Im selling my beloved NAD Masters Series M25 7-channel power amplifier because Im downsizing my system. Its one of the best amps NAD ever made. Its THX Ultra2-certified, meaning it passes the most stringent of tests by THX. If you know this amp, you know they rarely come up for sale. Please note that 1 of the 8 small blue lights has dimmed. All of the small red lights are still bright. These lights have nothing to do with the sound of the amp. In March of 2022 I had the power button fixed, and also had new caps etc done at the same time. So this amp is in excellent condition and it sounds just as it should. Comes with original box and packing materials. If you have any questions, please let me know! Its also for sale online locally, so I reserve the right to cancel this listing at any time if it should sell locally to someone here in LA first.
