has anyone else tried Lloyd Walkers latest tweak

Lloyd Walker has a new tweak: the black diamond crystal for cartridges. It's a crystal you put on either the tonearm or the cartridge that [I KID YOU NOT] transforms the sound!
I know, I know, [don't ask me to explain it,I can't] it can't be all that, but i'm tellin you try this thing [if you don't like it you can return it] for less than half the price of a really good cartridge you get A REALLY GOOD CARTRIDGE!!!
Please post your experience

Raul, the Ultra version of the clock is the evolution of the original Clever Little Clock that came out around 9 years ago. The Ultra clock, unlike its predecessors, includes an anti-static spray that is applied to the surface on which the clock sits. To eliminate the effects of the clock take the clock outside, say on the back steps. It all depends on the system but most customers are easily able to hear the clock's effects when placed anywhere in the room. Also, please note the time displayed by the clock is set up to be later than your local time and should not be re-set. The clock is based on theories and products of PWB Electronics who used to have a clock a long time ago and who gave me permission to make the Clever Little Clock. The theory if how the clock operates involves "information fields" and how they can degrade our sense of hearing.

I agree $400 is not a drop in the ocean but you will be hard pressed the find a greater improvement for the price or five times more, [the improvement is that dramatic]
I hope you get a chance to hear it for yourself.
Dear Benjie: Maybe a misunderstood by your part or a bad explanation from me because I'm not saying that the Walker cristals are a true snake oil because I have no first hand experiences to attest it and no I'm not against it but only trying to understand it.

Btw, the track you mentioned has not really deep bass, I think that the bass comes from a digital drum and in the track we can hear its " on porpose " precense. I think that what we hear there is more a low mid bass in the 335hz-45hz.

Now, I don't like those vibrations that you heard and hear with the cristals, I like more when you say: with out it there is no vibrations on windows. Please let me explain ( and of course that I can be wrong. ):

today my system has a very good bass management and thanks to two powered subwoofers goes really down but with one important characteristic: low low distortions down there and elsewhere the audio system performance. Years ago my windows vibrated and I was really proud because of that till I learned that those bass vibrations came from high bass distortions and not because bass music information.

Well, I just listened that J.Warnes track at 100 db SPL at my seat position with no single window vibration then I change the subs volume ( higher. ) and things gone more or less the same.

It's obvious that I can't say for sure but seems to me that if your windows vibrate with the cristals that's is not a good thing because could be only higher distortions and no true music improved information.

Perditty posted that he think bass goes deeper ( you listen the same. ) and my answer to him was that it can't go deeper because the stylus/cantilever pick up from the grooves depends only on the stylus/cantilever tracking abilities where cristals or anythinhg else can't help but in the other side if the cristals makes a clean up to the stylus/cantilever information then we can have a lower noise/distortions and clkearer and better music definition with wider dynamic range and music power and maybe this is what is happening but not deeper bass.

The other subject is if what we can hear through the cristals put us nearer to the recording nearer to a live music and I have no way to know it till I hear it.

I was unaware of these cristal tweak till now. I read it on TAS JV Walker TT review that in the latest version the TT comes with those cristals everywhere: headshell, underside the platter, the air bearing, the motor and in the motor controller too. I did not importance to that fact because seems to me was a Walker TT unique and not for any of us as now is in the market.

Regards and enjoy the music,
Dear Perditty: As with the clock by Machina Dynamica I don't think that the cristal owners or reviewers were " deaf " and certainly ( with all repect ) no one of you are " crazy " and ceratinly listen what you say are listening.

I think that as with the MD clock I have to pull the triger with this cristals to attest or not if put me nearer to the recording/live music. We will see.

Anyway, thank's to brought here this Walker " snake oil " :)

Regards and enjoy the music,
