Perfect if you listen to DSD files or just wanting a really audiophile/studio grade portable USB DAC/Amp. Can go up to 32bit/384kHz and easily handle 16-600 ohm headphones. Currently using these with Sennheiser IE80, IE800, HD8 DJ and HD800S and sound great with any genre with absolutely no distortion. Replacing my Fiio E17K with this.
