Has anyone had experience with the Schroeder Arm


In a high res setup has anyone been able to compare this arm to the top pivoting competition.I think that the fact that the pivot is magnetic as opposedto a bearing like a unipivot(needing damping) should on paper be less resonant and maybe sound better.I currently own,and,am happy with a Graham 2.2,but the idea of a true frictionless bearing (all bearings have some degree of friction)really could make a real difference in a good setup.I'm not interested at the moment in straight line trackers with air bearings (although I love some of them)due to the hassle of external pumps and tubing runs.

Mr. Schröder did you try to use the suspension tring from the Reference model on models 1 and 2 tonearms? And what were the results. I totally understand if you decline to response. Thanks
The effective mass for frictionless suspended tonearm are different than friction tonearms (unipivot or gimball tonearm). The armtube for frictionless tonearm is much heavier so it can absorb stylus energy. This energy then dissipated by the string, silicone viscousity, or magnetic field. Medium and low compliance cartridges are better match for suspended tonearm like Well Tempered. If you can find how Mr. Well Tempered calculated effective mass then substitute magnetic flux for viscousity. It's basically a Bernoulli equation for energy conservation. The reason that string supported tonearm are more musical than ball bearing tonearm because string reasonates like guitar or violin string. We don't find many musical instruments made of ball bearings. At the Rocky Mountain Audio Quest, I tried to get Mr. Well Tempered to visit the Teres 360 and Shroder tonearm so he can kick himself for not including magnetic damping with his viscous damping tonearm patent. It took over 20 years for Frank to get a patent on it. Of course, magnetic is a little harder to see than liquid even though electrons flow like water.
Frank, Did you make tonearms with magnetic damping since 1978? If your current tonearm was in the market 20 years ago, there would not be any gimbal nor unipivot tonearm designs. I also found that the gap between the magnets can be changed to compensate for the magnetic field strength in order to obtain the desired damping effects. The skating torque can also be independently adjustable regardless of the magnetic field strength. I guessed you already know those. I also noted that tonearm builders like music instrument makers. They both bring music to live.
Mr. Schroder, Thanks for your responds and information about tonearms. I found www.diyaudio.com which more interesting to me.
