Tonearm Geometry
When I was researching Amadeus, I decided to try a non-standard tonearm geometry. I introduced a tracking
angle error of 15 degrees and was surprised to find the musical result was better!! This led me to investigate
tonearm geometry further with unexpected results. To make a very long story rather short, tracking angle
errors generate 2nd harmonic components to the musical signal and many people interpret this as “sweeter
music”. I have written a computer program to show the amount of 2nd harmonic as a function of tracking
angle error. At tracking angle errors less than 5 degrees, the 2nd harmonic level is essentially negligible.
I have 21 phono cartridges. I used these cartridges to determine a statistically valid fixed tonearm geometry
so the user is relieved of a complex set-up. All who have used this approach have commented on the ease of
set-up and all have been more than satisfied with the result. Users of Amadeus simply mount the cartridge
on the tonearm and proceed to the music.
