:soapbox:

The fact that there is so much "snake oil" out there, and that people actually purchase it and think something has changed when they start using it, is demonstrative of how ludicrous all of this really is. Sound is just electronics and physics. Stray away from either of those, and one enters the realm of self-delusion, which is almost entirely the result of being poorly educated in either or both of those fields. This wouldn't be so bad were it not for the seemingly incessant need for most of them to evangelize for useless (or at least overpriced), items of highly questionable value, as though to attempt to justify their shrinking bank accounts as a result of buying it, thereby perpetuating this stupidity.

An "audiophile" and his money are soon parted.

Caveat: This is not the same as actually identifying and fixing a problem, like noise, hum, distortion, etc... But you don't need to take out a second mortgage to do these simple things and unless the gear was poorly installed, or of very low quality, those types of issues won't be present anyway. The people who designed the gear know far more than 99.9% of those who purchase it.

Ropi Jo:
This cannot be snake oil.... surely?

This review of "Brilliant Pebbles" sounds convincing enough...

"By the way, I just placed additional Large BPs in your recommended locations in front and to the outside of each speaker -- these locations created startling three dimensional and solid images and revealed harmonic overtones, providing an even more impressive sense of reality and emotional connection to performers, especially singers. The benefits of these new locations are so much more noticeable and intense as to be quite unbelievable, considering the previous benefits of the Clever Little Clock and the other BPs of various sizes."

I'm quite tempted to pop out to the garden and raid the wife's flower pots and freezer bags and see if I can achieve an emotional connection with my Amstrad.

BadMouth:
Lol.

For anyone who is interested:
Check out Ethan Winer's null tester. He is an audio engineer with decades of experience building studio equipment.

All the null tester does is flip the polarity of one lead and then combine signals.
Everything EXCEPT the difference in the cables is cancelled out.
So if you attach a cheap cable and expensive cable, the output is everything that is different in the signal. ....only there never is a difference anywhere near big enough for a human to hear by any stretch of the imagination.

Thanks for mentioning Ethan Winer's name. I was unaware of him. What a breath of fresh air he is in the vacuum of "audiophile" space. To fully realize how good we have it with audio today as opposed to 40 years ago, you had to have lived and worked with it throughout that time. This man obviously has.

*edit* and he's a pinball fan :lol

Heh, this picture seems appropriate for this thread :)
