Testing in a better system is easy—just make a couple of sets and take them over to try in someone else's system that's better than yours. If you're in an audio club you probably know a number of people with better systems.
Unfortunately that's just subjective testing. If you want objective tests, scientific tests, then you need access to the right test equipment such as an accelerometer and you need some sort of standardised test procedure. It would be nice if there were a specified standard for testing the degree of vibration reduction in audio equipment but as far as I know there isn't, which means there's no way of accurately comparing your results to the results of any other product. If you're trying to compare test results, the tests you're comparing need to be conducted under identical conditions and that usually only occurs when there is a specified standard test for the purpose/application you're interested in. Provided you don't need comparability, you could test your turntable with the stock feet and then with your feet but if you want to test how well the feet isolate your turntable from floor/rack/shelf borne vibration you need to find some way of ensuring that the level of vibration reaching the shelf from the floor in each case is identical. That may be difficult. You'll end up with some figures but trying to translate the results into some kind of predictor for effects on the sound of a system is likely to be pretty impossible since there's so much variation in the vibratory environment of different systems due to differences in equipment, floors, etc.
