Dear @nandric : With all respect. For me this audio analog forum main target could be that any audiophile with any knowledge level can learn what to do to improve the listen experiences.
Maybe I'm so stupid but I don't know how can help any one to improve its day by day listen experiences to answer your thread question:
"
it is
the groove which determine cantilevet/stylus position .? "
You already answered your self in the OP: silly question. Who cares? curiosity? or really silly question? . You said it not me.
Btw, 37 of 58 posts in the thread came from you. No I don't need you give me any answer to my post. Appreciated.
Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
