''esoteric'' and other retip kinds. My Koetsu rosewood signature
was ''refurbished'' by Koetsu for 2000 euro. My Koetsu Blue Sky
which needed only a new stylus got an boron/Shibata combo
by Axel for 500 euro. My Allaerts MC 2 got a new ''Paratrace''
stylus (only) for 180 GBP by Expert stylus. uk . I felt stupid by
the first two and smart by the last one. A kind of Raul's ''learning
curve''.
