The Marantz MODEL 30 is designed to deliver a pure analog listening experience by combining advanced engineering with decades of Marantz audio expertise. Its fully discrete two-stage architecture isolates the preamplifier and power amplifier sections, reducing interference while preserving signal integrity from input to output. Custom HDAM-SA3 modules replace conventional integrated circuits, providing faster response, wider bandwidth, and exceptional musical transparency.

Delivering 100 watts per channel into 8 ohms and 200 watts into 4 ohms, the MODEL 30 offers ample power for a wide range of premium loudspeakers. Its high-performance switching amplifier and shielded toroidal transformer provide excellent efficiency, low distortion, and precise speaker control, resulting in effortless dynamics, deep bass, and an expansive soundstage even during demanding musical passages.

Designed exclusively for serious music listening, the MODEL 30 features an audiophile-grade MM/MC phono stage that allows direct connection of high-quality turntables without requiring an external phono preamplifier. Additional analog inputs, Power Amp In connectivity, and high-quality preamp outputs provide excellent flexibility for integrating the amplifier into larger two-channel or home entertainment systems. Source Direct mode further shortens the signal path for the purest possible playback.

Combining luxurious craftsmanship, innovative analog engineering, and the unmistakable Marantz sound signature, the MODEL 30 stands as one of the company's finest integrated amplifiers. It offers the refinement, authority, and musical realism expected from a true reference component, making it an exceptional choice for discerning audiophiles building a no-compromise stereo system.
