Mlbattey, I have mine on a marble block, but I added Black Diamond cones on top of the marble, and topped it with a their pure carbon graphite "shelf". I also have a concrete slab plus carpet, but my stands terminate in spikes through the carpet. I would still be concerned that your Bryston anchor does not defeat all of the vibration that can ascend the stand anyway. Vibration is pernicous and follows any available path. But if you are following the above, my TT is so flawed in design that all countermeasures are mere band-aids on the real problem.
