About the Monbrison

The Shindo Monbrison is a beautifully hand-crafted vacuum-tube preamplifier featuring eight tubes including two Telefunken ECL 94S, two 12AU7, two 12AT7, and two 6X4WA. It offers a moving-coil phono stage voiced for the Shindo SPU cartridge and a moving-magnet phono stage compatible with a wide variety of cartridges, switchable via a rear toggle. The preamplifier includes four line inputs labeled CD, FM, TV, and AUX, and one pair of RCA outputs. It is built with hand-picked NOS parts and point-to-point wiring, with no printed circuit boards. The Monbrison is designed with dual-mono architecture for left and right channels, isolated chambers for power supply and signal circuits to minimize noise and crosstalk, and uses custom output transformers to lower output impedance to 600 ohms. It has an expected tube life of over 10,000 hours, ensuring long-term reliability. The chassis is compact and elegantly finished in Shindo's signature green with gold knobs and a front window displaying tubes. The preamplifier is known for its clear, open sound with a very low noise floor, and a frequency response of 20 Hz to 20 kHz. Power consumption is about 50-80W depending on the version, and it operates on AC 120V or 220-240V at 50/60Hz. Dimensions are approximately 350-395 mm wide, 120-165 mm high, and 240-310 mm deep, weighing around 8 kg. The Monbrison is highly regarded for its musicality, build quality, and sonic performance, positioned in Shindo's lineup between the Aurieges and higher-end models like the Petrus III.
