EX-M1

About the EX-M1

The Kinki Studio EX-M1 is a Class AB integrated amplifier designed for audiophiles seeking high power and refined sound quality. It delivers 215 watts RMS per channel into 8 ohms and 400 watts into 4 ohms, with a frequency response of 10Hz to 150kHz (±3dB). The amplifier features an ultra-precise 256-step microprocessor-controlled relay-based R2R volume attenuator using the JRC MUSES72320 controller, allowing fine volume adjustments. It employs two 300VA UK-made AMPLIMO transformers, one for each channel, to minimize interference and improve channel separation. The circuit boards use 0.2µm gold-plated PCB for enhanced signal integrity. The power stage uses EXICON MOSFETs in Class AB mounted on custom gold anodized heat sinks for efficient heat dissipation. The EX-M1 has a high damping factor of 2000, a signal-to-noise ratio greater than 103dB, and total harmonic distortion plus noise (THDN) of 0.0232% (0.006% A-weighted). Inputs include three RCA and one XLR (quasi-balanced), with speaker outputs via 4mm binding posts. The amplifier is built with a minimalist aesthetic, featuring a ribbed anodized aluminum faceplate and two large control knobs for input selection and volume. It weighs 25 kg and measures 430mm wide, 125mm high, and 370mm deep. The EX-M1 is praised for its neutral, transparent sound with rich tonal quality, excellent imaging, and dynamic range, offering performance comparable to much more expensive amplifiers at a price around . It is made in China with meticulous attention to detail and quality components, representing outstanding value in the high-end audio market.
