Watch this YouTube video from Dynaudio. It's got some interesting info in it. You have great equipment, although, if I had your equipment, I'd choose a speaker from Focal, Von Schweikert, B&W, Wilson, etc. Some bookshelf Dynaudio speakers would go well with your line stage and amp set up like the Special 40 or Heritage Special. Go listen to them at a brick and mortar store.
