Great bass from a linear tracking arm?

After getting my ET2 arm dialed in on my VPI HW19 Mk3, with a little help from Bruce Thigpen (a benefit from living in Tallahassee),I find that the ET2 is delivering excellent bass response, and that's using a well broken-in AT-OC9, which is not at all a light cartridge at 7.8 grams. Also, I might add that the bass is much better now, as well as the overall presnetation, than with the same cartridge in my Linn Ittok arm/LP12 table.

If you have any doubts on what works and doesn't on air-bearing linear-tracking arms, send Bruce an email and I'm sure he can help you out. After all, he invented it and cousults to those who build them.

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.
