Kinki Studio EX-B7 - statement monoblocks power amp (silver)
The EX Series is tuned to reproduce sound quality with balance mid and smooth extension in both ends, high and low extension. The EX-B7 is the statement monoblocks power amp. Each monoblock is equipped with dual 300VA UK Made Amplimo Toroidal Transformers, 4 pairs of EXICON Laterals MOSFET and a huge power reservoir capacitors farm. It is essential doubled of what the award-winning EX-M1 offered. The good of EX-M1 remains, rich in tonal quality, details, dynamic, and high resolutions.
250Watts RMS into 8Ω
Right, we are being conservative. The monos can technically deliver a lot higher watts than what is stated. We do not want to get into the number games. We trust you as the smart consumer, you are not looking at just the number. The design, choice of components, tuning, is the key of good sounds.
- 4 pairs of Mosfet transistors from the British Exicon (fast and dynamic)
- 750VA transformer from the British AMPLIMO
- American Vishay BC capacitors / Epcos
- Extremely high cost 0.2µm gold-plated printed circuit board (PCB)
- Gold-plated connectors for input stage signal and transformer primary stage.
Power supply circuitry is designed for optimum stability.
The massive power supply with high-efficiency toroidal transformers and large filtering capacitors reservoir ensures a stable current supply at all times.
Neutrality and musicality were the goals to achieve. Rich tonal quality, vivid sound imaging, details, high resolution and dynamic. The choice of the components, design, and tuning does just that.
