and Boron snaps if you fumble the cart off the edge of the platter...Ahh yes runy and Sapphire are crazy fragile, boron is quite strong but ruby and Sapphire almost snaps if you look at it.

If you broke boron you would have broke aluminium or any other stylus type. When cutting boron apart thr cutters getting grooved every cut you feel the force in the cantilever between your fingers. Aluminium cantilever would be bent and crushed with way less force.and Boron snaps if you fumble the cart off the edge of the platter...
Ages ago I tried to break aboron cantilever between my fingers ( tip was missing and it was damaged anyway) just for curiosity. It broke of course but it took quite a lot of force.You might get a bounce or 2 out of boron.
^^ good luck finding one
Why did you go Shibata?The Reference Platinum is on its way back from Joseph all repaired now with a Nude Nagaoka Shibata on hardened tapered thin wall aluminum / magnesium cantilever.

I’m sure it’ll sound great - but you’ll need to let us know how much better it is with the Shibata than with the original tip..!
Still listening to the Reference Platinum 1 with the jarrah body and it’s still sounding very good. No idea how many hours are on it (bought used) but since it sounds good and tracks well, I’ll use it for a while longer, I think. Then I too, have to send a couple in for new tips.
I went with the Shibata in hopes it will be a step up from my MC carts not its previous stone, if not then money wasted on a cartridge that won't see any use.
I think the new tip will have it sounding surprisingly nice; probably as good as Grado’s more expensive cartridges!![]()
On most arms, including RB-330, I have to set up Opus3 at 1.75, but on Acos Lustre GST1 1.5 g is enough. There is something about these old tonearms (sometimes).
It was OK at 1.6, mostly, but inner track sibilants made me push it higher. It is perfectly safe to go up to 2 g with that stylus.Mine is mounted to an RB-330. So for you 1.6 wasn't enough? I'm going to try and play something heavily modulated and see how it sounds.
Thought I'd add a quick question here... what are you Opus 3 owners tracking at? I initially set mine to 1.9 grams, but yesterday I reduced it to 1.6 with no loss of tracking ability.
I have the VTA set slightly tail down (stock rega arm with no spacers - the Grado instruction sheet says use either a parallel arm or up to minus 2 degrees)
The sound is wonderful.


Since we're sharing photos here's mine on the RB330/Planar 6. Alignment was via the Rega protractor included with the turntable. You've got some cool gear!Mine is very happy tracking at 1.8g and with armtube level. It sounds excellent here. Been keeping the playtime off of it though and using a Reference Platinum 1 on an RB250 arm. That one sounds quite nice as well..
