STEREO POWER AMP
The EX Series has been finely tuned to achieve balanced mid-range and smooth extensions at both the high and low ends, resulting in exceptional sound quality. The EX-M7 is the newest addition to this line-up of Stereo Power Amps.
With dual encapsulated 400VA Toroidal Transformers, 2 pairs of EXICON Laterals MOSFET, and a large power reservoir capacitors bank, the EX-M7 is an upgraded version of the award-winning EX-M1 in stereo power amp form.
Despite these enhancements, the EX-M7 still maintains the superb tonal quality, detail, dynamics, and high resolution that made the EX-M1 so popular.
DESIGNED for CRITICAL AUDIOPHILE
In addition to its impressive features, the EX-M7 outperforms the award-winning integrated EX-M1 in terms of slew-rate, SNR, dynamic range, and instantaneous current supply (72VDC, 18A peak current), making it a remarkable stereo power amp.
When paired with its natural mate, the EX-P7 preamp, you'll have a premium amplification solution for even the most difficult-to-drive loudspeakers, allowing you to fully experience the subtleties and nuances of your music collection.
VERSATILE STEREO POWER AMP
The EX-M7 is also fitted with a 12V trigger, which makes it an ideal partner for a premium AVR to enhance the home theater experience. It can be used to drive the Front L/R loudspeakers, as well as all the multi-channel loudspeakers in the system, by using multiple sets of EX-M7.
This means that you can enjoy high-quality amplification for the Front L/R, Rear L/R, Front Height L/R, and other speakers in your system.
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 250 watts into 4-8 ohms, ensuring reliable and high-quality audio performance.
The EX-M7 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-M7 boasts an impressive 250 watts RMS power output into 8 ohms, making it one of the few power 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-M7 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.

We highly recommend pairing the EX-M7 stereo power amp with our award-winning EX-P7 preamp for optimal performance. Our amplifiers are Direct-DC-Coupled, which means that there are no capacitors in the signal path. This yields less coloration, higher resolution, and a more transparent and fast sound quality.
We do not recommend using a DC-Coupled OTL tube-based preamp with our amplifiers, as the DC-offset of such preamps may fluctuate as the tube ages and deteriorates. This can result in slight pops or clicks being heard through the speakers.
In general, we recommend keeping the DC-offset of your preamp/source at or below 50mVDC to minimize the risk of damage to your speakers.
It's worth noting that the DC-offset can be harmful to your speakers. However, our amplifiers are equipped with a Speaker Protection circuit at the output stage, which triggers to cut off the amplifier output (to protect the speakers) when it detects a 0.8VDC at the speaker output.
