Resonessence Labs Herus+ USB DAC/Headphone Amplifier
HERUS is an asynchronous USB Audio 2.0, 24bit 352.8Ks/S, DXD and DSD64/128, 2.4VRMS Headphone DAC. The perfect companion to anyone who enjoys music, the HERUS fits perfectly in your laptop bag or pocket, and replaces the functionality of the soundcard normally found in a laptop or desktop computer. HERUS+ is an advanced HERUS design that adds a low power mode and selectable oversampling filters. HERUS+ runs longer on your cell-phone battery and sounds even better than the HERUS when playing conventional 44.1 and 48k music because it offers customised up-sampling filters.
