Connect this 2 x 140-watt beast to the preamp outputs of a receiver or a wireless music player such as the the Sonos ZP90. 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.)
