So before I subjected my LP collection to a new device such as this, I'd really like to see some electron microscopy on a new LP, and after various numbers of cleaning cycles with the Vortex to determine if the landings or top edge of the groove walls were at all distorted.
Since the stylus normally touches halfway down the groove, what is happening at the surface of the record should not be of much consequence.
