It is a class A\/B integrated amplifier and nothing else, making 70 watts per channel into 8 ohms and 100 into 4. Black or silver-gold.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eYou get six analog inputs, one of them a moving-magnet phono stage. Also a record output, a full preamplifier output, a mono subwoofer output and a power amp direct input that skips the preamp section entirely.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:1.05em;margin:0.9em 0 0.25em 0;font-weight:600;\"\u003eFour Binding Posts and a Headphone Jack\u003c\/h3\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eTwo pairs of Marantz SPKT-1+ terminals let you run A, B or both from the front panel. The quarter-inch headphone output is on the front, next to the porthole display, the source selector and the bass, treble and balance knobs.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eA detachable power cable and the RC003PMND system remote are in the box, and the amplifier will control a matching Marantz disc player. It measures 442 by 431 by 130mm and weighs 14.2 kilograms.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eCurrent Feedback, a Toroidal Transformer, and No Digital Noise to Chase\u003c\/h2\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eLeaving digital circuitry out removes a whole category of interference before it starts. What remains is a current-feedback topology, HDAM SA2 and SA3 discrete modules in place of integrated circuits, a toroidal transformer, symmetric board layout and a triple-layer bottom plate.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eFrequency response is 5Hz to 100kHz within 3dB. Distortion is 0.02% across the audio band into 8 ohms, and the damping factor is 100 or better. Line inputs measure 116dB signal-to-noise, and the power amp input reaches 125dB.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:1.05em;margin:0.9em 0 0.25em 0;font-weight:600;\"\u003eThe Phono Stage in Numbers\u003c\/h3\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eMarantz Musical Phono EQ takes moving magnet at 1.4mV into 47 kilohms, tolerates 80mV before clipping, tracks RIAA within half a decibel and returns 87dB signal-to-noise. Bass and treble each swing 10dB, and Source Direct takes them out of circuit.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe amplifier draws 220 watts in use and 0.3 watts in standby, and shuts itself down when left idle. Volume is a linear control rather than a stepped one, and the OLED porthole display dims to suit the room.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eWhat Reviewers Are Saying\u003c\/h2\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eReviewing it for \u003cem\u003eSoundStage!
