FWIW, ultrasonic stylus cleaners are not “ultrasonic”, if you define it as beyond range of hearing. They operate at about 500 Hz.
I once compared US cleaning to cleaning with my VPI HW17, using DI water, alcohol, and TX100 in the VPI. I used a familiar recording by Johnny Hartman. The US machine was on demo at the CAF in DC, and the owner cleaned the LP with his machine at the show. I could hear no significant difference between the two methods, both excellent.
