Semi forgot to mention the experiment we conducted at his house several years ago. He told me that he had tried at least 10 - 15 different amp stands under his BAT tube amp. He ended up with a piece of 300 lb slab of stone that he was using under smoe electromicroscope in his lab at work. He had been using that slab ever since I met him.
One day when bunch of us were over, he told us he just spent $$$$ on these new racks (Grand Prix) sitting in the back of the room. We helped him move the slab back and put the GP amp stand in front of the slab. I thought he was going crazy spending that kind of money for stands. Then I left the amp stand up (without the acrylic board) with 1 finger, and thought he was for sure a nut as I was a believer of more mass the better.
We then move the amp forward onto the Grand Prix stand for another round of listening. None of us had heard of this company before. But we definitely heard a big improvement in various areas. We then moved the amp back and forth several times just to confirm.
And it make sense. Several of the guys at that listening work for semiconductor companies, and we've all seen various types of vibration control devices used in labs for vibration sensitive equipment. So it make sense that any mechanical system (LP or CD playback) and tube equipment would benefit from vibration control devices such as a rack.
