DBT is not always essential in scientific research. What is required in science are controls, both positive and negative. In hifi, all you should really need are some reference points: as an example only, a set of Stillpoints, a set of wooden blocks, compare those with the supports you are testing as well as no vibration support at all. Try it at different times of the day and in a friend's hifi system as well if possible. Trust your ears and enjoy the music.
