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….

@nandric   I did a search of jcarr and sapphire and could not find the comments you are referring to. I just found his mentioning of Namiki running out of boron cantilevers so they could no longer supply their stylus mounted on boron to manufacturers, and his comments about difficulties of manufacturing with boron cantilevers and that his sources for boron cantilevers are a trade secret now.

Can you provide the reference? I would love to read his comment.
Hi Halcro
Thank you for this report. I was wondering about the Sapphire vs Ruby and how it compared to the original boron. Really glad to hear from your report that the neo-SAS is just as good as the original boron-SAS. I guess the ruby might give a tiny difference in some special cases, but most likely it is maybe just to appeal to some vintage enthusiasts who lovingly remember the dynavector rubies. My guess is that they changed the manufacturing to get away from the bonding to boron, since many people think bonding is a "cheap" technique for such an expensive stylus.

Not sure if you ever saw this thread over on VinylEngine but it gives lots of good info on stylus shapes.

The consensus is that the SAS is Jico’s name for the Namiki micro-ridge which was patented back in 1983. It also appears that Jico might be a sister company to Namiki, but this is harder to confirm (Namiki does the cutting and maybe Jico does the assembly). Also since this stylus shape is laser-cut it seems that Namiki might be the only company with the technical skills to make these so probably all micro-ridge/micro-line (AT-ML, dynavector 20x 17d3, lyra delos/dorian, Jico SAS) are actually all Namiki micro-ridge styli.

Thank you for trumpeting the glories of the Victor Z1/SAS. I’m enjoying mine immensely. I also love the look of that translucent sapphire cantilever and this neo-SAS construction does look world-class.
Dear Nandric, apologizes for not catching your meaning.

At least my search probably explains why Jico had to switch from boron/SAS to sapphire/SAS. It might be the simple case that they get their cantilever/stylus from Namiki, Namiki has run out of boron cantilevers, has the in-house manufacturing capabilities for sapphire rods, and thus can only supply their micro-ridge/SAS mounted on sapphire, ruby, or aluminum (simple supply chain and manufacturing issues driving product changes and Jico making the best of the situation available to them).
@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.
I just want to comment that before we get too convinced about this "boron shortage", the comment from jcarr I referenced above was explicitly that Namiki (probable primary supplier for Jico) has run out of their stock of tubular boron cantilevers. Jcarr has an alternate source for boron rods which he still uses in his cartridges. If there is any shortage it is for the tubular boron (not boron in general)
jcarr320 posts07-01-2014 2:34am
Fleib: Namiki still keeps stocks of tubular sapphire cantilevers, and possesses fabrication abilities for the raw sapphire material (I believe). OTOH they do not have any more tubular boron cantilevers, and I do not believe that Namiki were ever capable of making the raw boron material or fabricating it into tubular form. Studying the patent literature on tubular boron suitable for use in phono cartridges reveals that the majority are by Matsushita (Panasonic).

If you (or anybody else) knows of a material manufacturer who can fabricate tubular boron with an outer diameter of 0.3~0.5mm, or anyone possessing reasonable quantities of the same, please let me know. FWIW, the same applies for boron rod with an outer diameter of 0.3~0.4mm. It would be welcome news for Ogura and Namiki, and by extension all manufacturers who use their products
.....
Cantilever assemblies can be built completely by the cantilever manufacturer, but it is not unusual for the cartridge manufacturer to provide raw materials and/or prefabricated components so that the cantilever manufacturer can complete the cantilever assembly properly per the cartridge manufacturer’s design.

If the cantilever manufacturer has stocks of the appropriate raw materials and is able to fabricate these properly, it is usually easiest for the cartridge manufacturer to ask the cantilever manufacturer to source and make everything. But if the cantilever manufacturer doesn’t have the needed materials or capabilities, where the cantilever’s internal components come from and how they are made is up to the ingenuity and resourcefulness of the cartridge manufacturer. In the latter situations, neither the cartridge manufacturer nor cantilever manufacturer may be willing to reveal where what internal component originates from.
...
Regarding diamond dust coatings, we supply diamond-clad boron rods to Ogura for inclusion in our upper-model cantilever assemblies. Our goal is to suppress out-of-band (ultrasonic) resonances and increase rigidity; I assume that Nakatsuka-san’s goals were similar.

ps: I’m still loving my new Z1/neo-SAS. If there is any "problem" it is just that it is so revealing that my attention keeps shooting around the performance (like watching fireworks, wow hear that bass, oh wow can really hear the room ambience now...) and it is a bit hard to just relax and take in the whole performance. But I suspect after the newness wears off, I should be able to holistically enjoy the performances again.
