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

Don't take me wrong but it seems funny to me that MF discovered the 4point as the last in the row :-) To have a fair comparison one needs to run both arms (Airline and 4 point) on similar TTs with the same arms and carts which I did. Memories from a test long time ago are not a great support for real comparisons.

You make a good point about too much time passing between reviews to make a reliable comparison.

Part of it must be that the 4point was introduced years after the Airline. Or so I seem to recall.

Jameswei, you are right, the 4 Point arrived later, at me in May 2008.the Airline I have since December 2005 (I believe it came to market in 2004). It was one of the first units of the 4 Point I received and it was a pleasure to compare both units. In the meantime Mr Kuzma did some small improvements on the headshell etc.

So, sorry to revive ancient history, but where did you guys come out on the Airline v. 4 Point debate? Did anybody have both set up at the same time for comparison? I've been using the Airline for a while, the arm is great, the pump is a PITA. I'd love to get away from it, and go with something that requires less attention, but obviously, I'm not interested in compromising the sound. Thanks and hi syntax, nice to see you.

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.
More to discover
