Experience high-quality audio with the HIFIMAN EF400 R2R Balanced Desktop DAC-Headphone Amp, featuring Hifiman’s proprietary Himalaya R2R technology and a cornucopia of options. These options include High Gain NOS (non-oversampling), High Gain OS (oversampling), Low Gain NOS & Low Gain OS listening modes and your choice of 6.3mm, 3.5mm, 4.4mm & XLR-4 headphone jacks on the front of the device & USB-B and USB-C connections, along with RCA and balanced XLR outputs on the back. You can also easily switch the voltage to meet either US or international standards on bottom of the EF400. This is a pre-owned item and I’m the original owner. I tested it just before entering this listing and all the headphone jacks and listening modes work without any issues. It will be shipped via priority mail, in the original packaging from Hifiman, including the original protective foam inserts and including the unused original power cord (as I always used an aftermarket power cord). I’ve also included a generic USB-C to USB-C and USB-B to USB-A cable, just in case the buyer needs either to get started. This DAC-headphone amp does have some small paint scratches, which are shown in the attached photographs, including close-up photos focusing specifically on them. However, these scratches are only surface-level and not dents or anything that impacts audio quality or functionality. I rarely notice them from the distance and angle in my own set-up, but your perspective may vary and I know people can have different feelings about such things, so please make sure to look through the photos before purchasing or making an offer. I’m listing this EF400 at a lower price than others on eBay because of this purely cosmetic issue, so this is an opportunity to buy a well-reviewed newer (2022) R2R DAC and headphone amp from Hifiman that works perfectly, along with the original packaging and power cord, at a discount. Thank you for checking out my listing!
