My ''theory'' (aka ássumption'') is that Ikeda san deed not spend
much money for advertising. This explains the lack of information
about the most of his carts. Thanks to Dertonarm I learned about
FR-7 series but needed to hear all of them in order to decide which
to keep. My comrade Don (Griffiths) and I repeat the same procedure
regarding Ikeda 9 series ; the ''cantileverless kind''. We started with
9 C 2 and 3 and are now ''inspecting'' the REX and SUPREMO.
The big (?) difference between those and the rest is VTF : 1.5 g
versus 2-3 g. Those cantileverless kinds are not good tracker.
On test records by tracking ability one can hardly get 50 microns
''pure''. Our assumption based on this ''theory'' seems to be correct.
Don who already tested (my) REX got 60 microns pure with 2 g
but prefer 1,75 g. sound.
