Kinki Studio EX M1 - Audiophile Integrated Amplifier
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, of which known for its precise and accurate volume adjustment with precision matched resistors.
RC MUSES 72320 VOL CONTROL
Most amplifiers use a potentiometer for volume control. EX-M1 uses an advanced microprocessor-controlled, JRC MUSES72320 2-channel electronic volume, which is optimized for high-end audio and professional audio applications with advanced circuitry and layout. The MUSES72320 performs low noise and low distortion characteristics and with resistance ladder circuit.
The EX-M1 uses extremely high cost 0.2µm gold-plated printed circuit board (PCB). From the perspective of 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.
It uses two 400VA encapsulated transformers, one each for Left and Right channel power supplies. Dual mono power rails does not interfere with each other to improve the channel separation.
The power amplification circuitry are mounted directly on a large customs made, gold anodized heat sink. The power stage 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 employes 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), yielded exceptionally acoustic excellent - neutral, transparency, details, dynamic and ultra fast transient response.
215Watts RMS into 8Ω
EX-M1 is one of the rare Integrated Amplifier that is able to provide such a good driving capability in its price range. 215W (8Ω), both channel driven, can literally drive anything you throw at it.
Neutrality and musicality were the goals to achieve. Rich tonal quality, vivid sound imaging, details, high resolution and dynamic. The choice of the components, design, and tuning does just that.
It is the Kinki Studio gears' sound signature.
