Mass Kobo Model 475 Portable Headphone Amplifier

$2,399 $2,399

Mass-Kobo's choice of current-mode signal has been around as long as Head-Fi has, and the portable, battery-powered, Model 475 calls upon such heritage. 

Current-mode amplification eliminates the lag time that might otherwise occur when signal is transmitted in voltage, as it builds up at the capacitances in the circuit – current signal passes through unhindered by comparison, with speed and ease.

By doing away with the issue of transmission delay in Model 475, Mass-Kobo virtually eliminates any of the harshness caused by the intermodulation distortion associated with high capacitance, solid-state circuits. [See Product Desc. For More]

Product Description

Model 475 presents music with an iron grip on your transducers, never allowing the slightest note out of control.

Any trace of transient smear or note bleed vanishes, from the lowest bass to the highest highs, given the extraordinary damping factor current-mode delivers.

Mass-Kobo presents your favourite music with a zeal and vibrancy that's accurate and still entertaining.

Another effect of being unhindered by capacitance in the signal path means that huge signal bandwidth is possible, with phase response excellently preserved in the human hearing range for startlingly life-like dynamics, impactful bass and realistic portrayal of musical images. 

Indeed, to hear current-mode is to hear a precision to music not encountered before in a conventional circuit, and Mass-Kobo build Model 475 as testament to such a topology.

Current-mode technology excels the more it detects a dead short, so Model 475 only works more happily when presented with sub-30ohm loads from Audeze's LCD-5, Dan Clark Audio's Stealth, Expanse and E3, plus HIFIMAN's latest flagship generation.

Feed Mass-Kobo only the finest signal. Keep your whole chain working in current-mode with Questyle Audio's CMA18P and M15i. From a player, Cayin Audio's N7 has the consummate sound quality, and more importantly line output stage, necessary to drive Model 465's low-impedance current-mode input stage
