I've owned all 3 and still own the Silkworm + with Xhadow rca connectors. They are all very good, and all 3 are really great guys to deal with. The Silkworms just sounded more natural to me in the end, and as noted above had a better presention of low end material in my system. It must be said at this point you are really getting into personal preference and taste, so what yings for someone else may yang for you, or vice versa. All three offer trial periods I believe, it woud be best to listen for yourself.
