I've had three VPI HW-16.5's over the years and now I have a Spin Clean that was given to me for free. I didn't want to think it could ever replace the 16.5, but this thing continues to blow my mind. I have developed a specific technique. When I get a new record (new or second-hand), I clean it, play it a few times, then clean it again, and I would say I almost always notice an improvement after the second cleaning. I'm wondering if using a conical stylus with a tracking force of 3 grams helps loosen dirt and debris from the groove more than, say, a line contact stylus tracking lighter...? Anyway, this weekend I acquired a favorite, rare LP. Before I bought it I had the chance to preview it. My friend, a dealer, said it had been cleaned with a VPI, and he told me I should NOT use a Spin Clean on such a rare and valuable record. On that initial listen, the record sounded decent but I was honestly holding back my enthusiasm until I got home to clean it myself and play it on my rig. After one Spin Clean I would say the surface noise declined by at least 50%, then after a few more plays and a second cleaning, it is now damn near silent in most spots. Just amazing. I've had so much success with this thing in the last couple years that I think I may never go back to a vacuum machine. NOTE: Fans of vacuum cleaning machines, this thread is not intended to start controversy about record cleaning machines or to belittle vacuum machines so please don't take it that way.
