I'm considering selling this (3 x 200W @8 ohms or 3 x 300W @4 ohms) beast. It was purchased new in 2000 (retail $1650) and I'm the second owner. The newer 2003A version has 12V power up feature, which mine does not. The only reason I would give it an 8 instead of a 9 is due to it's age. What should I ask for it?
