Selling (3) CA-M400 mono blocks. Would consider selling 1 or a pair . Excellent performance in a non-smoking environment. Amps are about 13 years old and in excellent condition. One of the amps have 2 small skuff marks on right side bottom edge not visible when sitting in rack. Will provide photo upon request. Thanks for looking. https://classeaudio.com/ca-m400/
