My first record cleaning machine was KAB's version of the Nitty Gritty. When my friend bought a Keith Monks machine he gave me (!) his VPI 16.5. I have cleaned records using all three of these and have found that when used properly there is no difference in sound between them. All produced clean, quiet records. If you purchase a lot of cruddy used vinyl, an ultrasonic unit just might be better. The more money you spend, the more the machine will do for you.
if I buy an ultrasonic cleaner for my records will I be able to hear the difference?
I have a lot of records and have cleaned some of them with a VPI vacuum machine. My system is quite nice but not ultra high end ( turntable about $2K and the rest to match) .Will I be able to hear the difference , with my system or is it just for those who can afford the very best?
