EF-3.01 is the first headphone amplifier of Citypulse Electron co., ltd. Designer of EF-3.01 match Hi-fi concept to PC field, which be more and more popular in the world, EF-3.01 is a headphone amplifier with individuation and fashion. 21 century is a new generation, people like individuation and personal space, EF-3.01 design circuit and appearance independently by our engineers, it use the double-face gilded plugboard, and double mini shielded ring model transformer, in the center of transformer, we use epoxy resin adhesive to fixed for reducing shake of transformer and cooling, down-lead of the transformer are enamelled wire and cover TEFLON to reduce wasting; the power supply of EF-3.01 is elaborately designed by designer, it use two module which cover with aluminum alloy and fixed on the plugboard by epoxy resin adhesive, as super power supply of EF-3.01, they steadily press power to the amplifier. The mini sizes make it easy to placed it in the personal space or computer room. On the base of them, designer put the orthodox Hi-Fi into EF-3.01, Aluminium alloy board elaborate design by CNC, shows the good quality and the tidy design, the fanciers can fully enjoy the funny of DIY, is a really individuated PC Hi-Fi center machine.
Specialty
