Kinki Studio


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 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. 


What's more? Compare to the award-winning Integrated EX-M1, the EX-B7' power delivery, headroom, dynamic range, are simply incredible. Pairing with its natural mate EX-P7 preamp, you are all set of a premium amplification for your difficult-to-drive loudspeakers.


The EX-B7 uses extremely high cost 0.2µm gold-plated printed circuit board (PCB). From the perspective of PCBs, it is clear that the designer is well aware of the limitations on the fine contact area of the general circuit board, specifically increasing the soldered area at each solder joint and adding as much shielding as possible.

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.

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.


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. 


It is the Kinki Studio gears' sound signature.

Preamp Matching

Please consider the award winning EX-P7 to match with the monoblocks EX-B7. Kinki Studio amplifiers are Direct-DC-Coupled without any capacitors in the signal path. This yield less colouration, high resolution, fast, and transparent sound quality. 


Should you wish to use other preamp make, please be informed that we do not recommend the use of tube-based preamp. 


You may experience slight pops/clicks noise to the loudspeakers, it's likely caused by the DC-offset in the preamp.
