"The true universal integrated amp, period".
The EX-M1+ from KINKI STUDIO is the ultimate universal integrated amplifier, without question. Positioned as the flagship model above the highly acclaimed EX-M1, it boasts a range of sought-after features including a dimmable display, preamp output, and home theater bypass.
THE GOOD OF EX-M1 · PRESERVED
Drawing inspiration from the award-winning EX-M1, the EX-M1+ retains all the positive aspects of its predecessor. It boasts an advanced microprocessor-controlled design, as well as a MUSE volume control and dual 400VA encapsulated transformers.
The quasi-monoblock amplifier stage with EXICON MOSFET lateral is another feature that enhances the EX-M1+'s already outstanding sound quality, renowned for its ultra-fast and dynamic sonic response.
PREAMP OUT · HT BYPASS
The EX-M1+ offers highly anticipated features such as Preamp Output and HT Bypass, but with a unique twist. The Preamp Output can be conveniently enabled or disabled using the redesigned Remote Control Unit.
This feature enables the EX-M1+ to function as a standalone preamp, or an integrated amp where the preamp output can be connected to a subwoofer or our monoblocks EX-B7 for bi-amping loudspeakers.
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
The power amplification circuitry of the device is directly mounted on a custom-made, gold anodized heat sink, providing efficient heat dissipation. The power stage features two pairs of power EXICON MOSFETs, which are driven in Class AB to ensure optimal performance.
The device features two identical power stage modules that are arranged on the left and right sides of the chassis. These modules deliver exceptional power to the two channels, providing 215 watts into 4-8 ohms, ensuring reliable and high-quality audio performance.
The EX-M1+ is designed with a high damping factor, which allows for the full potential of the loudspeakers to be unleashed and for optimal sonic performance. The device features high power rail supplies that deliver fast and high recovery DC supply to the power stage, contributing to the overall high-quality audio performance.
The device is also designed with an ultra-high slew rate and is DC-coupled, meaning that there are no capacitors in the signal path. This design feature results in exceptional acoustic performance, with neutral, transparent sound quality, exceptional detail, dynamic range, and ultra-fast transient response.
CRAFTED TO PERFECTION
The EX-M1+ boasts an impressive 215 watts RMS power output into 8 ohms, making it one of the few integrated amplifiers in its price range capable of such driving capability. With both channels driven, it can easily power any type of loudspeaker.
The sound signature of the EX-M1+ is characterized by a focus on neutrality and musicality, with the goal of achieving rich tonal quality, vivid sound imaging, exceptional detail, high resolution, and dynamic range. These sonic characteristics are the result of careful component selection, thoughtful design, and meticulous tuning, resulting in the distinctive sound signature that is a hallmark of KINKI STUDIO.
