The Marantz SR5004P Surround Receiver is anything but conventional. Of course, it's highly flexible. And thoroughly up-to-date. So it can function as a switching center for sophisticated home A/V systems, including yours. There's video scaling, Bluetooth capability, high power, support for the latest surround formats, outputs for 10 (yes, 10!) speakers, and easy system integration. When you combine that with Marantz's vaunted sound quality, you've got a receiver that redefines enjoyment. Were you expecting anything less? From Marantz? No way. Consider the SR5004P's seven-channel "in-line" amplifier. In addition to its voltage feedback configuration, the SR5004P's amp benefits from selected audiophile-grade components chosen only after carefully designed comparative listening tests. A substantial low-noise power supply based on an oversized EI-core transformer and low-ESR capacitors assure instantaneous current delivery for undistorted peak reproduction. Marantz engineers designed a totally separate audio circuit board to isolate sonics from the spurious radiation developed by video processors. Power is a substantial 90 watts/channel so you'll enjoy dynamic reproduction of both music and soundtracks – all with the clarity that has long distinguished Marantz.
