Diamond Stylus Enters the 4th Dimension


So, I went to play a Chet Baker Album last night. Lowered the arm, flipped og the mute switch and.......GARBAGE!

The cantilever looked fine. On examination with my USB microscope I confirmed a sullen fact. The diamond had gone AWOL. There is just a little glue left on the end of the cantilever which is completely undamaged. It is a Clearaudio Charisma cartridge.

Anyone ever have this happen? I played records the day before no problem. I did not take anything to the stylus brush or otherwise. I do use an Audio Technica tonearm lift but it's trigger mechanism is so light. I can't believe that did it and it certainly should not do it. IMHO the cantilever should break before the diamond gets knocked off. 

The cartridge is four months old and I got it from Elusive Disc. It has a two year warranty. Here is where the rubber hits the road.

That could definitely rip your stylus off. (the Onzow)
Daveyf, the ultimate was 3+3's. I could not afford them back when they were available and they did not make very many of them, but you could stack 3's. When you make the speaker 8 feet tall it metamorphs from a lamb into a tiger. The basic characteristics remain just a lot punchier, louder with a larger sound stage. The problem with 2+2's is that they are very selfish. They do not have quite enough horizontal dispersion. If I had the 3+3's I probably would not be lusting after Sound Labs 845's....as much.
Hopefully will hear from Elusive Disc today.
One last note.

Ken Bowers of Musical Surroundings is sending me a new cartridge with a return label for the old one just based on the USB micro pics you can see on my system page. You could not possible ask for a better performance. Kudos to Elusive Disc, Musical Surroundings and Clearaudio. 
@lalitk I do believe the importer is Musical Surroundings. I've never heard of Charisma Audio.
Right. In this case the diamond is glued to the very end of the cantilever. All high performance cartridges use a nude diamond now. Many are pushed into a hole in the cantilever. This is not possible with boron. It is too brittle.
@noromance I'm pretty sure that could not be good for your records. I always keep my lift up when not in play so I can't inadvertently do that. 
Those cantilevers that hang out in the open like that are asking for it for sure. 
jjss49, afraid not, but after the acid I took wears off I should have another look at that cantilever. Maybe the stylus will grow back.
pindac, thanks and what I was thinking, a failure of the adhesive. Do you have any references for that? Clearaudio warns against using any solvents when cleaning the stylus so I have only used a dry brush.
Still no word back from Elusive Disc. Patience is a virtue   🤯
@lalitk do let us know how you like it. It looks like pretty standard construction, boron cantilever, stylus glued to the end just like the one I just lost:) 
Still waiting for a response from Elusive Disc. 
The question for Soundsmith would be are they going to warranty this or charge me for the repair. I'm not sure if they can get a Gyger S stylus. Remember, this is the stylus and cantilever of the Goldfinger. Elusive Disc's exchange charge for this cartridge is $1200. My worry is that they are going to say I damaged it, I just do not know when. My comeback will be then it could not have been a very serious incident and the stylus should have been able to take it. 
Just for yuks I took USB microscope pictures of the cantilever and posted them on on my systems page. I think I know how it failed. There was no glue between the end of the cantilever and the diamond, just the surrounding glue which was very thin on one side. Eventually, it just let go. The diamond should be fully bedded in the glue but there was not any on the cantilever side. They are positioning the diamond against the end of the cantilever then just placing a dab glue on it, The glue does not get into the joint. Any woodworker will tell you this is a bad way to do it!
@teo_audio, do you have specs on the cartridge? How much are you asking. Pictures?
Good news. Sam Arnold from Elusive Disc called to tell me that Ken from Musical Surroundings wanted me to email him the USB Micro pictures of the cantilever and he would send a new cartridge right out! Sh-t Happens.
It is what you do about it that counts.

daveyf, it was 3+3 and 4+4. All of them were 8 feet tall. The Acoustats were worlds tougher than Quads. It is almost impossible to blow an Acoustat. I have personally been party to the destruction of three Quads. This is no comment on current units just the old ones. As for sound quality it depended on how you drove them. Given a powerful class A amp the Acoustat 3's could sound just as good as quads. Once you get to the 8 foot guys it should be no comparison as the sound stage is larger and more detailed than stacked quads which do not form line sources. Again you need a high test amp. We have not even talked about subwoofers yet. My ancient 2+2's with subwoofers will do 110 db all day long. I certainly do not need larger speakers for volume reasons. I rarely go above 95 dB. I would really like better horizontal dispersion which Sound Labs speakers offer. Finding 3+3s is virtually impossible. If I could find good clean panels I could make them but more than likely I will switch over to Sound Labs. 
Yes daveyf your problem was the amp. They did much better with class A SS amps. They also had to be aimed right at you unlike the Maggies. The bass was never that great. You either needed subwoofers or one of the 8 foot versions to get decent bass. I had Monitor 4's mounted on top of RH 
Labs subwoofers. That was a very potent system The 4's were using Acoustat's high voltage tube amp. But I didn't fall in love with the Acoustats until the 2+2's. A full spectrum line source is a thing to behold.
Everything becomes life size and the projection is much better. I went to Apogee Divas for a while. After 6 years out of frustration I returned to the 2+2's were I have stayed for some 20 odd years. Only the tall Sound Labs speakers are of interest to me. I would not mind a little more horizontal dispersion and efficiency. The other advantage of these speakers is no crossover. They are truly full range although IMHO they do much better when you take the bass away from them. The digital cross over I use can be dialed in perfectly. 
This is the advice that is given and I only used a dry brush. However the glue they are using is undoubtedly a cross linking resin of some sort like epoxy which once cured will not dissolve in any common solvent. UV can attack it but that takes decades if not centuries. 
@desktopguy, the new cartridge arrives tomorrow by FedX along with a shipping label for the broken unit. Cost to me = ZERO!
