Boron Cantilever and Ruby Cantilever, Why Ruby?

Mechans:

Diamond and sapphire are extremely brittle, in that you cannot bend or flex them without breakage. I did not mean they were not strong materials.

In a long needle shaped (ie length>>>diameter) structure like a cantalever, they would be very fragile. As used in jewelry in bulk crystal form, of course not.

In a cantalever, they are probably attached to an elastomer of some sort to allow flexing and movement. This allows some degree of freedom but I still suggest that these must be handled with the utmost care.

Elizabeth, could you comment on the differences between the Karat 23 and the 17D3?

I have the 23RS so am familiar with that - just curious about the difference with the latest 17D3...

I believe the 17 refers to a 1.7mm cantilever where the 23 refers to a 2.3mm cantilever ?
So there is more than one difference - material (ruby vs diamond) and cantilever length.

Heck even basic aluminium cantilever at 1.7mm would provide magic I would have thought!

Original question does not appear to have been answered?

While any cantilever should be treated with care, my experience is that sapphire/ruby are not particularly fragile.
My Talisman Sapphire survived many years of heavy use without needing to exercise 'utmost' care (its still in one piece). I've been using my Denon 103R with a modded Soundsmith ruby cantilever for about 18 months - and that 'feels' quite robust too.
On the other hand I've managed to snap a few boron cantilevers over the years.
Although this is not solid data, I suspect boron cantilevers are more 'fragile' than ruby/sapphire.
I think aluminium cantilevers are quite fragile too - they won't 'snap', but they will bend, after which they're ruined. YMMV.

Hey tobes, - - - are you out there?

you’ve answered a lagitiment question pertaining to this post, "is going through the repairing process," benificial? Pointing out a cavet’  that has to be pending, and you say "my experience is that sapphire/ruby are not particularly fragile". " I’ve been using my Denon 103R with a modded Soundsmith ruby cantilever for about 18 months - and that ’feels’ quite robust too".
Spot on man.
So now knowing that the Jem Cantilever repair isn’t impractially delicate, IS a load off, but you only answered part of your experience (how’s the sound)?#1: Is the Soundsmith ruby cantilever a sonic improvement over the factory stock Denon 103 cantilever?#2: Through your experience, do you recomend the Soundsmith route, or, if you had to do it again would you go with the factory exchange program?#3: Your make on: Sapphire cantilever vs Soundsmith ruby cantilever?
Thx,appreciate it.
