The world’s first DAC +Amp + Headphone stand

The unique design of the EF600 serves more than aesthetic purposes: it’s also a functional headphone stand. This space-saving feature allows you to stow your favorite pair of headphones directly on the EF600, eliminating the need for a separate headphone stand. 

R2R Ladder DAC

Unlike most DACs on the market, which use “Sigma” D/A chips from companies like ESS and AKM, the EF600 uses a “ladder” method to convert the digital signal from your computer into the analog signal you hear in your headphones. This approach uses an array of highly accurate resistors for tremendous musicality.

HD Bluetooth 

With Bluetooth, wirelessly connect a phone, laptop, tablet, or streamer to the EF600 and enjoy hi-def codecs like LDAC, which deliver lossless sound reproduction for audiophile-grade sonics.

RCA + XLR inputs

Connect a turntable, CD or SACD player, and enjoy the EF600 as a high-performance headphone amplifier that’s fully compatible with most players via RCA and XLR. 

Massive 5W per channel output power  

Power will never be a problem with this DAC/Amp. Delivering 5 watts per channel @32Ω, the EF600 can drive the vast majority of low-efficiency planar headphones, including the HIFIMAN Susvara.

Balanced + S/E outputs

You’ll find four balanced outputs on the front panel: 6.35mm single-ended, 3.5mm single-ended, 4.4mm balanced, and XLR four-pin balanced.
