Tomorrow - hands are shaky - cold from being outside. I spent most of my life 70lbs heavier than I am now. That's a lot of missing insulation!

And you stumbled on the second part of why I don't want to play with styli right now - while the puppies were outside playing, the dads had a couple beverages.

Do you have any experience with the carbon fibre rod used by Zyx? It is interesting because it is a fabrication, unlike other cantilevers in that it is not just a material (with the inherent properties of that material) fashioned into a shape. Technically that would give them more control over getting the properties they want.
cheers
Circa 7mm to pivot point - which is pretty standard for most styli...
I was thinking to show the boron rod part of the JICO, around 3.8 mm. If the boron part of the MP-500 is 2.75 mm as JP mentioned above, the HF resonance should be higher.
My VN5MR HG SAS/B is about bang-on 3mm.
Yours is a V or Vx?
Vx. I always wondered about the differences 10-20 kHz I got with different Vx SAS B stylii.
Fun with vinyl measurements
Did you do anything to load the cartridge? The V15 has a bit of inductance; in parallel with the capacitance of the tonearm cable and the input capacitance of your phono section (not specified; it always should be in measurements like this). That results in a resonance that will behave like a...

I have not checked stylus length of my previous though. Need a good loupe with scale to get more precise measurements.

Mine is a VX as well and I need to buy a new Jico for it. I noticed there aren’t measurements for the ruby or sapphire Jico. Are there any advantages?
I thought about buying the Ruby mostly to measure but I wasn’t in any rush. I kinda am worried that in the next year prices to import might go up so I’m in a bigger rush to order soon than I was. The value of the ruby probably isn’t very good relative to the boron but there should be some difference right?

Don’t bother IMO. They are more expensive but not better. I bought one once but it had problems and did not fit the body. In the end it broke while trying to fit it.

IIRC I've a Vx body in a pile waiting to be shipped to me, so I may pick up a SAS/B for it.

Well good. You’ve saved me some good money. The main complain I’ve heard is fragility and Quality control. I’ve not seen any measurements showing the benefit, just the typical people claiming it sounds better.
I was thinking the opposite might be true, as the mass per distance of the "socket" tube would be higher than the mass/distance of the boron rod - hence the longer the rod is, and the shorter the tube is, the more likely to get a lower net effective mass... and the higher the res f
It is complicated. The effective mass as well as the compliance of the structures combine. If someone can calculate the resonant modes of a 0.28 mm diameter boron rod of different length?
Crucial is how long the cantilever is in total. What about the OM cantilevers?

Always difficult to get readings - I found a post by Luckydog who measured the OM stylus to 4.05 mm from tip to pivot. I have not checked mine yet but looked at the AT stylus I had, which is ≈ 5-6 mm from tip to pivot (or even longer - not sure how far from the dual magnets the pivot point is).
I have not heard anything from Luckydog in quite a few years - where is he hiding?
I really don't know. I hope he is ok.
I think the last place he was active was diyAudio, or at least that was the last place I saw him posting. Funny - I was reading a lot of his posts on VE researching the supposed "JICO criteria" for assessing stylus wear just a few days ago. More than a dozen years later and most people still can't see the obvious folly in that.
I'll try to reach out to him on diyAudio. I've been meaning to as it'd be amazing to get his old spreadsheet tools/calculators. Very doubtful we'll see anyone else put that much work in to understanding how this stuff works and poking at sacred cows - would love to know that body of work isn't going to get lost to time.
