My experience has been that a noisy record will remain a noisy record with an RCM, Ultrasonic, or any combo thereof.
I’ve taken problematic samples to my local B&M audio store with an ultrasonic cleaner with detergent bath and air blow dry cycles. Despite multiple attempts at home on my RCM - some records just remained noisy. So I was hopeful that an ultrasonic cleaning would be the answer.
Twice thru and all the ticks and pops were in the exact same spots.
I’ve sent the same problematic samples (8 records) to a company that specializes in multi-step cleaning/archiving services for vinyl LPs. I carefully played and noted surface noise problems before sending and unfortunately, after return, the surface noise remained. Perhaps the sonics were improved a bit, but ultrasonic cleaning will not be a magic cure for ticks and pops.
