The part of the headshell on which the cart is fastened I call
''insert peace''. Those can be ordered as separates. This means
as many headshells as one wants. One can even pre-adjust
carts (eff. length) on them for fast exchange. Arche is actually
a frame in which the parts can be screwed with precision screws
and Allen keys. The insert piece need to rotate because of the
SRA provision and is fastened with two steel axes with steel balls
and (tension) springs. That is why flexible headshell wire is
needed. The best quality clips are also needed because the
same wire will be used for all insert peaces . Those made
by Clearaudio are the best. Clearaudio silver headshell wire
are expensive but the best for Arche.
