I've owned many different rcm throughout the years. I currently have access and used my friends' Degritter II w/latest fluid and it makes my lps sound much better and quieter. It comes at a cost but I think it's a worthwhile purchase especially if you can find a good price..
HumminGuru vs.Degritter
I own the original HumminGuru record cleaning machine (not the upgraded model.). I’m thinking of buying the Degritter. Can anyone who owns both machines tell me if it’s worth the greater price? Or, can you recommend a machine in the same price range as the Gegritter that’s better?
