Shure SC35C with JICO SAS

[dlaloum]

I just picked one up (at a good price) on the bay... an M35X...

Tested the inductance and resistance.....
Inductance 423.5/424.5 mH (!?!?)
Resistance 993 / 999 ohm (!?!?!?!?!?)

That is on a par with the very very best hand picked cartridges that I have.... I have an AT20SLa that is on a par with that, but nothing that betters it....

I then looked at what styli will fit...

It is a "broad shank" shure model, with a standard cantilever angle... so the N97xE shank fits, as does the VN5MR... BUT - the cartridge surround is such that these styli cannot fit - their plastic surround is just a bit too high and the wrong shape....

Also the cartridge weighs in at 6.2g where a V15Vx is 6.8g - so it is marginally lighter - an advantage if running with a high compliance stylus like a SAS...

I do have a SAS that came loose from its stylus holder - so it is "Naked" - very handy in this case.... I look forward to making a direct comparison of a V15VxSAS and the M35X-SAS.
(this is most likely some months away though!)

bye for now

But, as posted, that might well not translate to matched generators, and might well be swamped by other factors. Personally, I don't consider close matching of basic coil parameters to be a particularly useful figure of merit. Only if it's a long way out might I suspect something is wrong. There are so many other contributing factors involved in overall channel balance and matched characteristics. Focussing on two arbitrary factors just because they can be measured doesn't tell us much about the whole picture, really.

Measuring comparison between a V15 and the M35 with the same SAS stylus in each body will provide a better indication of what is going on in there....

Yes the fact that the channels are extremely well balanced is only one factor - but it was the type of factor that Audio Technica used in seperating the AT20's from the AT15's, and which Grado use in seperating the Gold's from the Silvers...

Each little bit counts - and through sheer unexpected pot luck this particular body is exceptionally well balanced... (better than any of the V15's I have measured)... quite a surprise really.

I will in due course measure response and see whether the two body type have the same performance...

Yes, there's a philosophical point here about the nature of tolerance build up. Every little bit counts if you're making thousands of the things, and want the end result to be consistent for all of them. But if you've only got one, the optimum for any parameter depends on all the other specifics. And optimum might well not be close to spec median, for a one off......if that makes sense !

Plus I'm not convinced that those coil parameters necessarily define generator performance, not least for the reasons already posted on this thread.

In any event, channel matching (not just level) as an end result often varies quite a lot in measurements. But it's been a long time since I've noted an audible channel difference due to a specific cartridge, though I'm sure it must happen.
