has anyone else tried Lloyd Walkers latest tweak

I put the post out to see if anyone else WHO HAD ACTUALLY TRIED THE THING heard what I did and it seems one other person has had a similar EXPERIENCE.
As I have repeatedly said skepticism [particularly in this case] is a good thing, but to dismiss, out of hand, with NO experience is nether helpful OR scientific. Again first observe then speculate.

Perditty, I meant no slur. Sorry.

Geoff, There has been a LOT of published science on the behavior of crystals in electronic applications. It's actually quite an interesting history dating back to the 1920s. By WWII, quartz crystals were already being used in the defense industry in electronics, and since the method for growing such crystals in a lab had not yet been developed, natural quartz was highly prized and sought after. There is no occult force in commercial audio that could or would suppress research into this area or any other area of science. You greatly exaggerate the power of the industry, and/or you don't quite understand how basic research comes to be done. I have to think that if free (meaning "not in-circuit") quartz crystals (or any of many other kinds of crystals now available) could absorb RFI, there would be a published paper describing this phenomenon. On the other hand, I agree that my failure to find the papers (so far) is no proof that such work has not been done. I will keep looking. There are EEs lurking here. Perhaps one of them knows.

What works in one system may very well not work in another. Stereo systems benefit from tweeking to eliminate resonances, and correct faults. That's what the joy of this hobby is....enjoy.

I'm generally not one to blow my own horn but I was the first to use crystals in comprehensive ways for audio applications. My crystals debuted at the HI FI Show in London in 2003. As I showed ten years ago Crystals can be applied in many locations, including power cord plugs, RCA jacks of interconnects, near small vacuum tubes, room corners, on top of transformers, on top of speakers, on top of CD players, and many other locations.

Lewm, I have a good feeling you will get to the bottom of this thing. That's exactly what I think we need, more folks that are determined to find out what in the heck is going on with these devilish little crystals. If you find something somewhere out there in cyberspace regarding crystals and their use in audio systems, I mean other than in clocks, please be so kind as to provide a link. You would think NASA, DARPA, IEEE, MIT, AES, ASA - somebody! - would have at least done some sort of preliminary investigation. I would even settle for the Amazing Randi. Lol
