I too do a version of the Loricraft/AIVS regimen; there's no question it can do a great job and it is time consuming. You can never clean the same record twice so I'm a tad skeptical of listening tests, but I'd be interested to learn your findings. I suppose the bottom line is whether the Audio Desk can replace a vacuum-based machine. Two questions: How many records will the AD do before needing service and when will full service for it be available in the US?
Aluminum Foil test for Audio Desk Vinyl Cleaner
I came accross this Aluminum Foil Test in You tube to check the purported cavitation power of ultrasonic cleaners. A positive test should create holes or perforations in the foil after an adequate period of ultrasonic exposure. ((varies from 40 sec to a few minutes))
I tested my Audio Desk Systeme Vinyl Cleaner but failed the aluminum foil test.
How reliable is this test? The other question is how can I check that my cleaner is doing its job (refering to its ultrasonic property) in a more objective way.?
