Marantz MM7025 2 Channel Home Theater Power Amplifier Connect this 2 x 140watt 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 lowfrequency half of your system. Audiophiles using a preamp or AV 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 secondzone power among multiple rooms, don't worry. There's plenty of juice here to go around.
