Jico SAS vs Neo-SAS(S) vs Neo-SAS(R)


For those analogue ‘tragics’ comfortable enough in their own skins to keep playing MM cartridges despite the media and peer-pressure propaganda towards MCs…….the success of Jico and their after-market replacement styli has been good news.

Of particular delight to that minority still playing vintage MM cartridges……the success of the SAS stylus from Jico.….. has transformed cartridges like the Shure V15, Victor X1 and Z1 and Garrott P77 into world-beaters amongst the cartridge elite.

 

What is so special about the SAS stylus?

It seems that Jico has invented a profile more radical that the standard ‘Line-Contact’, VdH or Shibata…..

An inspection of the diamond under a 60x loupe displays cutting-edge profiles I have never before seen on a stylus.

Jico claims that this profile better fits the record groove and is more akin to the profile of the cutting-lathe stylus.

The better the stylus fits into the record groove, the less distortion is caused by high-amplitude reproduction

But claims are pretty meaningless in the analogue world unless they are backed up……

And with the SAS stylus, the performance matches the ‘hype’….

In all three cartridges I have used….original 35 year Garrott P77, Shure V15/III and Victor Z1….the SAS has transformed each one, from a very good performer to a superlative one.

The improvement over the original manufacturer’s stylus is muti-faceted…

From frequency response (bass and treble in particular) to transparency to sound-stage (both width and depth) but most importantly……to the emotional content able to be extracted from the vinyl grooves.

My three SAS-equipped MM cartridges leapt into contention as ‘the best’ of the 80 or so cartridges I have owned and bettered all but 3 or 4 of the 20 LOMC cartridges I have owned……

 

So imagine the reaction when Jico announced 2 years ago that production of the SAS stylus was being suspended……?

The original SAS stylus came with a boron cantilever and there appears to be a problem with the world’s supply (or price) of boron….?

Now I have a preference for beryllium as a cantilever material but because of safety standards surrounding the toxicity of beryllium during the manufacturing process……it is no longer offered as a cantilever material.

Why they can still use it for dome tweeters is a mystery to me….?

Boron is used as a cantilever material by many cartridge manufacturers…..Dynavector, ZYX, Lyra to name but a few….so why Jico is no longer supplying it is puzzling.

Six months ago, Jico announced the re-introduction of the SAS stylus but this time with a choice of sapphire or tapered-ruby cantilever….both at massive price hikes to the boron.

The tapered-ruby is almost 4 times the cost of the original boron cantilever…..


A comparison of the three SAS assemblies is revealing……

With the original boron cantilever, the actual stylus is buried under an epoxy glue sarcophagus in a manner that can only be described as rather crude….

Just the tip of the faceted diamond is visible poking out of the epoxy…

The new synthetic jewel cantilevers are different animals entirely.

The sapphire appears translucent (not blue) with the nude stylus expertly and neatly cut into the jewelled rod whilst the ruby is even more impressive, again having a nude diamond cut into the ruby rod which has been ‘shaved’ down 2 or 3 sides to create the ‘taper’. And this rod glows ‘pink’…..justifying its premium pricing ?

 

I picked the Garrott P77 for this test because the neo-SAS(R) was not yet available for the Z1 and the V15/III, though wonderful…..was not quite up to the standards of the other two……

 

When I received the two new SAS styli, I was in two minds about them…..

Could the simple change in cantilever material make a noticeable difference in performance?........and for the price increases, it had better!!

There is little doubt in my mind that the SAS’s performance boost was due primarily to the radical stylus shape and as noted earlier…..boron is a respectable cantilever material utilised by high-performance exotic MC cartridges the world over.

If sapphire or ruby were to offer even increased performance benefits over the boron…..then why wouldn’t other manufacturers have already changed over?

These thoughts mingled with the aesthetic appreciation of the ‘nude’ mounting and the ‘glowing’ jewelled rods as I swapped out my original SAS and went straight to the neo-SAS(R)….

 

If I was expecting a revelation…..I was disappointed.

In fact, if I was expecting a difference …..I was disappointed.

No matter how many albums I played (and each album side I would change styli)….I could discern no differences.

And I really tried to hear differences….

At one point I thought I had picked the only audible difference as being slightly better bass response with the two jewelled cantilevers….

This was revealed by albums from Massive Attack and Dead Can Dance.

So I brought in the decider for bass reproduction…..the Barber ‘Adagio for Strings’ on Gary Karr’s ‘En Aranjuez con tu Amor’ (Firebird) sends even my Vandersteen 2Wq subwoofers into fibrillation mode…..

But no……seemingly equal bass response…..

 

So there you have it…..

For two weeks I have exhausted my test-record catalogue, loosened the stylus-plug-insert on my Garrott P77, annoyed my wife and angered the neighbours….

And I can report that I am able to discern no differences….absolutely none….between the original SAS the neo-SAS(S) and the neo-SAS(R).

I’m sure that there will be those who will claim they can hear differences and the differences are like ‘night and day’…..

Good luck to them.

Maybe they can….maybe they can’t.

At least I will have no need to buy replacement neo-SAS styli for my Z1 and V15/III.

 

The good thing to take away from this exercise is this:-

The neo-SAS stylus assembly from Jico is just as good as the original SAS and for that…..the analogue world should be eternally grateful….

I think they had shotguns and a mean attitude. They told everyone else to leave.

But no, this was just a general drift into boron as the cantilever of choice for extremes of ’best’. I was paying attention and watching it evolve. Information as to the why of boron over sapphire was not generally spoken of unless the writer or manufacturer was into the whole fidelity thing and trying to push for boron. Very little data was around but it was of a pretty decent consensus.

Professionalism tends to disallow for trashing of others in public so the advantages of boron were spoken of but the deficiencies of sapphire were not generally spoken of unless the given supplier of carts was pushing some boron on the public (vs a strong competitor or their own older sapphire equipped units, etc). Then they waxed poetic with the technicalities of the situation. One might have read on the subject sporadically for years during that time period, but found the relevant data in a total of, what...maybe 5-6 critical sentences -spread out across only a few articles. Hard to come by lore that is hard won, is not given away, unless one is a fool, or independent of the given scenario but somehow possesses the relevant information.

The big cart companies of the time...could afford to bring that (boron) down into lower priced ’mid-high’ cartridges. Volume provides cost advantages. etc.

Then the mass manufacturing advantages began to fade, costs went up... digital came slowly creeping in..and it all slowly went silent and senile in the wide swath of the middle range of the given gear available. So boron went away except at the extreme high end of things. And fewer suppliers, one would guess, with higher prices.

If one has to take their entire mid-high line up... and abandon boron and go backward into aluminum cantilevers, there’s no way they are going to even make a peep about that...so the market reduction from quantity and quality as a pairing, down turned into something less...happened in utter silence. Marketing and public perception made it necessary to have it play out that way.

Just like it did with Delta-sigma 1-bit dacs vs the superior R2R/Ladder dacs in all the digital gear.
I will add my 50 cents... I don’t think any cartridge with Boron Cantilever is always better than Sapphire, Beryllium etc. I’ve never owned a cartridges with Ruby or Diamond cantilevers, but i have owned a few with Sapphire cantilevers, and many with Boron, Alluminum and Beryllium cantilevers. Titanium has been used as well by various manufacturers. Audio-Technica used Gold Plated Boron, Stanton used Sapphire coated Alluminum... Miyajima top of the line Madake cartridge comes with exotic Bamboo cantilever, but lower models are all made and tuned with Alluminum cantilevers (Miyajima-San said that the most expensive cantilevers does not make the sound of his cartridge any better). Legendary Krell and Cello aka Miyabi MC cartridges designed with Alluminum cantilevers. Ortofon SPU Royal GM MKII comes with alluminum cantilever and the most advanced and the most expensive Replicant 100 stylus tip (aka Fritz Gyger). The best Fidelity-Research cartridges with Air Core (PMC-3 and FR-7, FR-7Fz, FR-702) also comes with alluminum cantilevers and those cartrs considered the best of the best. So having the Boron cantilever is not always necessary. Some well designed cartridges are just better than others!

here is some info from JVC Victor add:

Density (gr/cm): 1.84 Beryllium / 2.69 Aluminum / 4.54 Titanium

Young Modulus (kg/mm): 28,000 Beryllium / 7,400 Aluminum / 11,000 Titanium

Velocity Of Sound Propagation (m/sec): 12,600 Beryllium / 6,420 Aluminum / 5,990 Titanium




If you owned a cartridge with a sapphire cantilever, then you also owned a cartridge with a ruby cantilever, until proven otherwise.  In audio, they are one and the same material, I think. And so does Raul, for one other source.  I am open to consider any evidence to the contrary, however.
@rauliruegas @lewm
sorry I should have been more clear. I understand that sapphire and ruby are the same material (outside of some trace elements of chromium to give the red color).
Jico uses sapphire and ruby to differentiate between a tapered (ruby) and non-tapered (sapphire) cantilever. So the ruby is more expensive since it requires additional manufacturing to further shape the tip of the cantilever.

Here is the text from their website
Similarly the neoSAS/R enjoys all the benefits listed above with one crucial advantage:The four facets of its crystalline ruby cantilever taper toward the diamond tip. This tapered ruby cantilever design allows for lower moving mass, giving the neoSAS/R even greater ability reproduce vibrations in the record groove with precision, accuracy, speed, and fidelity.

My curiosity was if that additional tapering and thus tiny amount of less material and mass at the tip actually did alter the sound of the Jico neo-SAS and if this was worth double the price on a replacement stylus. The ruby/taper is only available for a small number of cartridge bodies and the Victor Z1 is not one of them.  So it was more if it would be worth trying to get one of those different bodies in order to try the ruby/taper. Henry answered that question sufficiently for me that I will be content with the Jico neo-Sas(S) for my victor Z1 and not bother to chase down alternate Jico/sas/bodies.

dear nandric,
I wasn’t doubting your comment about jonathan carr saying he does not like to use sapphire cantilevers. I was just more curious what he found out in his experiments/experience that helped him form that opinion.
