@nandric : You are wrong again and talk because you have " mouth ". I never posted if the EPA 100 is better but only about its overall design made not by a single person but for a company that in those times belongs to the japanese gigantic Matushita group where Panasonic belongs too.
You can be sure that no one has more resources, dedicated and experts engineers, quality level of design and excecution of designs that TECHNICS.
In those times Technics never did a single design mistake in all its analog audio items. Technics manufactured TT motors for companies as Micro Seiki and others, his SP-02 was designed expressily to use as a motor for the recording cutting machines and even the SP10 MK3 motors were used in those cutting machines. You have no idea what you are talking about. With all respect to Ikeda and Reed you named they are almost " nothing " against what was Technics in those times: a " brutal " corporation.
There is no single problem with heavier counterweigths in the EPA 100, Technics gaves it as an add-on for those customers that need it. The tonearm bearing desing is unique gimbal kind using 20 precision ruby balls ( Technics precission not other manufacturer level. ). Got it? period.
