A minor rant

Prologue: this is a minor rant. It will not be tediously long, and it will not attack anyone. Proceed only if interested in reading a short diatribe on reviews about tweaks.

Almost all serious members of our hobby have tried various tweaks over the years – some successful, some not. Infact, tweaks are so much a part of our hobby that dedicated audio enthusiasts are often referred to as “tweaks”. I’ve tried a lot of tweaks myself over the years, and most proved of dubious value, but most were also fairly cheap. Many of us indulge in tweaks in the hope they will get us closer to audio nirvana. I think, however, that the variety and price of tweaks has reached the stage (like interconnects) that, as Monty Python might say, they are “silly” (envision John Cleese doing his bit as the Minister of Silly Walks…).

During lunch today, I strolled down to the Tower Records in the University District (a block or so from the Univ of Washington campus) to browse for a few CD’s, and wound up buying the current issues of “Listener” mag and “Audio Musings” mag. The copy of “Listener” contains a subscription ad with a picture of a coiled pile of feces sitting next to a can of Shinola wax, with the caption: "Read ‘Listener’, and learn the difference”. Did this ad inadvertently contain an editorial statement about the very tweaks that were the subject of their review article?

There are two tweak products reviewed in the mags: the Rollerblock Symposiums (which sell for $300 for a set of 3 steel balls, with their blocks – and for only $75 more, with tungsten carbide balls) (I once knew an Army drill sergeant with a pair of those, but that’s another story…), and the Aurios “Media Isolation Bearings” (MIB’s), which sell for the same price.

“Audio Musings” has an equipment review of the Aurios bearings, which the reviewer tested under a Parasound 1500 power amp (also the subject of a full review). To determine how effective the isolation bearings are, the reviewer placed not one set, nor two sets, not even three sets under the amp. He eventually placed 5 SETS OF BEARINGS (3 bearings per set) under the amp. That’s $1500 worth of isolation bearings under a $995 power amp!! Here’s a quote from the Audio Musings review:

“I switched amps to the Parasound 1500. After getting used to its sound, I placed three Aurios under it. With just the three Aurios MIB’s, there was a slight but noticeable improvement. With each addition, the level of improvement was noticeable. Then I put 6, 9, 12, and then 15 MIB’s under the amp. With each addition the level of improvement was noticeable. Boy, was I surprised. This raised the level of performance to quite a degree…”

Let’s set aside the issue of whether the reviewer suffered from “audio delusions” working as a possible factor here. Does anyone in their right mind actually spend 50% more than the cost of the amp (or other component) on isolation tweaks? What kind of improvement would be realized by getting a $2500 amp with regular feet, vs. a $1000 amp with $1500 feet? At what point does improvement from adding more MIB’s reach a plateau? Could an actual human being hear the difference between 15 MIB’s vs. 30? Or 45, etc. If these isolation bearings offer such "noticeable improvements", why has no component manufacturer seen fit to make them standard on their products at a fraction of the $300 cost (for one set)? (Would you buy a $20,000 car with $30,000 tires?)

This kind of asinine reviewing is what contributes to “normal” people seeing audiophiles as strange at best, and maybe clowns or dupes at worst. This review really aggravated me, and I appreciate having a place to vent to my fellow ‘philes. Thank you – I now return control of your computer to you.

Coupling? Decoupling? Tweaking? This is beginning to sound less like an audio discussion and more like a Ron Jeremy Film :)

But seriously folks, in my experience decoupling, i.e. ball bearing, cones, tiptoes, etc. etc., Works better when high frequency vibrations are troublesome, such as with a CD transport. On the other hand, coupling works best on amps and turntables. I heard of a guy that went so far as to get a 12" thick hunk of tombstone granite under his turntable! HA!

well actually there are some tires in our base billing guide that cost me $45,000ea.!!!!They are big ass goodyears used on those earth haulers, they are roughly the size of your house and like 90ply tread with a mere 80 ply sidewall. Personally I run Nokian NRV's(225/55-ZR16) on my car by no means 30k but also worth mentioning, then again I suppose my rig was more then 20k so I suppose I am dumb to waste that much on a car and put 'cheap' tires on it. Oh by the way most all big plane tires are the same and not too expensive, in relation to the price of the plane that is, there is an airport down the road from my shop and every now and again we do a whole lotta tires for them, they go by how many landings rather then mileage(good idea)so after so many landings they have to replace the tires(rednecks like using them on there trailers/wagons for runnin through the woods). That is enough tires for an audio web page. Over and out.

Reading audio magazines is like reading Playboy, Motor Trend, or The Wine Spectator. The whole point of the magazines is to keep people dreaming of that one complete system they could die for. You know, the one with the big tubes. Most of the magazines are full of subjective, goofy, adjectives that do little of inform the reader of how any particular component is designed to function in the real physical world and whether it lives up to these designs. The only numbers they publish are prices. Go to a shop and listen to something new. Take an extra shift and work a little more so you can save up for something better, or at least get a book and learn something rather than sitting around reading this mind candy. One magazine I have found that actually does contain some interesting material is Audioxpress. Though they may be too technical sometimes, you will not be pummelled to death with syrupy adjectives.
