It's a beautiful item. Sennheiser's high spec current headphone amplifier. It has a built-in D/A converter and is compatible with DSD256 files and PCM384 kHz/32 bit (when connected via 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 are no noticeable scratches and the condition is good (Sasaki Shota)
