Marantz MM7025 power amplifier

Connect this 2 x 140-watt beast to the preamp outputs of a receiver or a wireless music player such as the Sonos Port. Add a pair of speakers that can handle the high power, and get ready for a breathtaking sonic thrill ride.
Use the MM7025 in your main listening room to drive your primary speakers. Expect to hear tighter, weightier bass, and wider dynamic swings that bring you closer to the sound of live music. (If your speakers can be biamped, this Marantz makes a superb choice for driving the low-frequency half of your system.)
Audiophiles using a preamp or A/V processor with XLR outputs can connect to this amp's XLR inputs and take advantage of the superior sound quality they provide. You could also use this amp to power a second zone. If you're using a speaker selector to divide the second-zone power among multiple rooms, don't worry. There's plenty of juice here to go around.
The MM7025's current-feedback amplifier design provides for nuanced reproduction of fine musical detail and plenty of sonic muscle to support chest-thumping transient peaks. HDAM-SA3 circuits provide high-speed signal response for precise sound.
