MARANTZ MZ-MM7025 Power Amplifier 2 x 140W First Impressions If you’re impressed by elegantly restrained industrial design, the MM7025 is guaranteed to make a lasting – and very positive – impression. The subtly curved aluminum/glass resin front panel adds a sophisticated touch that complements any décor. The central porthole display reflects iconic Marantz designs of the past while it brings you an “at a glace” view of the amplifier’s operating status.
