LP Cleaning Machine surprise

I have an older Nitty Gritty machine the last time I used it was a number of years ago.   At the time the difference between a  Nitty Gritty cleaned record and one that was just dust removed before playing was not noticeable.  I suppose my system is now at a different level,  because after cleaning a couple of sides just now, the difference was startling.  The tonality remained as it was before cleaning, but the clarity.....the spaces between the notes, and the instant initiation of instruments made the work very worthwhile.  Recommended.
