Who needs a Diamond Cantilever...? šŸ’


So suddenly, there seems to be a trend for Uber-LOMC cartridges released with Diamond Cantilevers...šŸ˜±
As if the High-End MC cartridges were not already overpriced....?!
Orofon have released the MC-ANNA-DIAMOND after previously releasing the Limited Edition MC-CENTURY...also with Diamond Cantilever.
Then thereā€™s the KOETSU BLOODSTONE PLATINUM and DYNAVECTOR KARAT 17D2 and ZYX ULTIMATE DIAMOND and probably several more.

But way back in 1980....Sony released a Diamond-Cantilevered version of its fine XL-88 LOMC Cartridge.
Imaginatively....they named this model the XL-88D and, because it was the most expensive phono cartridge in the world (costing 7500DM which was more expensive than a Volkswagen at the time)....Sony, cleverly disguised this rare beast to look EXACTLY like its ā€™cheapā€™ brother with its complex hybrid cantilever of "special light metal held by a carbon-fibre pipe both being held again by a rigid aluminium pipe".
The DIAMOND CANTILEVER on the 88D however......was a thing of BEAUTY and technological achievement, being formed from ONE PIECE OF DIAMOND including the stylus šŸ¤ÆšŸ™šŸ½

Iā€™ve owned the XL-88 for many years and recently discovered that it was my best (and favourite) cartridge when mounted in the heavy Fidelity Research S-3 Headshell on the SAEC WE-8000/ST 12" Tonearm around my VICTOR TT-101 TURNTABLE.
Without knowing this in advance.....I would not have been prepared to bid the extraordinary prices (at a Japanese Auction Site) that these rare cartridges keep commanding.
To find one in such STUNNING CONDITION with virtually no visible wear was beyond my expectations šŸ˜ƒ

So how does it sound.....?
Is there a difference to the standard XL-88?
Is the Diamond Cantilever worth the huge price differential?
Is the Pope a Catholic....?

This cartridge simply ā€™blows my mindā€™...which is hard to do when Iā€™ve had over 80 cartridges on 10 different arms mounted on two different turntables šŸ¤Æ
As Syntax said on another Thread:-
When you have 2 identical carts, one regular cantilever and the other one with diamond cantilever (Koetsu Stones for example), the one with diamond cantilever shows more details, is a bit sharper in focus and the soundstage is a bit deeper and wider. They can sound a bit more detailed overall with improved dynamics
Iā€™ll leave it at that for the time being. I will soon upload to YouTube, the sound comparisons between the two Sony versions on my HEAR MY CARTRIDGES THREAD.

But now Iā€™ve bought myself a nightmarish scenario.......
There is no replacement stylus for this cartridge!
There is no replacement cantilever for this cartridge!
Each time I play records with it, I am ā€™killingā€™ it a bit more šŸ„“šŸ˜„
If I knew how long I had left to live......I could program my ā€™listening sessionsā€™ šŸ¤Ŗ
But failing this.....I canā€™t help but feel slightly uncomfortable listening to this amazing machine.

Chakster,

I am only trying to address your statement that i loosely interpret as 'they do not mount diamonds like they used to'.Ā  Here are the pictures of your historical examples along side current offerings from Namiki and I do not see any appreciable difference.Ā  Can you explain how they differ?

You will get no argument from me about materials that are no longer available as being 'better' or that Fritz Gyger offers options with just an adhesion bond (as does Namiki with their Microridge).Ā  I also understand the uniqueness of the XL88. I just take issue with the thought that the heyday of the diamond cantilever junction is long past.

There is no image on your link, Dave. Maybe you can re-attach it. I have modern cartridges with Boron Rod (Phasemation for example) and I took some nice picture using my macro lens, so I know the method.

Some of my favorite MC cartridges are low compliance with aluminum cantilever (FR-7f, FR-7fz, Miyabi Standard, Miyabi MCA ... just to name a few).

But my favorite MM are often with Beryllium Pipe or Boron Pipe and I believe this is critical for high frequency extention to have a low moving mass and high compliance. Pipe is always lighter than Rod so the moving mass is lighter with Boron Pipe (or Beryllium pipe). Audio-Technica made gold-plated pipes, after Beryllium was restricted they could only continue with Boron Pipe, but not anymore!Ā 
Interesting discussion as always, Halcro. Re the ā€œprotuberanceā€:

It appears to me that the protuberance is intended to keep the cantilever from moving too far in the downward direction. Perhaps to avoid putting excessive stress on the suspension (?); particularly if the cartridge were set up with aggressive positive VTA or accidental dropping of the tonearm.

Beautiful looking (little) beast!
Thanks Frogman,
Always a pleasure to see your participation and comments šŸ˜ƒ
And I think you've nailed the 'protuberance'....šŸ‘
Makes sense knowing the brittleness and expense of diamond as a cantilever material.
I wonder if the new modern LOMC cartridges with diamond cantilevers have something similar to limit deflection?

Not to go too far off topic but why isn't boron tubing still available?Ā  Obviously Namiki can deal with zirconia tube so the boron tube if available shouldn't be a stretch today.Ā  A few years back when one of the two boron rod manufactures in Japan closed its doors overnight there was a worldwide shortage of boron cantilevers.Ā  Jico turned to sapphire for their SAS and Namiki was willing to try different materials.Ā  Boron rod eventually came back on the scene and is my current favorite.
