and our demanding love of it. SM-11S1 Stereo Power Amplifier Many early Marantz power amplifiers produced comparatively modest power. In that light, the SM-11S1 - with its 110 watt per channel power rating - holds to this tradition. But Marantz tradition also mandates innovation. And so the SM-11S1's output doubles to 220 continuous watts per channel when delivering power to low impedance speakers. A "bridging" circuit lets you configure the SM-11S1 as a monaural amplifier delivering 420 watts. In any mode, the SM-11S1 generates truly exceptional control and delineation of the most complex sources. But brute force without finesse serves no real purpose for the sonically sophisticated. To that end, Marantz engineered many new techniques. At the circuit board level, precise signal path positioning minimizes channel interference for superior ambience reproduction and soundstaging. The SM-11S1 also boasts the newest SA3 version of Marantz's Hyper Dynamic Amplifier Module (HDAM®) technology so it instantaneously responds to any signal. And the SM-11S1, as do all Marantz Reference components, resists the kind of destructive interaction with loudspeakers that can degrade audible performance. The high-current power supply boasts a toroidal transformer fully as large as that used in our flagship MA-9S2 monaural power amplifier. Configured for stereo use, this transformer feeds innovative power supply circuits that allow the SM-11S1 to perform optimally under even the most demanding conditions. Of course, the SM-11S1's high quality parts - even the precision WBT speaker cable terminals - were chosen only after extensive listening tests to determine their positive contributions to overall sound quality. The SM-11S1 benefits from more easily observed qualities also. It accepts balanced XLR inputs and easily switches between stereo and bridged-mono modes. A remote power turn-on circuit lets you activate the amplifier from a preamplifier or surround processor. And the front panel digital power meter monitors output with magnetic sensors that do not interfere with the audio signal. The subtly-curved front panel echoes the SM-11S1's internal sophistication with a substantial yet décor-conscious design equally at home in a custom cabinet or on an open shelf. Performance. Design. Appearance. The SM-11S1 is a Reference in every way. "Music is what feelings sound like." - Author Unknown 7
