The technical argument is like stating that old lathes are not
as good as the new CNN lathes. But the work done is dependant
from the (master) mechanics. My Sumiko 800 is designed by
engineer Fletcher but each of the 150 parts are hand made on
a lathe by the master mechanics Demian Davidson. Breuer also
make his arms by himself. J.Carr and Ikeda both still use the old
Ikeda's master machinist. We also know that those ''tubed''
cantilevers from the 80is are made with laser. But despite the
possible ''evolution'' of lasers we don't see such cantilevers any
more.
If one compare, say, Micro Max 282 with whatever new tonearm
one would not conclude that the technology is more advanced
at present.
