I bought one recently on a whim . I was not prepared for a major improvement nor did I get one . What I did get however was a noticeable improvement in a few key areas of musical reproduction : Dimensionality , musicality and an overall sense that any previous molecules of glare were gone . The real treat however is when it is used in conjunction with a demagnetizer . The cumulative effect is good... not great however . Great is the effect achieved when you first treat the disc with an excellent cd treatment like Brian's Liquid Resolutions cd treatment , then the demag then the dryer : Together the effect borders on excellent.
I am an audio dealer but not affiliated with Brian in any way
