FEATURES:

The Burr-Brown True Native® chipset means file formats remain unchanged or ‘bit-perfect’. This means you are listening to music as the artist intended in the format in which it was recorded. Doubling the DAC chips results in 3dB lower noise floor and better channel separation. Together with power supply advancements and advanced channel interleaving, the noise floor has been halved. All of this equals stellar sonic performance.

Hi-res audio support is state-of-the-art with True Native® playback. It handles PCM data to 32-bit/768kHz, DSD up to DSD512 and single and double speed DXD. Thanks to the Burr-Brown DAC chip’s four-channel True Native design, PCM and DSD take separate pathways – this enables DSD, as well as PCM, to remain ‘bit-perfect’ in its native form right through to analogue conversion. This is not the case with all DAC devices from other brands – even if DSD compatibility is stated, many such DACs convert DSD signals to PCM.

Listen to Master Quality Authenticated audio straight out of the box. Connect to Tidal Masters and check the option to stream MQA. MQA is an award-winning audio technology that enables music fans to stream the original master recording into their home, car or on their mobile. In the words of Gilbert O’Sullivan, iconic Irish-born singer-songwriter, “The great thing about MQA is that it delivers the finesse that was there in the desk sound. It’s tremendous, it sounds really good.”

Texas Instruments low-noise ICs offer great unity-gain bandwidth, very low noise and distortion, high output drive capability, Common-mode and Power Supply Rejection Ratios of over 100 dB, wide maximum-output-swing bandwidths and high slew rates.

Panasonic OS-CON caps totaling 5,410uF give very-low Equivalent Series Resistance (ESR), excellent noise reduction capability and frequency response characteristics. In addition, OS-CONs have a long-life span and its ESR changes little even at low temperatures since the electrolyte is solid. They are not often found in products costing
