A product for the perfectionist
I have used several of the most popular products such as Disc Doctor and Audio Intelligent and I find them to work very well, provided you employ a proper cleaning routine. Re-cleaning records with Vinyl 1 previously cleaned with the others resulted in an audible improvement in the clarity and musicality of the recording. While expensive, it is a one-step product and is therefore priced competetively with high-end multistep products like Walker and Audio Intelligent. I think that Audiotop Vinyl 1 has a valuable place on the perfectionist's shelf. Definitely worth trying at least once.
