Well I for one think that the Benefits far out weigh the negatives. The $40 can of spray is an award winning product that is meant as a tweek. The very subtle details that I might be blanketing are a minor trade off IMO. I keep my stylus clean with a good cleaner and dense brush. I admit If you TREAT your stylus AND use Gruvglide it does dull the sound. Too much treatments..not good. So then you can easily make the leap to say ALL stylus TREATMENTS are no good as well. Do you treat the stylus? or do you treat the record? or both? hmmmm sounds like another thread..lol Happy listening everyone.
