Sennheiser's high-spec current headphone amplifier. It has a built-in D/A converter and is compatible with DSD256 files and up to PCM384 kHz/32 bit (when connected to USB). You can enjoy the sharp and clear sound. The combination with the company's HD800S is the best match, so if you have one, don't miss it. There is a line scratch on the top plate on the exterior (Mizusaki Ryo)
