This is still debated in other thread. It's not a fact.

Yes, its not a fact. Where is the 'other thread', flavio81, I've missed it ? Would be interested to read/discuss.

Thanks, I'll do some searches on osmium tip stylii.

Great One....that post speaking of the dangers of MR stylus, and the bad beryllium cantilevers, and how inferior they are, along with the Shure V15IV being conical was one of the most bizarre posts Ive ever read. Imagine a newbie that read that as gospel truth. Glad some humor was added. Ray

I've got the cracked stylus and can show it to you. Berrylium is extremely strong, and does not break without quite a bit of force. Of course a broken or cracked stylus is extremely delicate. Cantilever mass has nothing to do with VTF in my statement above. Cantilever mass is the amount of cantilever in your sound (cantilever haze). Yes, MRs are very touchy on the set up side. VTA was Shure's priority when building the damper brush. I know what 2nd harmonic distortion is. A newbie will not ever understand good sound (I doubt most people even get to hear true treble brilliance with no haze at high levels-it is a total atmosphere). Shure's famous HE stylus came out in the early 70's. Shure was famous for many designs. The MR came out 10 years later. The original V15 IV is a radical diesign unlike any other V15 styli.

PRATICABLE AND PRACTICALITY ARE THE MAJOR FACTORS. KEEPING UP WITH THE COMPETITION REGULATES WHAT MATERIALS CAN BE USED. If you own a V15 MR and your stylus is finished, you either have to learn about styli, or purchase a Dynavector with the MR, because you will never get the original V15 sound back. The V15 5 did not have the sound of the 3 or 4, and the V15 VxMR was not even a qualifier for Shure's idea of performance. 30 years of listening to V15's will render you defenseless to any other cartridge under $900.

If you were around at the time, the V15's were well known to be one of the best carrtridges available, and had many "flavours" of styli.

The stylus output level (meaning how loud the stylus is) is a big factor in choice of materials. Grado cracks their styli.

Just a little off the topic, I now remembered what we could do with tube amps that we could not with solid state without 300v power supplies.

Go easy there my friend.

Some of what you have said is very interesting. I have a few of the Shure carts, but most of the ones I listen to are Grado Statement Sonata's with nude eliptical styli. I know people that have been spinnig for years that have not refined their systems for better sound . They just like the old equipment and TT's. A few are still trying to figure out how to set up their TT's properly.

Don't judge newbies until you know them, doesn't mean that they do not know good sound. Some might have a better ear or equipment, or want to know what they need to get that sound. When I was a kid back in the 50's I grew up on $1500.00 tube equipment. That is why I am still in vinyl today because of that sound. I learned at a very young age what quality sound can be. You do not know how many newbies have heard great sound.

The job of this forum is to help them learn and grow. Face it we all learn something here daily if we want to listen to the group. I am not picking on you at all just reminding you of our purpose.

As far as the humor, don't give me much credit. I am paraphasing "Blazing Saddles"/Mel Brooks.

Odd thing is there were Shure replacment styli for some of the older Shure V15 that were conical. These replacments had a "G" in the model number (III-G and IV-G). I recall a bit of a cult following for them briefly in the 1970s and '80s.

Never mounted nor heard the "G" stylus in either my V15-III or IV. (wish I still had the bodies cause I would love the hear 'em with a Jico SAS...or just flog them on ePrey where they bring stupid money now)

I believe there was no "G" stylus for the V15-V.

G STYLUS

Postby rayr0683 » 21 Sep 2009 22:11

Wow....Interesting. See you do learn something here everyday. I just did. I was not aware of the G stylus, which is why I assumed the IV conical bizarre. In all the vinyl forums I belong to, whenever I read about the IV I always seem to read most about the HE....but since there was a conical, and noone seems to mention them, at least in all the posts I have read. i wonder how many are floating around, possibly new?? And if they had a cult following, they must have had an interesting, or good sound, so they may be worth a try, if any show up NOS on Ebay, or in Classifieds.

At any rate, with whatever knowledge level I do have. I still am finding myself very confused by all of this. And in speaking with a Shure Designer, designer of the ML140HE...Les Watts....he indicated that berrylium was used for a reason, not to cut corners, but felt it was the best choice as cantilever material. In fact, he wanted to bring back a new cartridge, with beryllium cantilevers, he has a lab, and a laser cutter of some sort, and was gonna get beryllium sheets, that he said he could then make new cartridges from. This was all on Audio Karma. He was very nice and informative, and emailed me personally with all of his ideas, and the reasoning behind Shure's engineering designs back then, and when beryllium was discontinued. It was all interesting, and I posted his quotes in this forum back when we had spoke. Many members found it very interesting as well. Ray

The conicals were actually only of interst to professionals and archive people.

The idea of the break in the cantilever was only meant as an example of mass reduction. The massless tip is quite 3D. Obsessed stylus designers know where I'm at.

I understood berrylium is actually sprayed and not cut from stock. Berrylium is of course a non compromise metal for strength, durability, thinness, and very high resonance. That is relative only to the marketability of a stylus that better last 10 years. As well, the tiny MR stylus needs a strong bond that won't permit standard metals. Think about such a stiff substance riding on your vinyl. I doubt Shure needs to be in the cartridge race anymore. But if people are selling NOS VN 5MRs for $500, they may want to consider that.

Back to what I said about the V15's priceless, what they can't perform in weightless sonics, they make up for it in their trackability.

There are those posters here that seem to deal in confusion and obfuscation. If somebody writes something that seems to make no sense - and then cannot explain himself when challenged - he deserves to be roundly ignored. (..or occasionally "poked" for entertainment's sake)

Remember - everybody in entitled to their own opinion, but they are not entitled to their own facts.

I would say you have a very good insight on the Shure line from one of the designers. Very interesting.

Hey Kevin,

I really need to re-read his email to me, to understand it. I dont just grasp it, to explain out of my own words. But he, Les Watts is no longer with Shure, he did design a few of his own cartridges for them, while he was a designer/engineer there. Hehas his own business now, still involved in music and ausio, but told me that he has several labs. He wanted to market a new cartridge....in his mind, the best cartridge that he could make, and would still sell enough of them to make it worth his while. Since he does not have a large corporation like Shure Industries. So, he was trying to get ideas from fellow audiophiles, like us, as to who would be interested in such a thing, going back to using beryllium, or some other material he mentioned that was also very good, not anything that I am aware of currently in use by any manufacturers. I will look it up, and post it here. But its interesting what you said about the G stylus. I think Id probably like that since I do alot of archiving, from my vinyl to Open Reel Tapes. And I have so many that are 30-40 years old, all recorded on very good equipment, and those tapes sound as quiet in background as CD's, but have the beauty of analof that I love so much.

I do have a Shure V15V-MR LE that is still barely used, almost mint, and I dont know what Ill do when the stylus goes. Maybe this new Jico SAS V15V HE that is supposed to be newly released will be good?? Maybe not. I was also going to get a NOS Beryllium stylus for my Audio Technica AT20SLa cartridge, for $109.00, that is a real nice cartridge too.
But Les did warn me to be wary of NOS cartridges, ue to the degradation of the damper that the cantilever connects to. Oxidation can cause them to collapse, some have. But just so you follow me, Les wants to do a cartridge on his own. He did tell me about how Beryllium is used, and maybe Im misquoting him, calling it sheets. But whatever is useful of what he told me, Ill post back here. Ray

I'd have to agree that conical stylus Shure 15s were used primarily by pros and archivists, who eschewed Shure's other broadcast cartridges to buy V15s, but who also knew that a conical stylus will wear out 10-15% slower than an elliptical stylus. It also didn't hurt the situation that most of the radio pros worked in environments with severe bandwidth limiting, so high distortion at 14KHz didn't matter. Archivists were often playing 45s or microgroove 78s for posterity, and so they also didn't worry about high frequency distortion, because if there really are no high frequencies, there can't be any high frequency distortion. Denon made the Denon 103 series of broadcast cartridges because they were selling to radio businesses who knew the cost of 15% less stylus wear. So Denon 103Rs had conical styli.

This "cult following" I read about often works like this. A radio station engineer finds a way to 'STEAL" a phono cartridge from the radio station or perhaps the DJ says it would help to audition records with the same cartridge the radio station uses. Then friends visit the engineer/DJ and want to have this same cartridge for themselves, so they buy a few (status in this case is more important than audio fidelity). Since every person on the block has a V15 with an elliptical stylus, the status seeker stands out by saying they have something different, and they can even confirm that So-and-so the DJ uses the exact same cartridge (which is true, except that the radio station person isn't concerned about fidelity, and they get records nearly for free or free, and so record wear isn't important either).

Sometimes a V15G distributor had 200 in stock and went out of business. At the auction, a retailer buys them all. Then the retailer says that not only does the local radio statio use this cartridge, but so do many personalities (all of which can be achieved with freebies. I know because I saw audio company promo budgets for give-away products.) This makes for a "cult of product", which translates into the use of a product known not to be as good as another product for other reasons, and then promoting the users of the product, not the quality of the product. If an auction priced V15G at $15 sounds better than a Stanton 500A, at $15, that's nice, but it doesn't mean the V15G sounds as good as the V15 elliptical. If the V15G sounded better than the standard V15 with an elliptical stylus, then the V15G would be renamed the standard V15, and previously labeled V15 would get some name like the V15 E Special or some such, and it would be sold on technicalities, not sound quality.

Hundreds of "cult" items I was asked about often had conversations that went like this;

I'm in a booth at one of the 25 CE Shows I worked at. Someone says something like, "What do you think of the Blah-Blah brand/model cartridge?". My answer is something like, "It's not very good." Then the question person says something like "But So-and-so uses it". If So-and-so is a music-making personality like a singer, I could say, "Sure, but So-and-so would recognize their own voice over a tin-can telephone, and it isn't So-and-so's job to know what cartridges have good fidelity or not.

It gets worse if So-and-so is a conductor or band leader because there is no comparison between being a band leader tuned into what is turning on the audience, or a conductor listening in a record booth, and whether these people know anything about whether a phono cartridge has true fidelity or not. I learned this when I sold phono cartridges retail, to band leaders and orchestra conductors and I realized they usually bought lousy phono cartridges because it didn't matter to them. If they can hear live music that is made into records, they only use their own audio systems to listen to Other Musicians (or maybe they listen to tape dubs of yesterday's session to change arrangements or something). It was like pulling teeth to get most orchestra conductors to play their own records when I would visit to install a new amplifier or speaker system.

Obviously I'm leaving for last the people who were paid to say "I own a blah-blah and I consider it one of the best phono cartridges in the world". I always told question askers, if I knew that someone was paid off, to say some product was good (often the endorser had never heard the product, to show you how corrupt this all is. These endorsers often sold to unsuspecting people, the one phono cartridge of this type they got simply to fulfill the "Truth in advertising" stuff.

Once I had a friend who wanted one of these cartridges for his college student son. I bought it from a guy who endorsed the product, but knew it was about 1/20th as good as the cartridge he was already using. I paid by check and kept the canceled check as a souvenir. When someone at a CE Show asked the question about a phono cartridge and when he didn't like the answer, he showed me his give-away copy of Audio mag with the ad for the cartridge, I showed him the check and the cartridge, and offered to sell it to him for 5x retail. He bought it even though I showed what I paid for it, and told him it was a lousy product. All he cared about was that So-and-so had owned it (although didn't listen to it).

My advice is to find out out what print audio magazine reviewers (not cult audiophile mags) use in their own systems, and then ignore what they say in magazine reviews about other products and just buy what they use. Final note: I worked mostly for speaker companies and when I did that, I didn't comment about much about other speakers. But people never asked either, because they assumed I'd say "Any brand but the company I work for is terrible." If they asked what brand of speaker was, perhaps not ask good as the brand I worked for, but since they didn't like/couldn't afford my brand, what was nearly as good (but possibly less expensive, or somethings else)? Usually I just told them honestly. I could also say, "I don't like brand So-and-so." If pressed I could always say "It is considered poor business etiquette to bad-mouth some else's product, but since you can hear the differences, just by comparing them side-by-side, you will know when you hear for yourself."

Most people don't want to listen allot and study what they are hearing, so they know for themselves why one product is better sounding than another. They wanted me to say that "Well, if So-and-so says they use a certain phono cartridge, and they say it's the best in the world, then it must be." Expecting someone who knows allot about sound to say that, is ludicrous (and that's why they came to ask me questions; because other people at CE Show had told them I knew allot about sound [or those people who sent them to me were sadists, which I'm guessing was 50% of the time]). One thing I never did was to answer the "death" question; "What's the best audio ANYTHING?". Nothing is perfect. I stopped making fun of people after the 30th time I heard that question and just said, "Many ______ (you fill in the product type) are good, none is the best". In reality, none of the inquirers could afford the best of anything, which I found out when I told them, if there really was a "Best" audio product.

Today, people still ask me about whether Such-and-such is a better audio product of it's type, than something else. In many cases it is obvious, but when it isn't, I always ask, "why do you ask?" Usually I can understand if someone is trying to dump this item on the inquirer, or they read too much advertising or something. If it is just a well meaning question (usually because they are getting a low price), I can then say, simply and plainly, "No, it's not better than what you have already". If they need more than the briefest explanation, I tell them to listen to the 2 items side-by-side. If people don't want to bother themselves to understand why one thing is better than another, I won't contribute to their laziness.

Radio station bandwidth may be narrow, but harmonic distortion concerns are extremely important . The transmitter distortion has to be low,and controllable, listening fatigue and studio monitor playback 24 hours a day is a radio station's concern. People seem to forget that narrower bandwidth has to be high quality as well. Western Electric 300Bs were originally designed for telephone lines. Anyhow FM stations are still 30Hz to 15 Khz in the audio range. And AM can use remixing to highlight solos to improve narrow band value. (Good AM receivers are just difficult to design because AM's sensitivity to internal interference, plus external factors.) Too many audio[philes manufacturers simply don't understand there is more too fidelity than extended bandwidth. (It still sound sqwashed in at 20hz-20khz.)

Don't know what the 300B vacuum tube has to do with conical vs. other stylus shapes.

I do believe the 300B was developed by Bell Labs/Westrex (pre-WWII) for other uses then phone lines. It got it's audiophile interest from use in theater sound systems. Anybody interested should check Westrex history. A "Google" will get you there.
