Lyra Atlas SL Cartridge Magnet type??

That magnets ''sound on their own'' is curious ''argument''. 
But in our hoppy myths are usual and even needed to ''strengthen''
the arguments. The question then is why should any one use
lesser sounding magnets? 

Lukaschek the owner&designer by Benz uses ruby plates
for the coils in order to use stronger magnets. The reason is
''iron core'' by the most MC cartridges with danger of ''saturation''. Iron core is used to increase output. Avoiding ''iron'' means also
more wire for the coils resulting in higher impedance. By LP-S
