Chord Hugo DAC/Headphone Amplifier

Chord’s Hugo employs the same FPGA DAC technology with maximum tap length filters for best sound quality in its ground-breaking DAC 64. Hugo features 26k tap-length digital filters in a reference-level portable 32-bit DAC and headphone amp that offers “studio-master-tape sound quality, advanced connectivity and uncompromising file playback capability” in a small player. The five digital inputs include A2DP aptX Bluetooth and 384kHz PCM and DSD 128 playback to decode high-resolution DXD (Digital eXtreme Definition) music files. There are 2 USB inputs: legacy USB and high-definition USB port (384kHz). Two additional digital inputs, coaxial and optical, provide versatile connectivity.

The Hugo’s A2DP Bluetooth circuitry employs a custom-made module with the aptX codec for lossless digital transfer into the DAC. It processes DSD 128 data under the latest DSD-over-PCM standard (DoP). Comes with proprietary driver software in Windows and Mac format.

The FPGA DAC itself draws only 0.7V, the rest of the battery supply powers the high quality, onboard headphone amplifier with excellent output characteristics (high output drive voltage and current). A touch-sensitive digital control adjusts the volume and changes color with the volume. A 3-setting crossfeed filter helps replicate interaural crosstalk to simulate stereo loudspeaker listening and 3D imaging. The built-in battery recharges in about two hours and runs for up to 14 hours. Hugo draws no power from its USB inputs, so that the data signal remains clean and compatible with low-power devices such as tablets and smartphones.

The Hugo is housed in an aircraft-grade, anodized aluminum enclosure. A top-mounted “porthole” changes color with sample rates. In addition to the 4 digital input jacks, there are two 3.5mm headphone jacks, one 6.35mm (1/4 inch) headphone jack and 1 pair stereo RCA phono output jacks.
