I've found the best way, albeit long and drawn out, taking days, is to suck it and see. Trial and error. I try not to take much notice of measurements with testing equipment. The best thing you can use is your ears and tune your tt to your ears, what's best for your personal listening experience. I have just fitted three rubber mounts under the acrylic ring, which has worked wonders. My best listening exoerience to date. There is still a bit Microphony from the chassis, but nowhere near to what it was, but I have virtually no surface noise from the record, at sensible listening levels, even between tracks...I've changed the granite isloation platform for 10mm thick toughened glass..supported on half squash balls, filled with silicone and lead shot..which will shortly be replaced with Vibrapods. My pal Vince is using them and I was there today listening to his rig and it is outstanding.. The Vibrapods are the best isolation feet I have heard to date, without having to spend an absolute fortune..and at just under 22 quid a set are brilliant. If you decide to try these, You'll need to check out the weight of your gear, as there's 4 or 5 different models
