Dr. Kirmuss:

I want to share my absolute delight and astonishment with the Ultrasonic Vinyl Restoration System.  This must be a "best buy" for the benefit of ultrasonics to restore LP sonics to their potential.  Over the past five decades I have used many DIY and professional cleaning systems.  Let me jump right to the point, none of those systems have come close to the sonic benefits I am experiencing with this system.  To use an old cliché, it is like opening a window.  This simply is dramatic.  My collection is rather well kept except for some used records that I picked up, but what I now hear from them is a revelation.  This cleaning solution is simple, effective and impactful.  Thank you.

Kind regards
