A.T. M. C. cartridges

Post by eddiep » 15 Nov 2019 02:22

Any opinions about the A.T. moving coil cartridges other than the Art 7 and 9, such as the OC9 and AT33 series?

I'm also really interested in those.
Most of the OC9 based types have a 100Hz compliance of 16-18.
Has anyone measured that at 10Hz? Exception to this seems to be the AT OC 9 ML/II with 9 x 10^–6 cm/dyne (@100Hz)
The AT33 series seems to have a 10x 10^–6 cm/dyne (@100Hz) so these grab my attention.
Any descriptions on the acoustic signature?

I’m still curious why MC cartridges don’t have user replaceable stylus.

Some MC cartridges have a user replaceable stylus. There have been multiple models in the past

But it's quite difficult to make, as the coil has to be replaced at the same time, which makes it also pretty costly.
When you have a stylusassembly that costs almost as much as a new cartridge, and when it makes the cartridge in itself also more expensive, it makes less sense to do so.

Sometimes I even wonder why some mm cartridges have replaceable stylii. If a stylus costs €169,- and the complete cartridge costs €175,- (with for instance an AT-vm95sh)

I don't own any of the new model OC9s, but I do have the OC9ML/II, as well as the AT33PTG/II.

On my system these are two very different animals. The AT33 is very nuanced and exhibits none of the extra sparkle in the higher frequencies that some describe as the general AT sound. The OC9 has, again on my system, a boost in the upper mids, perhaps a little into the higher frequencies.

For close listening, and for music like hard rock with congested/competing instruments I prefer the 33PTG. That said I consider it my swiss army knife of cartridges. It plays everything well.

If I'm on my feet moving around the house, the OC9 seems to penetrate better. For close listening to music like jazz or perhaps something like Steely Dan Aja, it's awesome. For close listening to something like Led Zeppelin, in my system, it doesn't tease out the instruments as well as the 33PTG, and it can be somewhat fatiguing.

I've enjoyed my OC9, but the 33PTG is my favorite, which is why I have two of them, and why I've offered my OC9 up for sale here, unfortunately to no avail. I thought someone here would want it.

Audio Technica had one in the past (AT-3100) not very successful though...
Obviously because of the cantilever mounted directly to the generator makes it a very difficult part to make replicable (at a price that makes sence)

I love my OC9ML/II, I'm a big fan of this cartridge...

I own the AT-33PTG/II but none of the others on the list. It’s my current fav. It’s warm, detailed with a has wonderful range in my system. I have a great comparison just to the right. It’s a Hana EL. The two sound very close in presentation but the AT is slightly better in the upper frequencies.

Yes there is no realignment, but easy upgrades is of course the same. My statement had meaning on my second sentence, where a 'stylus upgrade is only €6 cheaper than the complete new cartridge.

And realignment is pretty easy if you have a separate headshell. You just need to measure the distance from stylustip (or in this case as the body is the same: any part of the body) to any fixed point on the lateral axis of the headshell and set the cartridge to that distance.
