has anyone else tried Lloyd Walkers latest tweak

Benjie and Tawa
thank you for your OBSERVATIONS as this was the reason I started the post in the first place!
Benjie you are so right re the second crystal!!
All of what you noticed when adding the second crystal
[the black diamond turntable upgrade already had a crystal on the headshell bridge, this is replaced by the second black diamond crystal] is what I heard with the second [I CAN'T EXPLAIN HOW IT DOES WHAT IT DOES BUY IT DOES DO IT!!!]
I'm afraid to even mention THIS but Lloyd recently sent me a room tuning kit composed of five copper pipe end caps [like from home depot] with a crystal glued to the inside bottom, they are put on your room walls and/or ceiling with blue tack and you get an expansion of imaging and soundstage that [IMHO] equals/surpasses five speaker surround sound! [I know, I know, pass me more Kool-Aid Jim Jones]

Dear Phduncanson,
Your URL leads to a white paper on RFI. No one doubts that RFI can be a problem in audio reproduction and that eliminating RFI is desirable. If you read the paper yourself you will see that the only way in which crystals are connected to RFI is by the fact that devices that use crystal-referenced oscillators, like the wrist watch specifically mentioned, radiate RFI. The article does not support the contention that crystals shield from RFI.

I am prepared to believe that crystals are beneficial, but I remain to be convinced as to mechanism for that, and that it even has anything to do with RFI.

So, what is it, exactly, a piece off a 1950s Chrysler tail light?

If it's a '57 300C, I want one.

Dear Perditty: It's clear that you are an advocate Walker audio items starting by his TT.

I wonder how much of that biased " expectations " hear helps to listen " things " that maybe exist or maybe not?

Maybe could be good for you to bring to your place a person with out to much knowledge level about audiophile systems and invite him for a half an hour to listen with the cristals inside the system set up, after that take out those cristals and ask him ( with the same LP tracks. ) if he detected a difference for the better or worst or no differences at all.

Many times when we are waiting/prepared to " hear " something then we heard it even that there is nothing.

Our brain is unexpected: please listen to a track that you know in deep with your eyes closed and with your eyes open, after that make the same but with lights on and with lights off and ask you if in all cases you listen exactly the same.

Anyway, at the end of the day the important subject is that you think that you hear improvements and this is what it matters to stay satisfied with and not what other can hear or not.

Regards and enjoy the music,
R.
