The MM7025 is a stereo power amplifier by Marantz that delivers 140 watts x 2. It was released in 2010. It is a 2-channel design using a Class A/B output stage. Speakers connect via binding posts. The Marantz MM7025 has an MSRP of $1,000.
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Marantz MM7025 is rated at 140 watts RMS into 8-ohms. Marantz provides this wattage at a THD (Total Harmonic Distortion) of 0.08% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 140 watts into 8-ohms (20 Hz-20 kHz) at 0.08%
- 105dB Signal to Noise Ratio

Need more power?
Marantz MM7025 is rated at 140 watts into 8 ohms, which puts it in our 121 to 180 watts band. The next band up is Over 180 watts, which is worth about 2.3dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room. Plenty of systems are better served by the 91 to 120 watts band and better speakers.
When pairing the Marantz MM7025 with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.

Marantz MM7025 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓140 watts per channel into 8 ohms.
- ✓Signal-to-noise ratio of 105dB, so the amplifier itself should be inaudible between tracks.
- ✓Detachable mains lead (IEC 2-prong).
- ✗A power amplifier has no volume control and no input selection - it needs a preamplifier, or a source with a variable output, in front of it.
