My previous posts in this thread were apparently a little too basic f/some of you, when it comes to differences in the various models performance specifications.
Printed specs, as shown on the Ortofon web site and in the literature, are good for comparison between models but have only partial bearing on how the cartridge will sound in practical applications.
Unlike other electronic components, whose tested specs can reflect on how they will sound/perform, phono cartridges and loudspeakers, as tranducer devices, can not have all there parameters measured in the same way.
Cartridges, in particular, are tested using a "test record" and computer set-up which may or may not be close to what another manufacturer or reviewer uses. Notice I said tested not designed.
So, in the real world, 2 cartridges having exactly the same frequency response, ch separation, distortion, etc. can "sound" completely different. This is true with DJ carts as well as our $2,000+ Audiophile cartridges. Likewise, their interaction ( just like speakers) w/other components will color what you hear and determine which model is best f/you. Grand Master Flash is a regular visitor to our offices and has had the opportunity to use many of our models. His favorite is the CC-DJS -Blue. The list could go on and the favorite changing w/ each DJ and every country.
You will notice, on the Ortofon site, and as some previous posters have listed, the specs are actually quite close among the Concorde and OM models (spherical styli). The differences are attributable to the design and construction of the oscillating assemblies within the stylus unit. Meaning the cantilever (the hollow metal tube that holds the diamond tip), the magnet material, the damping design of the rubberized suspension and the quality of the diamond stylus itself.
The pole pins and coil assembly in the bodies are the same among the Concordes and the same among the OM's. You'll notice the "resistance" and "inductance" specs are the same. The coils are a major contributor to the amount of output, but the combination of the body and stylus determine the final output and sound/performance of the cartridge.
As I have previously posted, the performance and tracking ability can only be fully reached if you stay within the manufacturer's tracking force range. Interestingly, you can cause more problems tracking too light ( the stylus can bounce around in the groove). That's why it's always a good idea to be in the middle of the suggested range.
Please understand that I don't intend this forum to be a platform f/ pitching Ortofon products (I believe their perfrmance speaks f/themselves -

), just trying to clear up common mis-conceptions.
Finally, here's the tech info :
1. Yes, in spite of some posters disappointments, all the CC and all the OM bodies internal construction is the same.
2. The Stylus Pro S (black) has a stylus tip diameter/radius that is wider than the other models (r26 vs r18) and was first designed to play MONO LPs that have a wider groove than stereo LPs. Yet it is completely compatible w/ stereo. The other models however, are NOT intended to play MONO LPs.
3. Keeping # 2 in mind, the narrower tip radius will track deeper into the grooves ("V" shaped} of a stereo LP and have the capability of better performance.
4. The newest models, CC-NCS, DJS and Scratch, benefit from the newest stylus designs ( As do the Broadcast models, which we do not import into the U.S.- same as a NC , but color difference only).
5. Differences in cantilever thickness is less of a performance issue as it is a carry in your pocket, without a stylus guard issue. However, on the DJS and Scratch it can be subjected to very aggressive scratching, (I have never, ever heard of any other model's cantilever bending or breaking as a result of heavy use. So, this is a "tested" feature only at this point.
6. I would also mention that price differences among models don't necessarily reflect a "best" or "better" choice. It should always be an application choice. For instance, an elliptical stylus is the choice when better sound quality is desired for use in a quite environment or when transcribing records over to tape (or dare I say it, CD). It certainly isn't the best choice for
use in a noisy club, on an unstable platform, aggressively back cueing/scratching.
I hope this has cleared up some of the questions/misgivings that have been lingering. Debate on what's "best" will be an on-going discussion I'm sure, and I 'll continue to try to answer your questions as best I can.
