Kuzma 4Point vs Airline - is it worth the upgrade?

l have owned a Kuzma 4Point arm for a few years now mounted on a Kuzma Stabi XL2. l have the opportunity to change to a Kuzma Airline and was hoping to hear from members who have heard both and whether they think the switch is worthwhile. There is not much l can find on the net comparing the two.

For a similar cost l could add two motors to my XL2 converting it to an XL4, could the upgrade there be more significant than the Airline vs. 4Point?

Interested to hear fellow 'Goners opinions.

Cheers,
Simon

The 4P is an excellent example for engineering which fails the sonic spot by a mile. Soft dynamics, soft soundstage, everything wrapped in clothes, a real sleeper, one of the biggest disappointments I ever listened to. But probably the right Arm for harsh, shrill reproduction Systems. It will compensate a lot.
The Airline has one big advantage: It shows the user that such a Design can work. It is better from dynamic response than the 4P (no big deal honestly), better soundstage but it won't tell you anything new when you have one of the better Arms. For that money my favorite was the DaVinci Arm.

One of my friends owns that XL Table with 2 motors, he loaned 2 more and gave them back. He said, it it not worth it (for him). He also owns a Airline.

Hi Whart,
sad to hear that you are not in love with that pump :-) The one I had worked
day by day without any problems or noise (there was an additional valve which
can be closed to reduce noise). Normally it is simple to replace the unit (I would
do that). There are lots out there which are used for dental labors and they
aren't expensive.
