hilidac has created the MQA-Supported Beam 3S which enables you to experience the abundant music details in the artists' recording room. MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. Beam 3S includes MQA Renderer technology, which can connect to an MQA Core signal and complete the final unfold of an MQA file. The Beam 3S is the  4.4mm BAL earphone ports USB PDAC. The Beam 3S LED glows magenta to indicate the unit is rendering an MQA stream or file, where the final MQA unfold is delivered. Sporting a single ES9281AC PRO chip from ESS featuring HyperStream II QUAD DAC which allows the left and right channel to operate independently. This, coupled with a dual OP-AMP configuration ensures a True Balanced design for the DAC/Amp. It also comes equipped with two ultra-low femtosecond phase crystal oscillators designed to provide best-in-class audio performance at 118 dB DNR and 0.0003% THD + N.
