This is a pair of Classé Ca M600 Mono Amplifiers once used for the main speakers of my fathers very expensive high end Surround-Setup. As my father passed away, these were shipped from his apartment in Boston to his hometown Wuerzburg in Germany. Unfortunately, they only work with 120V American and not the European 240V power grid. I was able to test with a friend who is an electrical engineer using a converting device and they worked just fine. However, this is no permanent solution and so Im trying to sell them back into the states :)General condition is pretty good. My friend and I had them open and cleaned from dust from the inside. On the black Aluminium top there are some minor scratches and marks because the two units were standing on top of each other.Dimensions per unit are 44,5 x 44,5 x 22,5cm / 17,5 x 17,5 x 8,8 inches. Weight 40kg / 88 pounds each. The amplifiers have outputs for bi-wiring.Shipping cost into the states is around 800€-1200€ based on a quick online search. If we agree on a deal, we can look for the best offer. New product price was about 14000$. The last picture is an estimation done by a hifi dealer. Note: Although I tested them, I can give no warranty for the units since I am not a professional dealer.
