Slappy, sorry if I offended you, but I felt that the main body of your thread was just as offensive. Whether you realize it or not, the majority of your thread body was directed at ridiculing the use of audio racks as a viable product that can help the sound. I understand that perhaps you felt that was being funny. But it was being funny at other's expense. When you set the tone of ridicule, you can expect a similar tone in response.
To answer your questions, the racks will make a difference, either better or worse, depending on how well they do the job of removing the offending vibrations in the system. There is differing opinion on what works best, but most agree that it does work.
