The updates.
I am ,qua outlook, on the side of Schipo but fot the
context I must refer to Raul:'If the design is sound
then why so many updates?'
Rauls context was 'tonearms' and I presupose that he
meant Graham (?).
I mentioned my Audiomeca J1 but not the designer.
Pierre Lurne is an physicist and designed first for
Goldmund (TT, linear tonarm F3,etc) and then for hes
own Audiomeca ( J1,J4,Romeo and last Belladonna).
Lurne has 'strong opinions' about the TT,tonearm,etc
design and emphasise that thy are based on physics.
Acc. to Lurne the platter is the most important part of
an TT,with the bearing as 'included' in the design-
'philosophy'. The most 'correct design' is the inverted
bearing with the 'centre of gravity' in the platter.
This 'centre' is only 'nearly accessible '(see Googel:
Pierre Lurne).
The platter of my Audiomeca (8kgr.) was balanced to an
accuracy of less then 0.5 gr.(BTW I have never seen an
update for Lurnes TT).
If this statements are sound (I am not an Physicist)
then,it seems to me, the design of Linn makes also
some sence.I can't recoll that Linn ever 'modified' or
'updated' the platter. So I think that the 'mystery' of
Linn must be the platter. That is of course an conjecture.
I am sure that there are graduate physicist in our forum
and hope thy will expplain the issue more eloquent.
Cheers
