The Simaudio Moon 340i is a stereo integrated amplifier designed for audiophiles seeking both power and flexibility. It delivers 100 watts per channel into 8 ohms and 200 watts into 4 ohms, operating in Class A for the first 5 watts to ensure high fidelity. The amplifier includes four single-ended RCA inputs, one optional balanced XLR input, and a front 1/8" mini-jack input for portable devices. It offers an optional internal digital-to-analog converter (DAC) supporting USB, S/PDIF, and TosLink inputs with high-resolution audio up to 32-bit/384kHz and DSD256. Additionally, an optional internal RIAA phono preamplifier supports both moving magnet and moving coil cartridges. The Moon 340i features a robust 400VA toroidal transformer and 40,000µF power supply capacitance, bipolar output devices, and a damping factor greater than 200 for precise speaker control. Connectivity includes tape outputs, preamplifier outputs, headphone output (1/4" TRS), RS-232, IR ports, 12V trigger, and SimLink for component communication. The unit weighs approximately 13-15 kg and measures about 429mm wide, 89mm high, and 376mm deep. It is built to high standards with a ten-year warranty on electronic components and three years on moving parts. The 340i is praised for its transparent, smooth, and powerful sound, making it suitable as a centerpiece for high-end home audio systems.
