Vinyl for me is a secondary medium. I only have about 20 albums and don’t anticipate obtaining many more. I pay a guy who has a ultrasonic machine who charges $5/lp and also provides a new MoFi sleeve. These recordings shouldn’t require a second cleaning. Once should remove the deepest crud and normal lp care afterwards should suffice.
If I had several hundred albums I would investigate this product, but at present I don’t wish to accumulate another piece of machinery that will leave my heirs groaning with distress.
Yes, the before and after is very impressive. I would estimate a 75% noise reduction
