140 Watt x 2-Channel Power Amplifier
The Marantz MM7025 Stereo Power Amplifier answers many needs for both two-channel devotees and home theater enthusiasts alike. It produces 140 watts of full-bandwidth, very low distortion power per channel, so it can precisely control demanding speakers in large rooms or deliver subtle nuance in smaller acoustic environments.
 
The MM7025’s advanced technology serves all your listening needs. Current feedback circuits, originally developed for the Marantz’s Reference Series amps, insure the purest sonic reproduction regardless of source. In the final amplification stage, specially selected LAPT Hyper-Power output transistors, also borrowed from the Reference Series, deliver fortissimo and pianissimo passages with equal aplomb.
 
The MM7025’s heavy duty, gold-plated, four-way binding posts accept virtually any choice of loudspeaker cable The amplifier is less than 14” deep from front panel to rear speaker terminals. This lets you place the MM7025 almost anywhere – in a cabinet or on a shelf. Selectable single-ended and balanced inputs assure easy connectivity in any system. This is Marantz quality at its best.
