has anyone else tried Lloyd Walkers latest tweak

As I've said before, this whole thing is so unbelievable that I just wanted to see if anyone else heard what I heard.
We can debate theory of operation I was just seeking out others experience

"oral incontinence"... HA :)

Perditty, The only thing I would take issue with is your use of the term "debate". Inert crystals either can or cannot affect RFI. The debate could be about whether they make an improvement in one's audio system; that would be a reasonable subject for debate.

cause of the perceived improvement would be the topic of the debate

I have not tried the Black Crystal tweak, yet.
So, I have no right to form an opinion about it.
Judging from this thread, however, it appears to be 100% effective--based on the accounts from people who, actually, have tried it.
None of the naysayers seem to have tried it. So, their opinions are uninformed, and, in my view, worthless.
A theory is worthless unless experimentation can validate, or, invalidate it.
That is how science works: theory, then, experiment.
I would be interested in reading an account from someone who has tried the Black Crystal tweak and found it not to be effective.
Slogging through the mire of endless speculation this thread contains is tiresome.
