Kinki Studio EX Series M1+ Integrated Amplifier

"The true universal integrated amp, period".

This is the design aim of the new EX-M1+. The answer for many of our customers who were looking for an End Game integrated amp with preamp output, home theater bypass input, fully dimmable display.


The EX-M1+ is designed based on the award-winning EX-M1. The good of the EX-M1 is well-preserved. Advanced microprocessor-controlled, relay-based R-2R steps attenuator, dual 300VA UK made AMPLIMO transformers, quasi monoblocks amplifier stage with EXICON MOSFET lateral, known for its ultra-fast and dynamic sonic response where the EX-M1+ benefited with.


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 you to use the EX-M1+ 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.


The display can now be dimmable, off completely, literally.

We have also improved the internal wiring with pure OCC copper and overly well-made gold plated connector for the line stage input signal and transformer primary stage.


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.
