I've listened to the BAT VK-500 (SS) on Dynaudio's at a dealer and I own the VK-500. I thought it did a great job at opening up these speakers (Confidence 5 and 3 and Contour 3.0) without losing "musicality" or giving any sense of stain at volume peaks. I am definately biased though, being an owner.
