Includes 2 base modules, each with 2 shelves, one tall module with single shelf, and 2 short modules, each with single shelf. All premium upgrades including Special Edition columns with center aluminum tubing and SE polymer fill, Formula carbon fiber/kevlar shelves, and Apex footers. One custom carbon fiber/kevlar 2.25 inch thick turntable shelf is included. Buyer will need to purchase new Sorbothane dampers, based component weights. The system is in excellent condition, although there are scratches on some of the shelves. I have included a copy of a quote on what it it would cost to purchase this system new. The turntable shelf, if available, would add quite a bit to the cost. If the system sells for my asking price, I will pay for shipping.
