What’s your vote for the most ridiculous, overpriced, and useless tweak?

Kimber Cable. Not a big fan. No arrows. Nevertheless...

mahgister, my Brilliant Pebbles, the world’s first comprehensive crystal based tweak, was officially introduced at the HiFi Show in London in 2003. Currently Brilliant Pebbles employs various pure crystals including - but not limited to - agate, quartz, sapphire, ruby, aquamarine and onyx. Power to the Pebble! 🤗

I know that Geoff, I read your site years ago (and some others sites about crystals use but your price were right and not over the roof) and decide to experiment myself a bit beyond ( I dont have money to buy gear or tweaks)...For example a cabled connected, battery powered stones grid + magnets...After that I read about your comment about Helmhotlz resonator, I go with my own simple cheaper design after with bottles,carafe, plastic and glass containers in my already treated room with great results etc...


I know that you know about Schumann generator, but not about Shungite connected antenna... By the way it is important to controls vibrations with the generator I am sure you know that...But Acoustic Revive and other companies that sold generators sold them with linear power supply, that are costlier in general...It is possible to use an ordinary cheap power supply and treat it against vibrations but also clean some of the noise with specific crystals and stones... This is one of the main reason that my cheap generators are very efficient and compare probably to the costly one with results that are audible and spectacular for me... The power supply is very important then must be treated...The S.G. must also be  treated against vibrations...

I am not a physicist like you but certainly a maverick for the common eye of the crowds, like you...My best...

Another important thing:

The Schumann generator act like a measure apparatus, a magnifying glass, for the ears because it magnifies the particular effect of each stones or crystals in an audio system at a more evident and audible level than when the stones are only used in a grid connected or not...

You see I am more nuts than you for most of the people...Nevermind! Crowd lack imagination...

It has been reported many times that isolating the Acoustic Revive Schumann frequency generator from vibration improves performance. Also using a better power cord. The performance in audio applications appears to be related to how accurately the 7.83 Hz is generated. That’s why I decided to get the Black Schumann USB device which, at twice the price of the Blue, generates a more accurate signal.

Since crystals generally act as resonance control devices it’s possible they improve the generation of the 7.83 Hz signal. In a similar fashion crystals on top of Tube Traps improve their performance. Or crystals on a power cord plug improves audio performance.
