ct, Michael Fremer is FOS. He uses a SAT arm "the best sounding arm ever made." By the way the largest benefit of a linear tracker is not reduced tracking error. It is no skating force in theory. The major defect is a horizontal resonance that is going to be too low or a vertical one that is too high messing up the bass (most common)
No linear tracker except the Walker has survived the test of time. With the exception of the Clearaudio they are all inherently more complicated and prone to failure and deteriorating performance. The Clearaudio is prone to dirt. On the other hand a good pivoted arm is immortal as long as you don't drop it or let your wife use it. Skating is controllable within limits and tracking error can not be heard. I personally have never heard a linear tracker sound better than a pivoted arm. I have never heard one sound as good as a Kuzma 4 Point 14 with a Koetsu in it.
