There are sample before and after cleaning with the Disco Antistat machine, from Knosti. For testing purposes, I cleaned a series of 5 records using their liquid. All records were bought from second hand market, and despite previous attempt to clean them, were probably dirty, dusty and in any case so did not sound that good. The first samples are from records that shows also wears and scratches, as the last ones were much clean visually. That give us a good range of situation and appreciate the impact of that machine.
