Ok, I just got an E-mail from Clarity Cables and Melissa told me that ones that were made out wood were a lot better! They have two models, the 3D Max has 8 outlets, 4 on each circuit.This allows for seperation of source and amp,if desired. The regular 3D has 6 outlets and one circuit. The MAX is definately the better unit! The Max is pretty big too 18X17X8. They only make wood cabinets for the regular 3D model right now and it will be a while before they start making the wood cabinets for the 3D MAX. A speaker company called Escalante speakers is making the cabinets for Clarity Cable. The price for the regular 3D in a wood cabinet is $1900 and 3D MAX in a (granite) cabinet is $3800.
