We're moving and our beautiful mc7300 must go . This is the coveted narrow chassis version , and comes in its original double shipping carton with wood screw down bottom board and all foam . This one runs dead silent and has balanced and rca inputs . These are known for being very neutral with quicker attack than most other mac's . It sounds glorious as a 300 watt per channel autoformer mac should . I was going to list it as mint but upon very close inspection I did notice a couple extremely small scratches on the top cover and a scratch on the top side edge of the silver side bumper . I tried to capture them in the photos but you may need a magnifying glass to see . This amp will be missed .
