has anyone else tried Lloyd Walkers latest tweak

Yet another high end manufacturer jumps on the crystal bandwagon. I thought crystals went mainstream about five years ago.

How much does the "crystal" cost, and by what means is it secured to the arm or cartridge?

I am sure that the crystal cost is commensurate with it's sound altering ability. There simply cannot be a crystal that uniformly fits every system and room. Prices may end up tiered I haven't looked I am still trying to assemble the glory of my old set up, which may require a more potent tweak than a crystal I am thinking acoustical geode but they would be ultra high end.

Don't laugh guys. LLoyd Walker is the real thing. Probably no snake oil here, just unconventional thinking that works. No, I haven't heard the thing and I bet it isn't cheap, but I'd be surprised if it didn't change the sound, and probably for the better. Once I wanted to add some weight to my tracking force without messing up the settings. Takes too long to get it back just right. So, I a placed a stainless steel nut on the cart with a speck of tape. Just like we had a quarter on the family's old Zenith console's arm as a kid. I found that the nut improved the sound even when tracking force was compensated for it. Probably if you put your Wife's diamond on the cart the sound would really improve!

The crystal is $325
The improvement priceless!
It is glued to either the headshell or cart body ( visit Walker audio web site for more info )
