Well the curious thing is that Japanese economy was based
on replica of European and American , say, inventions. Curious
in the sense that they (aka Ikeda) ask + $ 2000 for the original
B-60 while the most buyers want ''original'' parts by each item.
The obvious assumption being that ''original'' is somehow better
than replica. However the same Japanese have proven the other
way round. This may be different for paintings and antiques by
which ''original'' means (much) more money.
We are discussing the ''mechanics'' of the tonearms while the
function of this B-60 is to move the arm up and down + provide
extra mass for the 'energy transfer''. Some tonearms use huge
nuts for the same purpose. The thing is not supposed to ''sound''
so I can't answer this question. What I can say is that the thing
function as it should and because made from the same ''substance''
(aka steel) is, I assume, as heavy as the original.
The seller told me about his ''profit'' so I decided to buy two
samples. A German friend already offered 700 euro for one of
my samples. I wish I was as ''smart'' with my shares (grin).
@chakster you are always right with your pictures but, alas, not
always with your assumptions. This means that the B-60 on
your picture is the replica. I don' t use the expression ''fake''
because I am a lawyer (grin).
