Shrinking the moving magnet phono cartridge

Ғылым және технология

If a moving coil cartridge is better because of its mass, why not shrink the mass of a moving magnet's mass to match?

    The advantage would be still an interchangeable stylus, even if all other parameters (such as output) were identical.

    There are low output non-MC cartridges like those from Grado Labs & Soundsmith, which are "moving iron" cartridges, which have low mass, as well as be run into a MC phono stage.

    Still using Stanton 680/ 681 series moving iron. Very nice sound stage. Extremely versatile with a stylus for every purpose. The nude mounted ones are pretty low in mass. The ease and cost of replacement is certainly a benefit. It's a shame that Gibson dropped the ball on Stanton It's the 681 has been my go to since1978. Thankfully Japanese aftermarket is pretty good for these .

    I've been well & truly "been bitten by the MC bug", having used them for over 30 years; including Audio Technica OC-9 & 3 Lyras - Helikon, Skala & now Etna Lambda. Prior to that I was a huge fan of Grado (& still am), having used a Signarure 8 Revised from 1984.

    Thats a fantastic question! And i dont understand why a shrunken magnet in a MM type might not be extremely desirable...a)it would give user replaceable styli b)the stylus would track more accurately. Well done for thinking of this smart question!!

    The question is fair and there are examples of cartridges made with such compromise obviously benefitting from lower mass needing MC phono input. I think one reason you don’t want to do it is the signal quality is less than MC.

    Who says MC has lower mass, copper coils on iron cross, all dense materials vs a rather small magnet of samarian- cobalt like on a Stanton. But it doesn’t really matter as all that mass is in close proximity to the pivot point and contributes little to the inertia, like the heavy counterweight in a tonearm. The cantilever and stylus are far more important. Tapered aluminium is probably the lightest, and small shank stylus, also shorter cantilever (some Dynavector). In the 70’s exotic MM cartridges with unobtanium cantilevers(tubular beryllium, boron or sapphire) would state their effective mass in spec sheets, nobody does that anymore. The top MC cartridges today use heavy diamond cantilevers, so light mass is not what drives performance. Maybe it is market driven, Soundsmith makes low output versions because that’s what people expect in an expensive cartridge.

    @@SpyderTracks All optical devices work in the analog domain. In fact you could take a LED, shine a light on it, and generate a tiny voltage. If you could wiggle the intensity of the light, you would get a tiny analog AC noise across the terminals of the LED. IDK how DS specifically designed their phono setup, but it is entirely possible it is analog.

    The voltage output is a direct relationship between the number of coils moving through a specific magnetic field. All else equal, smaller magnets would be less voltage. Moving them down into the MC area. Variable reluctance. Fixed coil and magnet structure. Moving metal between them to vary the magnetic field that way. The metal is far less mass than either a magnet or coil. Acutex came out with a line using this after Audio Technica came out with their line which had the patented dual magnet V design. AT sued Acutex because they copied the dual magnetic V structure patent.

    Stanton once made some moving-magnet cartridges that had the low output of typical MC cartridges. I don't see much point in those products, unless they reduced the mass of the magnet, accepting a reduction in output voltage. I'm wondering if Stanton did exactly what the query suggests.

    Pickering has made exactly such cartridge in the past (I believe something with 7800 in the model name). I would call that a proof of concept. It was highly regarded as well. So if you ask why they don't make it any more (under the Stanton name)? I would say it is not a given that it was not good enough. I guess they lost the know how. The same happened with Shure, and sadly they gave up on phono cartridges all together. Stanton is holding on for dear life. You could conciser them a Zombie company.

    For once Paul seems to have sidestepped the question, although he seems to understand it. Two (dominant) wiggly groove playback technologies: MM high output plus high moving stuff mass negative; MC low output minus low moving stuff mass positive, wires connect to stuff attached to needle, negative (and nobody seems concerned with the necessary bending of those wires adding to inertia). So why not strike a balance by reducing the mass in a MM?

    Maybe it's a "stylus" to you highfalutin types, but "needle" was the term that was always used back in the day. (As in, you started playing a record by "dropping the needle" on it, never did I hear "dropping the stylus" used.) And, yeah, I bet he'd get in meetings with the top cartridge engineers these days and use "needle" without shame or embarrassment, because old farts like us don't give a dang what young snobs think about nonsense like that.
