Yes, I have the SP-6 Model Sistrium Rack and is very pleased with the performance of the the stand and its' effect on my system's overall sonic presentation. Excellent at reducing vibrational noise, presents a balanced focused image, that is locked in. However, the rack does not confine your components, but enables them to perform with a black background with micro and macro details heard. I would also recommend the Micro-Bearings as a filler for the three rods.
