Great bass from a linear tracking arm?

"Optimal cartridge weight: <9gm."
This comes from the 'specifications' section of the Stereophile review from 2004.

Very good. Thanks to everyone for their responses.

Rauliruegas,
I've enjoyed reading your informed posts on cartridges.
Perhaps you would like to chime in on this thread:
Best Cartridge for Kuzma Airline

Here is some information about the Kuzma AIR LINE:

Recommended cartridge compliance: Below 25 cu
Optimal cartridge weight: <9gm.

Effective length: 184 mm
Effective mass: 13 gr vertical
Minimum clearance below platter: 30 mm
Mass: 2 Kg

The Brinkmann EMT Titanium phono cartridge is 11 grams.
Maybe the one you were using was quite different than this?

The ZYX Airy 2 and Airy 3 are each 5.0 grams. I believe the Universe is either 5.0 or 5.5 grams.

A person I know who currently owns a number of Airtangent arms (though not the current '2002' model) says that the key to great bass is not higher pressure but a light cartridge.

For $11,500 the Air Tangent should come with a compressor that doesn't have pressure issues. One shouldn't have to 'tweak' an arm that costs this much.
In this respect the Kuzma Air Line seems to be a better design and to represent a better value.

I enjoy reading your posts but you make it difficult to do so by omitting spaces after commas, periods, and other punctuation marks.

Kuzma's air bearing is specifically designed to work under high pressure but the Air Tangent's isn't. I wonder how well the AT would physically hold up under high pressure over the long haul?

As expected there has been a lot of discussion of linear trackers that use air bearings.
What about the offerings from Clearaudio that use gravity, wheels, and tracks? I've read about some of the operational problems that one can encounter with these but what about the sound? When everything is working well are these comparable to the very good air-bearing designs?

Thomasheisig,
I would imagine that the Kuzma/Universe combo is so good that it would be hard to go back to the Phantom or DaVinci?

The ZYX UNIverse without the silver base (SB) is 5.0 grams.
The compliance horizontal is 15 x 10-6 cm/dyne and the compliance vertical is 12 x 10-6 cm/dyne.

I'm not surprised that Kuzma is using the ZYX with his linear tracker. I 'did the math' (according to the formula at the VDH site) and both the ZYX Universe and the Airy 3, on paper at least, work great with that arm.

I think that the Airtangent may have a slighter lighter effective mass than the Kuzma which leads one to believe that an extremely light cartridge with a medium to high vertical compliance would work really well with it. Since we don't want the horizontal compliance to be too high (tail wagging dog) it is probably best to go for a really low mass cartridge to get the math, and the bass, to work out nicely.
