Pros
Exceptional transient speed, dynamic slam and firm driver control give bass real impact without sacrificing agility.
Open, deeply dimensional soundstage with precise image placement and strong layering.
Natural, full-bodied mids and textured, clean treble avoid dryness and aggressive brightness.
Robust 25kg construction plus useful DC filtering, ground management, RCA/XLR inputs and trigger connectivity.
Cons
Runs hot and needs a properly ventilated rack with enough space for its large, heavy chassis.
Its speed and control can sound slightly overemphasized in systems already voiced for an especially incisive top end.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 94/100
Reviewers portray the EX-M7 as a powerful but refined Class A/B amplifier, combining dense, natural tone with exceptional grip, transient impact and expansive imaging. Its presentation is repeatedly described as open, clean and controlled, though one listener found its speed could be slightly overplayed with a super-tweeter setup.
Transparency Resolution
93/100
Soundnews heard abundant top-octave information, clean texture and a grain-free treble that avoided brightness or dryness. Alpha Audio likewise attributed its unusually wide bandwidth to an audibly unrestricted spectrum, while 6 Moons noted superior clarity extending into the low registers.
Tonal Balance Musicality
92/100
The tonal character is consistently described as natural, full-bodied and organic rather than sterile. Soundnews praised substantial, vivid midrange and natural treble texture, while 6 Moons heard a generous, lush pairing; with a super tweeter, however, it felt the amplifier slightly overemphasized its own speed.
Dynamics
96/100
This is the EX-M7's most emphatically praised area. Reviewers describe exceptional bass slam, taut driver control, lightning-fast transients and substantial voltage-swing headroom; Soundnews called it among the best dynamics and body slam heard in its system, while 6 Moons repeatedly highlighted its control and macro-scale power.
Soundstage Imaging
95/100
The amplifier earned unusually strong praise for spatial precision and scale. Soundnews reported a broad, deeply dimensional presentation with pinpoint placement, while 6 Moons described laser-locked images even at the stage extremes and a holographic wall-to-wall effect.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
94/100
The EX-M7 is reported to be exceptionally substantial in execution, with thick aluminum panels, heavy-duty feet and a 25kg chassis that Soundnews characterized as tank-like. Practical engineering is also well considered, including balanced and single-ended inputs, trigger connections, a Furutech AC inlet, selectable DC filtering and chassis-ground management; 6 Moons also praised the brand's workmanship and assembly standards.
Value for Money
91/100
At roughly $2,798, reviewers acknowledge that the EX-M7 is not inexpensive, but regard its pricing as justified by its combination of power, refinement and construction. Soundnews called it expensive but understandable and wholeheartedly recommended it, while 6 Moons considered its high-power performance and execution unusually compelling for under €3,000.

Manufacturer's Description — Kinki Studio
Dual encapsulated 400 VA toroidal transformers, two pairs of lateral Exicon MOSFETs and a large reservoir capacitor bank — an upgraded EX-M1 in stereo power-amp form.
Designed for the critical audiophile
The EX-M7 outperforms the EX-M1 in slew-rate, SNR, dynamic range and instantaneous current (72VDC, 18A peak).
Paired with the EX-P7 preamp, it forms a premium solution for even the most difficult loudspeakers.
A versatile power amplifier
A 12V trigger makes the EX-M7 an ideal partner for a premium AVR — drive the Front L/R, and add more EX-M7s for Rear, Height and other channels.
High-damping modular power stage
Power circuitry on a gold-anodised heat sink, two pairs of Exicon MOSFETs per module in Class A/B.
High damping factor, ultra-high slew rate and a DC-coupled path deliver neutral, transparent sound and exceptional transient speed.
Preamp matching
We recommend pairing the EX-M7 with the award-winning EX-P7. Our amplifiers are Direct-DC-Coupled — no capacitors in the path — for less coloration and higher resolution.
A speaker-protection circuit triggers if it detects 0.8VDC, safeguarding your loudspeakers.
