LP Record Cleaning Machine - Ultrasonic or Vacuum


I am new to analog and am considering to get a record cleaning machine. There are some comments that the ultrasonic may damage fine patterns oinside the tracks of old records and resulting in lost of high frequency extention. Would anyone have any comments or experience on the issue.

Thank you in advance for your responses.

Someone will have to prove to me that a cutter head can cut a more complicated groove into vinyl than a modern cartridge can read, given they are normally cut at the same speed they are played. Have there been any definitive tests on that issue?
