*Red indicates that the units is rendering a file at 44.1/48kHz; 

*Blue indicates that the units is rendering a file at 88.2kHz - 384kHz;

*Green indicates that the units is rendering a file at 705kHz - 768kHz;

*Yellow indicates DoP;

*White indicates that the unit is rendering a DSD native file.

Featuring the ES9281AC PRO chip from ESS, REA-680 is equipped with a crystal oscillator designed to provide best-in-class audio performance at 118 dB SNR and 0.0004% THD + N.

* Coupled with the specially-engineered AWR circuit (USB impurity filter), REA-680 delivers a high-quality sound similar to that from HI-END audio system set up, 

an expansive sound stage and texture and details with distinct width, abysmal  depth and soaring height.
