“Though the Kinki unmistakably belonged to our generic Swiss school, it included that other Swiss, subtle yet distinctive, Nagra aroma. It derives from their signature obsession with tubes even though in much of their recent gear, they don’t use valves to get there. Without impact on the noise floor to maintain superb magnification powers, it injects a whiff of textural extra and transient ease. I needn’t spell out what that says about the M1’s sell price.”

EX Series M-1

The EX Series is tuned to reproduce sound quality with balance mid and smooth extension in both ends, high and low extension. The EX-M1 is fully modular, a dual mono design in a single chassis. Rich in tonal quality, details, dynamic, and high resolution. Silky smooth volume control thanks to the discrete R2R volume control, of which known for its precise and accurate volume adjustment with precision matched resistors.

R2R VOL CONTROL

Most amplifiers use a potentiometer for volume control. EX-M1 uses an advanced microprocessor-controlled, relay-based R2R steps attenuator. Ultra-precise 256 steps linear volume control allow you to fine adjust the volume for late-night-listening.

COST-NO-OBJECT

The EX-M1 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. It uses two 300VA UK made AMPLIMO transformers, one each for Left and Right channel power supplies, so that the power does not interfere with each other to improve the channel separation.
