The EX-M1+ from Kinki Studio is presented as an enhanced, flagship version of the already well-regarded EX-M1. It combines flagship-class performance with practical features tailored for serious audio setups.
THE GOOD OF EX-M1 · PRESERVED
Building on the award-winning EX-M1, the EX-M1+ carries forward everything that made its predecessor exceptional. It features an advanced microprocessor-controlled design, a MUSE volume control, and dual 400VA encapsulated transformers.
The quasi-monoblock amplifier stage with EXICON lateral MOSFETs further elevates its performance, delivering the ultra-fast, dynamic sonic response for which KINKI STUDIO is renowned.
THE GOOD OF EX-M1
JRC MUSES 72320 Volume Control
Unlike most amplifiers that rely on traditional potentiometers, the EX-M1 employs the JRC MUSES72320, a microprocessor-controlled 2-channel electronic volume control.
Resistance ladder design for ultra-precise adjustment
Low noise & low distortion architecture
Optimized for high-end & professional audio applications
Ensures accuracy, transparency, and musicality at every listening level
PERFORMANCE OVER COST
Quality & Performance Over Cost
The EX-M1 is a cost-no-object design, prioritizing performance at every stage:
0.2µm gold-plated PCB for maximum conductivity and reliability
Enlarged solder joints and enhanced shielding to minimize interference
Dual 400VA encapsulated transformers (one per channel) for true dual-mono power
Superior channel separation and stability across demanding speaker loads
Every element reflects the mindset of a purist, perfectionist, and minimalist, built to the highest standard of excellence.
Similarly, HT Bypass can be activated at the press of a button, bypassing the preamp stage so the EX-M1+ functions purely as a high-performance power amplifier.
Similarly, the HT Bypass Input can be activated with a single press of the button on the Remote Control Unit, allowing the preamp stage to be bypassed and the EX-M1+ to function as a power amp.
HIGH DAMPING MODULAR POWER STAGE
High-Damping Modular Power Stage
Power amplification is achieved with precision-engineered circuitry mounted on a custom gold-anodized heat sink for superior cooling.
Two pairs of EXICON MOSFETs, driven in Class AB
Dual modular power stages, left and right mounted
Output: 215W RMS into 4–8Ω
High damping factor for absolute speaker control
Ultra-high slew rate & DC-coupled design (no capacitors in the signal path)
Fast transient response, neutrality, and transparent sound reproduction
CRAFTED TO PERFECTION
The EX-M1 delivers a commanding 215W RMS per channel (8Ω), making it one of the few integrated amplifiers in its class capable of driving even the most demanding loudspeakers with authority.
Its sonic character is defined by:
Neutrality & musicality
Rich tonal quality
Vivid imaging & spatial accuracy
Exceptional detail, high resolution, and dynamic range
Careful component selection, thoughtful design, and meticulous tuning give the EX-M1 its distinctive KINKI STUDIO signature—an amplifier crafted to reveal the truth in every note.
