These two guys have it right. Having been an owner of two Graham arms and now using a state of the art air bearing linear, I agree with everything that has been said.
It is more difficult and parts intensive (pumps, hoses, regulators, gauges, etc.) to get an air bearing installed and working, and unless it's done right, it can be worse than a pivot arm.
The Air Tangent from Sweden immediately comes to mind. I had one of these beautiful $10K arms over three months and never got it to perform as well as the Graham 2.2.
The Rockport and Walker linear air bearing arms provide another level performance over a Graham 2.2 or any other pivot arm. These two linear versions also represent a HUGE investment compared to the best pivot arms.
Unless the remainder of the system is up to the task, this is probably not be the first or most economical place to upgrade your music.
