For Yogiboy: 'needletalk' is the direct physical noise the needle/LP interface gives off when playing a record.
It is a purely physical thing. The needle in the groove vibrates, and makes noise. You can actually hear the music directly from the needle/vinyl interface when the system is in motion.
ALL stylus/LP interfaces when the LP is in motion and the stylus is in the groove make this noise. Just some do it much louder than otheers... but they all do it.
