Neil will come and give you the low down before long. One consideration is that the size of the cavitation bubble that forms (as well as it's energy) is related to the frequency of ultrasonic vibration. 120kHz bubbles are likely to clean the bottom of a vinyl microgroove, whereas I believe 40kHz might not do such a thorough job in theory. Does that make a practical/audible difference? There's the rub, as there's a lot of money to be saved with a 40kHz machine. I have a MkI Degritter and I'm completely satisfied with it, used after a vacuum clean on a Loricraft.
Ultrasonic Record Cleaner 40 v 80 v 120 kHz
I’m new to vinyl. My table is George Merrill’s Signature Polytable. Most of the records are purchased used from local shops, which range from poor to decent condition. Hence, I need a record cleaner.
I have been researching ultrasonic (US) cleaners online, The standard US cleaners are 40 kHz. More recently, however, I’ve seen companies like Cleaner Vinyl and Degritter are offering multi kHz machines that operate at 40, 80, and 120 kHz.
Is there any evidence that the higher frequencies make a real audible difference? Or is alleged benefits just marketing hype? Any real world feedback if the higher frequencies really improve cleaning would be appreciated.
Thanks much.
