{"product_id":"hifiman-ef600-amplifier-and-dac-open-box","title":"Hifiman EF600 Amplifier and DAC (Open Box)","description":"\u003cp\u003eDesigned for use as a DAC, or independent headphone amplifier, the EF600 features an industrial design that is not only aesthetically appealing, it also serves as a headphone stand, reducing desktop clutter. Included are fully balanced input\/output connections, high-resolution Bluetooth connectivity, an independent power supply and a thermal optimized tower case.\u003c\/p\u003e\n\u003cp\u003eThe EF600 includes two Hymalaya Pro modules for unsurpassed sonic output, especially when compared to the more commonplace PCM1704k module. The Hymalaya Pro, with the added support of a new algorithm and 0.01% precision resistors, reaches a THD (total harmonic distortion) rate of -60dB 2%. In plain English, distortion is reduced to a previously unheard of low with no audible distractions.\u003c\/p\u003e\n\u003cp\u003eBluetooth connectivity is achieved with an upgraded design that supports multiple codecs, including LDAC, delivering lossless sound reproduction for audiophile-level sonics.\u003c\/p\u003e\n\u003cp\u003eAn array of RCA and XLR inputs allows the EF600 to be used as a high-performance headphone amplifier that is fully compatible with most CD and SACD players, thanks to its balanced output.\u003c\/p\u003e\n\u003cp\u003eThe EF600 requires the bare minimum of desktop or rack space. The physical dimensions are: 104mm\/4” x 135mm\/5 1\/4” (top); 104mm\/4” x 165mm\/6 1\/2” (bottom) ; 283mm\/11”(height). A new industrial design that serves as a headphone stand when the DAC\/amp is not in use.\u003c\/p\u003e\n\u003cp\u003eThe front panel includes four balanced outputs – 6.35mm single-ended, 3.5mm single-ended, 4.4mm balanced, XLR four-pin balanced – in addition to a four-level function switch and volume control. The rear input panel includes jacks for RCA, USB-B, and USB-C source connectors, in addition to dual (L\/R) XLR three-pin full balanced line outputs.\u003c\/p\u003e\n\u003cp\u003eSignal-to-noise ratio is measured at 118dB (weighted), channel separation is 131+\/-3dB, and THD+N (line out) is 0.0014% (-8dB).\u003c\/p\u003e\n\u003cp\u003eMaximum power output is robust at 5.12 wpc @32R balanced\/1.8 wpc @32R unbalanced, giving the EF600 the power to drive the majority of low-efficiency planar headphones, including HIFIMAN Electronics’ flagship model, Susvara.\u003c\/p\u003e","brand":"HIFIMAN","offers":[{"title":"Default Title","offer_id":47723660837097,"sku":"EF600 (OB)","price":551.65,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/products\/HIFIMAN-EF600-2.jpg?v=1762463934","url":"https:\/\/audio46.mom\/products\/hifiman-ef600-amplifier-and-dac-open-box","provider":"Audio46 Headphone Store","version":"1.0","type":"link"}
