I also use the Orea Bordeaux under my table (Garrard 301) I think they have a huge improvement over the cone system I had prior. most notably the isolation of external vibrations, not suspended table isolation mind you. I found they helped focus the detail quite a bit and stabilized the low frequencies allowing for much better bass detail. Over all a great addition to my table. I also use three.
Note they need to be with in the weight range or you will not get the full benefit out of them, this is because they need to be properly pre loaded but not over loaded.
