Obviously isolation can be hit or miss but can almost always help once you find the right type. You can shoot the lights out and pay up for something like a Townshend Seismic product and almost certainly get a significant improvement, but it comes at a price. Alternatively you could just try something like this on the cheap and see if it works and if not just return it to Amazon, so why not? Several people here have used these to good effect. Just a couple thoughts to ponder, and congrats on the excellent new ‘table!
