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,

Music is rock and alternative (whatever that is these days!)- nothing too heavy or out of the norm. Setup and compressor noise are two concerns, l am pretty limited on compressor placement due to house layout and construction. Setting it up in a cupboard in the listening room with a wooden box over it might be easiest.

The arm has to be perfectly level and that worries me a little, my rack is very heavy and on 4 spikes, a real mongrel of a thing to get level, l understand the Airline is very sensitive so that could be tricky.

If the 4P is considered soft then the Airline might be a very worthwhile upgrade.

Thuchan, those were my thoughts. Cartridge matching would be very important. I see the FR-7f is 30grams and low compliance. Yeah, heavy cart would be my guess also. However, I might tend toward more compliance. Stone body Koetsu comes to mind.
Since Kuzma sells (or used to)rebraded ZYX carts l reckon my 4D is a pretty safe bet on an Airline.
Syntax, the 4Point is not as you describe. Perhaps there was a gross mismatch with the cartridge, or maybe the cartridge was poorly set up or imcorrectly loaded. Big, bold, dynamic, tonally rich, low noise, and nuanced are what my customers and I hear. But don't take my word for it: certainly in this price range one should pursue an audition.

Dealer disclaimer.
Thanks for the feedback in this thread. l have committed to buying an Airline so will have all the answers in a week or so :)
