Kinki Studio EX-B7 Monoblocks
Absolute Control. Unlimited Headroom. Pure Musical Emotion.
The Kinki Studio EX-B7 Monoblock Power Amplifiers are a pinnacle expression of high-current, wide-bandwidth amplifier design—engineered to deliver uncompromising power, speed, and resolution to the most demanding loudspeakers. Designed for those who seek ultimate channel separation, superior dynamics, and immense headroom, the EX-B7s are not just amplifiers—they are instruments of authority in a high-fidelity system.
Each EX-B7 is a true monaural amplifier, purpose-built with its own dedicated power supply, output stage, and signal path—ensuring zero crosstalk and maximum channel independence. This results in outstanding stereo imaging, greater dynamic swing, and the ability to effortlessly reproduce complex musical passages with absolute control and finesse.
Internally, the EX-B7 showcases Kinki Studio’s no-compromise engineering:
- A 400VA encapsulated toroidal transformer per unit feeds an ultra-fast rectifier and high-capacity reservoir for deep, unshakable current reserves.
- The discrete, fully symmetrical Class AB design delivers a staggering 250W into 8 ohms and 500W into 4 ohms—ideal for power-hungry or low-efficiency speakers.
- Meticulously selected audio-grade components populate a dual-layer, gold-plated PCB layout optimized for signal integrity and thermal efficiency.
- A short signal path and extensive local decoupling ensure low noise, fast transients, and a natural, highly resolved sound.
The result is an amplifier that offers not just brute strength, but an astonishingly refined musical presentation. Notes bloom effortlessly, imaging is deep and holographic, and transient response is lightning-fast without ever sounding etched or clinical. These monoblocks shine with music that demands both delicacy and drive—from solo piano to full orchestral works, or modern electronic productions.
Why Choose Monoblocks Like the EX-B7 Over a Stereo Power Amp?
- Dedicated power supply per channel means no sharing of current or thermal resources—leading to better stability under load and improved dynamics.
- Physical separation reduces electromagnetic interference and enhances stereo separation.
- Scalability—ideal for future bi-amping configurations or for driving extremely difficult speaker loads with headroom to spare.
- System synergy—monoblocks allow more flexible placement, ideal for short speaker cable runs, and better left/right channel balancing in acoustically sensitive rooms.
