I was reminded of the massive differences of opinion by a few things this month.
Roy Gregory blogging on his gy8.eu blog about record cleaning and his link to the ‘bible’ of record cleaning https://thevinylpress.com/precision-aqueous-cleaning-of-vinyl-records-3rd-edition/.
David Vivian conducted a group test of Record Cleaning Machines in the latest HiFi Choice. He reckons it was more difficult to complete than the normal amplifier or loudspeaker group test.
