Kinki Studio EX-M1 Integrated Amp


The EX Series is tuned to reproduce sound quality with balance mid and smooth extension in both ends, high and low extension. The EX-M1 is fully modular, a dual mono design in a single chassis. Rich in tonal quality, details, dynamic, and high resolution. Silky smooth volume control thanks to the MUSES volume control, which is known for its precise and accurate volume adjustment with precision matched resistors.

Crafted To Perfection

Purist. Perfectionist. Minimalist. Call it whatever you like. It was engineered and built to meet the highest quality standards.

Power Stage

The power amplification circuitry is mounted directly on a large custom-made, gold anodized heat sink. The power stage is equipped with two pairs of power EXICON MOSFETs, driven in Class AB. Two identical power stage modules are arranged on the left and right sides of the chassis, deliver impeccable power for the two channels, 215 watts into 4-8 ohms.

High Damping Factor

High damping factor unleash the full potential of the sonic performance of the loudspeakers. EX-M1 employs high power rail supplies, delivering fast and high recovery DC supply to the power stage. The ultra-high slew rate and DC-coupled (no capacitors in the signal path,) yield exceptional acoustic excellence, neutrality, transparency, details, dynamic and ultra-fast transient response.

JRC MUSES 72320 Volume Control

Most amplifiers use a potentiometer for volume control. EX-M1 uses an advanced microprocessor-controlled, JRC MUSES 72320 2-channel electronic volume, which is optimized for high-end audio and professional audio applications with advanced circuitry and layout. The MUSES 72320 performs low noise and low distortion characteristics and with resistance ladder circuit.

215 Watts RMS Into 8Ω

With its 215W (8Ω), both channel driven, The EX-M1 can literally drive anything you throw at it. It is rare to hear an integrated amplifier with such driving capabilities at this price range.

Cost-Is-No-Object Approach

The EX-M1 uses a high cost 0.2µm gold-plated printed circuit board (PCB). Looking at the PCBs, it is clear that the designer is well aware of the limitations on the fine contact area of the general circuit board, specifically increasing the soldered area at each solder joint and adding as much shielding as possible. The EX-M1 uses two 400VA encapsulated transformers, one each for Left and Right channel power supplies. Dual mono power rails do not interfere with each other to improve the channel separation.

Signature Sound Characteristics

Neutrality, musicality, rich tonal quality, vivid sound imaging were the main characteristics we aimed for when designing the EX-M1. An integrated amplifier that can produce an extremely detailed, high resolution and dynamic sound. The choice of components, the design, and tuning achieve just that. That is the Kinki Studio gear’s signature sound.

6moons EX-M1 Integrated Amp – Blue Moon Award

Though the Kinki unmistakably belonged to our generic Swiss school, it included that other Swiss, subtle yet distinctive, Nagra aroma. It derives from their signature obsession with tubes even though in much of their recent gear, they don’t use valves to get there. Without impact on the noise floor to maintain superb magnification powers, it injects a whiff of textural extra and transient ease. I needn’t spell out what that says about the M1’s sell price.

Yours truly considers himself as lucky to be now familiar with it

Subjectively speaking, such a result not only involves this scribe more but lively, direct and agile by nature also boils his blood quicker. That’s what the EX-M1 did exactly, it remarkably well morphed my daily speakers into something they aren’t with most electronics and hearing less venting and more OB alike quality from them I’ve found truly impressive.
