Audio absurdities Options

[thesurfingalien]

Hi All,

I have been active in the (high end) audio world for about 25 years. My main interest has always been loudspeakers and design. As such, together with a friend of mine, we have created some pretty decent loudspeakers. We did this just for fun.

Contrary of what you might expect, I have not invested in expensive equipment myself, mainly because there is only so much money I am willing (or able for that matter) to spend on it , and I like to listen to the music and not to the equipment.

However, during this time I have run into what I would like to call "Audio Absurdities". By that I mean things that people do (usually this involves spending a lot of money) to make their setup sound better.

One thing you should know of me is that over the years I have become a very skeptical person with regards to audio. But that does not mean I have lost my sense of humor. Hence this tread...

I would like to invite you to post your experience with this type of things. Be it for either generate a good laugh, or warn other readers for costly "audio improvements" that can be categorized being scams.

Have fun or be warned :-)



My first contribution: The Magic Woodblocks

About four years ago I heard from a to remain unnamed person that he had obtained little pieces of wood, about 2" square, varying in thickness depending on application, that should be placed under the equipment's feet. According to the vendor, the wood was from a rare species of trees only to be found in the Amazon. The audible results were claimed to be like "upgrading your equipment to a model twice the price". And that for only US$250 to US$375 per set of three...

CD rings/guards which were thin round rings either rubber or flexible plastic that went on the outside edge of a CD (personally I'd just call them CD rubbers) were in some audio-type magazines back in the 1990s.

They were marketed as "protecting and stabilizing to increase audio quality" for audio CDs during playback since they supposedly raised CDs an insignificant amount off the CD tray. But in reality they caused more problems, could get slightly baked onto the CD leaving residue behind on the outer ring of the disc, and if they broke off whilst inside a CD player it could become damaged.

That's quite amusing considering the CDs don't sit on the tray during playback anyways

On some Pioneer models, it would. The disc would be upside-down on a turning platter, meaning that you could not use those plastic disc clamps.

I actually heard a «disc clamp» kind of thing that made an audible difference. I mean, a «WTF?» level of difference. Never had the chance to check out the details, but I suspect there was some resonance rattling off in the player itself. (Hm ... if I had such a CD ring, I'd try the trick on my early DVD-player ...)

I can not remember when, but at some time one could buy a black CD marker that one should apply to the outer edge of a CD, coloring it black, claiming improvement on sound. I can not recall the specifics, but it had something to do with canceling reflections.

I believe it was an audiophile magazine that analyzed the markers, and found out they were nothing more than regular permanent markers (the Edding brand if I recall correctly), sold at about 25 times the price of the original.

Obvious fraud. The ones that did deliver the sonic bliss, were the green ones.

I didn't realise that. Wouldn't you just have a continuous scraping sound as the disc rotated on the surface it was sitting on though? Plus all that friction wouldn't be good would it?

No: Put the disc upside down on a «turntable» platter. The platter rotates.
