Marantz Model 30 Integrated Stereo Amplifier

Description   Marantz MODEL 30 Integrated Amplifier Get the most musical sound possible from this beautiful, integrated amplifier. Exquisitely tuned by the Marantz Sound Master, the MODEL 30 integrated amplifier features a master-curated Marantz HDAM and a fully discrete design for luxurious Hi-Fi purity. Designed to last the test of time and make all your music unforgettable. The MODEL 30 Integrated Amplifier Led by meticulous Marantz Sound Masters and an approach to sound passed down through generations of experts, contemporary technical innovation and Hi-Fi tradition are combined to create MODEL 30. The all-analogue design features a fully discrete two-stage build, with independent power supplies for the pre-amplifier and power amplifier. The power supply circuit, designed exclusively for the preamplifier, enables a stable power supply unaffected by fluctuations from power demanded by the power amplifier stage. An oversized toroidal transformer is dedicated exclusively for the preamp to ensure high purity while a double shield steel case is mounted around the transformer to suppress the leakage flux that could generate noise in peripheral circuits. The power supply for the power amplifier stage delivers high current instantaneously to the switching mode amplifier. This ensures maximum control over any connected speakers to follow even the hardest bass attacks and provides clean power for the reproduction of the finest details. The result is absolute signal purity and exceptional audio quality. The amplifier also features a moving coil and moving magnet phono stage—complete with Marantz Musical Premium Phono EQ circuit and Marantz HDAM technology—for top-of-the-line performance. The Phono EQ stage in the MODEL 30 amplifier can be used with both moving magnet and low-output moving coil cartridges, thanks to a built-in MC head amplifier. Distortion is reduced using two-stage amplification in the phono stage, and Marantz HDAMs are combined with JFETs (junction field effect transistors) in the input stage, giving high input impedance. The exclusion of coupling capacitors further simplifies the design, reducing signal distortion and enhancing signal purity. Further, MODEL 30 is equipped with an input impedance selector, which can be adjusted to three different settings “MC Low (33 Ohm), MC MID (100 ohm) and MC HIGH (390 ohm),” which further optimizes sound performance when using a moving coil or magnetic moving cartridge. MODEL 30 continues Marantz’s tradition of using its proprietary discrete circuit design boards—Hyper-Dynamic Amplifier Modules (HDAMs)—to replace chip-based amps and offer the most musical, accurate and detailed sound possible. Leveraging curated discrete surface mount components with short mirror-image left and right signal paths, the HDAMs dramatically outperform regular integrated Op-amps to achieve exceptional sound quality and performance.
