has anyone else tried Lloyd Walkers latest tweak

Traditionally, only a few stones don't need clearing(citrine, kyanite, etc.). Unless this crystal is one of those, I would suspect that the stone would need time between listening sessions, in order to clear itself. EMI and RFI, would saturate the crystal, so that it's no longer effective. Is there any drop off in sound quality towards the end of a long listening session?

Alert - possible double post

The really interesting thing about crystals is that they can absorb vibrations of many frequencies - including Very Low frequencies! As when crystals are used in room corners. I suspect focusing on non-audio applications like crystals in radios and watches is a little bit irrelevant to the whole audio applications thing.

Somehow- I couldn't care less! Just enjoy your music!

Hey ya’ll. Allow me to chime in. I’m just another philosophizer about crystals (at least for now)…no empirical evidence here! But have been trying many things in the past years to rid my phono set up of CB radio and faint long wave interference.

A video link to what this malicious interruption was like is on my blog: http://brooklynaudiophile.blogspot.com/

I gave up months ago. Then I explored Walker Audio’s website, talked to Mr. Walker, and bought his Eliminator-T. Thought I would start on the cheap. Problem was just about solved! I can only hear very faint remnants of that highly annoying RFI disturbance and only when the volume is turned up very high (past 2o’clock).

So that has inspired me to believe this Black Crystal may be what it claims… I hope to attain one for my next up grade.

Furthermore, for folks still interested in the connection between crystals and RFI/EMI, for your consideration:

Further furthermore, the Black Diamond seems to be relatively cheap and better looking when compared to these Swedish dudes:

Hello, the article you linked to actually doesn't link absorption of RFI to crystals, it only links emission of RFI to crystals. Sorry about that.
