Raul, I am not sure people understand the different types of balance tonearms can have and how they affect performance.
Tonearms either have Neutral or Static balance. Static balance is what you usually have. Balance the arm so that it floats perfectly horizontally. Lift the headshell 1/2 inch and gently let go. The arm will start oscillating up and down looking for the balance point which it will eventually find.
Neutral balance is more difficult to achieve. The center of mass at both ends of the arm have to be in line with the pivot. Carry out the same procedure as you did with the static balance arm and when you lift the headshel 1/2 inch and gently let go it will just stay there motionless. Anywhere you put the headshell it will stay. This is what you want in a tonearm, much superior warp tracking. Static balance arm bounce on their cantilever and if the warp is bad enough will leave the record. A neutral balance arm will not do this. To be neutral balance with all cartridges you have to have an adjustable counterweight like the Schroder CB or the Reed 2G. I think the Tri Planar is also a neutral balance arm. The SAT arm interestingly is not. It is Static Balance all the way and it's vertical bearing is high above the record another no no. The Schroder CB will outperform the SAT arm all day long. So why does Michael Fremer like it so much? If I had to guess it is expensive and it looks cool. An expensive, very well made poor design. Go figure
