YES. US cleaning will not magically repair damaged discs, but will likely make the sonic damage less audible.
I previously used a Spin Clean and Nitty Gritty---essentially a 2 step version of the VPI process. I was mostly happy with my results. Then I spent time to research US theory, process and application.
Purchased a DIY US kit. Chinese tank, Vinyl Stacker, Rushton's formula.
My results are much better. Surfaces (including from previously cleaned LPs) are more quiet. I hear better reproduction of transients and ambiance cues- the the small and subtle sounds that can be buried underneath even moderate surface noise.
Before US cleaning, I still heard a low level shhhhhhh-wooosh sound on many LPs. After US, just about all gone. My take is that a microscopic layer of debris becomes bonded to the LP surface over time. The layer is thick enough to blunt transients and cover the very low level background cues in the mix. US cleaning removes this layer, uncovering all that is in the groove to hear.
My cost was about $500. New Kirmuss machine is about $8-900 and is a self contained box. Other one box solutions are more expensive.
