The Kinki Studio - EX-M1+ - the good of the X-M1 preserved
The EX-M1+ is designed based on the award-winning EX-M1. The good of the EX-M1 is well-preserved. Advanced microprocessor-controlled, MUSE volume control, dual 400VA encapsulated transformers, quasi monoblocks amplifier stage with EXICON MOSFET lateral, known for its ultra-fast and dynamic sonic response where the EX-M1+ benefited with.
PREAMP OUT · HT BYPASS
EX-M1+ is equipped with the most anticipated features - Preamp Output and HT Bypass. We did it differently though. The Preamp Output can be enabled/disabled by the completely redesigned Remote Control Unit. It allows the EX-M1+ to be used as a preamp only, or integrated amp where the preamp output can be connected to the subwoofer or to our monoblocks EX-B7 to biamp the loudspeakers.
The same goes to HT Bypass Input. A single press on the Remote Control Unit button enables the HT Bypass Input. The preamp stage is bypassed, EX-M1+ functions as a power amp.
POWER STAGE
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 8 ohms, 400 watts into 4 ohms.
High damping factor
High damping factor unleashes 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.
WHAT'S MORE?
The display can now be dimmed, turned off completely.
We have also improved the internal wiring with pure OCC copper and overly well-made gold plated high current connector for the line stage input signal and transformer primary stage.
SOUND CHARACTERISTIC
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.

Preamp Matching
Our amplifiers are Direct-DC-Coupled without any capacitors in the signal path. This yields less colouration, high resolution, fast, and transparent sound quality.
Should you wish to use other preamp make, please be informed that we do not recommend the use of tube-based preamp.
You may experience slight pops/clicks noise to the loudspeakers, it's likely caused by the DC-offset in the preamp.
