Dear Dover: +++++ " Another problem I have seen many many times is caused by armboards that are not perfectly level and referenced to the platter " +++++
agree, several times.
Other reasons for the needs on azymuth control/tool: is there cero tolerance in the " flat " cartridge top plate? or cero tolerance in the tonearm headshell plate? or cero tolerance in the tonearm it self alignment: it is dead straigth? and we can go on and on on the subject.
Dertonarm said that in 12 years he did not found out any cartridge with trouble about, he is really lucky!. If we assume that he tested 1 cartridge by day then he tested around 4K cartridges ( or maybe only 600. ) when in those 12 years the cartridge universe was several hundred thousands of cartridges and counting.
Regards and enjoy the music,
