sort of "Champion of Science", yes he does post measurements of speakers, amps, DACs and other complicated to measure products YET fails to address even more costly scam products because "I wouldn't know how to go about measuring them" or even better "i don't have the time" (While finding plenty of time to post here and elsewhere on the internet) excuse and lets people like Serinus spew forth his poetic drivel about how "grand" all this shit is.

Your limited reading comprehension lets you down again, JohnnyR. Note that in the essay to which you appended your comment, I wrote that the GSIC was a "bullshit" product.

Comrade JRusskie doesn't realize that no one in the world does proper double blind testing in the way that he wants JA to test all audio products mentioned in Stereophile.

“It is difficult to get a man to understand something, when his salary depends on his not understanding it.” 
- Upton Sinclair, I

Let's be frank here...  JA is in a tough position. He's the editor of this business venture. Companies like Synergistic take out full page ads spouting their wares; and most of what they sell is marketed to those of faith. As much as I think it would be great to see complete transparency and honesty to the point of saying to a major advertiser that their product is "utter bullshit", it's not going to happen. It doesn't happen in politics, it doesn't happen often in the corporate world, it likely doesn't often happen between family members and friends. Such is the politics of maintaining multiple mandates...

I'm glad at least we do have some common sense posted by JA like in this article. And it's thanks to his measurements that I still have a Stereophile subscription. At least there's data for us to assess; unlike most other utter BS audiophile rags out there.

 He kind of just fell off the map. I hope he's doing well.

I dont believe this a CD is made as follows.

Compact disc is constructed of 5 separate layers…

1.   First a thick, soft, clear plastic layer. This layer comprises the majority of the CD's thickness and weight. It serves two purposes. First, it protects the data layer from damage on the play side and Secondly it acts as a lens to focus the CD player's laser onto the data layer so it can more easily read the data (much the way lenses in spectacles help eyes focus on the words on a page).

2.   Next the data layer is where the music and any other information are stored. It's the layer that the CD player "reads" in order to create the music, graphics, etc. The data layer is molded or pressed into the top of the clear plastic layer. The data in the data layer is arranged in tracks that spiral like the grooves on a vinyl record (except CDs are read from the "inside out", the opposite of vinyl records).

3.   Now a reflective, metallic layer is located on top of the data layer. It allows the disc to function like a mirror, reflecting the CD player's laser back to the detector in the CD player after it reads the data layer It's this layer that gives the CD's play side a shiny appearance.

4.   A thin, hard protective layer is an ultra-thin plastic coating that is added to provide some protection for the reflective and data layers, while also forming a surface upon which the label information can be printed.

5.   Finally the label layer is printed on top of the protective layer. It contains the title, graphics, band and other information to identify the contents of the disc. (label side).

I simple dont understand how any device placed near a player can alter any jitter inherent due to clock speeds when the CD was manufactured as the manufacturing is a physical layer and therefore once made cannot be altered.
