I own the V-8 and it certainly does improve the sound of records. It opens them up considerably. But as I've posted elsewhere, the GEM Dandy Record Cleaner did a considerably better job for a far more significant drop in price. For older and damaged records, I found the Groove Lube to very helpful at reducing the sonic effects of the damage. It does leave some residue on the stylus that can easily be removed, but you have to carefully follow instructions and use as little of the Groove Lube as possible and buff the record carefully after spraying on the pads, rubbing them and applying the treatment.
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?
