Mass-Kobo<\/a>‘s\u00a0choice of current-mode signal has been around as long as Head-Fi has,\u00a0<\/span>and the portable, battery-powered, Model\u00a0475 calls upon such heritage.\u00a0<\/p>\n

<\/p>\n

Model\u00a0475 presents music with an\u00a0iron\u00a0<\/span>grip on your transducers, never allowing the slightest note out of control.<\/p>\n

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.<\/span><\/p>\n

Mass-Kobo presents your favourite music with a zeal and vibrancy that’s accurate and still entertaining.<\/p>\n

Another effect of being unhindered by capacitance in the signal path means that huge signal bandwidth is possible, with phase\u00a0response excellently preserved in the human hearing range for startlingly life-like dynamics, impactful bass and realistic portrayal of musical images.\u00a0<\/p>\n

Indeed, to hear current-mode is to hear a precision\u00a0to music not encountered before in a conventional circuit, and\u00a0Mass-Kobo\u00a0<\/span>build\u00a0Model 475\u00a0<\/span>as testament to such a topology.<\/p>\n

Current-mode technology excels the\u00a0more it detects a dead short, so\u00a0Model\u00a0475 only works more happily when presented with sub-30ohm loads from Audeze’s LCD-5, Dan Clark Audio’s Stealth, Expanse and E3,\u00a0plus\u00a0HIFIMAN<\/a>‘s latest flagship generation.<\/p>\n

Feed Mass-Kobo only the finest signal. Keep your whole chain working in\u00a0current-mode with\u00a0Questyle Audio<\/a>‘s\u00a0CMA18P<\/a>\u00a0and M15i<\/a>. From a player, Cayin Audio<\/a>‘s N7<\/a> has the consummate sound quality, and more importantly line output stage, necessary to drive Model 465’s low-impedance current-mode input stage<\/p>\n
