Pros
Exceptionally dynamic, fast and energetic presentation with convincing live-event impact.
Deep, powerful bass combines strong damping, grip, punch and definition.
Clear, smooth and layered midrange with spacious soundstage and precise imaging.
Strong value for high-power monoblocks, with performance reviewers compared favorably to substantially pricier alternatives.
Cons
Its ultra-resolving, high-energy character can expose preamp or system mismatches, including treble thinness or noise in an unsuitable chain.
The close-to-stage intensity may be less suitable for listeners seeking a relaxed, laid-back presentation or very long sessions.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 94/100
Reviewers consistently describe an unusually clear, fast and forceful presentation, combining muscular bass control with a full-bodied, engaging tonal character. The EX-B7 is portrayed as especially compelling for listeners who want close-to-the-action energy without the grain, glare or fatigue often associated with high-powered solid-state amplification.
Transparency Resolution
95/100
The EX-B7 receives repeated praise for clarity, resolution and freedom from haze. Reviewers describe an extremely resolved top end, enhanced vocal detail and layering, and a presentation that removes the sense of a curtain or fog from the music; one comparison specifically credits it with banishing grain and subliminal sizzle.
Tonal Balance Musicality
92/100
Its character is broadly described as neutral, clean and musically engaging, with a slight warmth and welcome bottom-end muscularity. Reviewers also hear fuller, weightier and more tonally saturated sound than some rivals, with a smooth, non-edgy midrange and less listening fatigue than certain solid-state alternatives.
Dynamics
96/100
Dynamics are a defining strength. Reviews call the EX-B7 seriously dynamic, demonstrably fast and electrifying, with substantial impact, rise and musical charge; its powerful low end is repeatedly praised for grip, damping, punch and control. Reviewers also report that it drives demanding loudspeakers confidently, including loads that dip very low in impedance.
Soundstage Imaging
92/100
The EX-B7 is credited with spaciousness, air, strong separation and highly precise image placement. One reviewer found it produced the largest stage and more accurate imaging than the compared Naim and Hegel amplifiers, while another characterized its presentation as vivid and physically present rather than distant or overly venue-focused.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
91/100
The compact monoblocks use a wide-bandwidth, DC-coupled circuit, a 750VA transformer, separated control and protection circuitry, upgraded fault protection and a copper transistor-mounting wedge integrated into the front panel. Balanced and RCA inputs are accommodated without manual switching, and the quoted power, high current capability and substantial damping support their intended role as serious speaker-driving amplifiers.
Value for Money
96/100
At approximately $3,498 per pair or around €4,000, reviewers consider the EX-B7 exceptional value among high-power monoblocks. One reviewer found that only far more expensive amplifiers bettered it in his system, while others call its performance at the asking price "absolutely insane" and regard it as a standout choice in its class.

Manufacturer's Description — Kinki Studio
The pinnacle of the EX Series — a statement monoblock with a massive power-reservoir capacitor farm, four pairs of lateral Exicon MOSFETs and a 750 VA toroidal transformer in each chassis. Double the EX-M1’s output, with the same tonal quality and resolution. Price is for a pair.
Designed for the critical audiophile
The EX-B7 outperforms the EX-M1 in power delivery, headroom and dynamic range — an exceptional choice for demanding loudspeakers, especially paired with the EX-P7 preamp.
Built on an extremely high-cost 0.2µm gold-plated PCB with increased solder area and added shielding for optimal performance.
Optimised power supply
High-efficiency toroidal transformers and large filtering capacitor reservoirs provide a constant, stable current supply.
The substantial components deliver energy with minimal distortion even during demanding dynamic peaks — clean, accurate sound at all times.
High-damping modular power stage
Power circuitry on a custom gold-anodised heat sink, with Exicon MOSFETs driven in Class A/B, delivering 250 watts into 4–8Ω per monoblock.
Crafted to perfection
The EX-B7 is capable of far higher wattage than its stated figures — but we take a conservative approach rather than play a numbers game.
Careful design, component selection and tuning deliver neutrality and musicality: rich tonal quality, vivid imaging, exceptional detail and dynamic range.
