Great bass from a linear tracking arm?

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

Exlibris,

"Optimal cartridge weight: <9gm."

Where did you get this spec? It's not listed with the others on the Kuzma site. I'm also interested in this arm as well as the OL Enterprise.

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

Joperfi, please read Rushton and my post at the start of this thread. With linear arms, cartridge weight and compliance are (somewhat) more critical than with pivoting arms.

Or to put it another way, if you have a cartridge you love, you can always find a high end pivoting arm that will work optimally with it. But if you've commited to a linear tracking arm, you have automatically narrowed your choice of cartridges somewhat -- due to the fact that the armwand+cartridge weight+cartridge compliance must all be within certain parameters for the entire mechanism to work properly.
.

To continue on Rushton's remark:

"design of the arm (e.g., bearing rigidity) has a huge impact."

The Walker, the (now defunct) Maplenoll, which I own, and the Kuzma are all very high air pressure designs although the Kuzma's bearing is much shorter. The ET runs on about one tenth the pressure and is consequently not nearly as stiff. Although it's impossible to do a direct comparison of an ET arm to a Walker or Maplenoll given that the former are both integrated tables, I imagine that this stiffness has a huge effect on everything including the bass reponse.

I know that if I reduce the pressure to my Maplenoll arm, tonality suffers noticably.
