Two conversion paths for PCM and DSD

The Audalytic DR80 is a desktop DAC based on a proprietary 26-bit discrete R-2R converter with a complementary configuration. For PCM signals, the module employs a network of precision resistors whose precise calibration supports the accuracy of the conversion. Custom-programmed FPGA logic handles clock management and digital signal processing. Three digital filters and a selectable NOS mode offer additional options for customizing playback.

DSD recordings follow a separate path. When DSD Direct mode is activated, the bitstream goes directly to a 1-bit switch array decoder, completely bypassing PCM conversion. Native DSD up to DSD1024 is supported via USB, and up to DSD2048 via a compatible I2S source.

USB Interface Developed in Collaboration with Amanero

Both models in the series use a USB audio interface developed by Gustard in collaboration with the Italian manufacturer Amanero. Its ARM Cortex-M7 processor handles the demands of high data rates and processes PCM up to 32-bit/768 kHz, native DSD up to DSD1024, and DoP up to DSD512.

Digital Inputs

USB-B, coaxial, optical, I2S, and Bluetooth are available for computers, portable players, and wireless sources. The coaxial and optical inputs support PCM up to 24-bit/192 kHz as well as DSD64 via DoP. The I2S input extends PCM support to 32-bit/1536 kHz and offers four selectable pin configurations to adapt it to compatible sources. The HDMI-style jack transmits I2S audio exclusively. HDMI audio/video and ARC/eARC are not supported.

Wireless playback is handled by a Qualcomm QCC5125 chipset with Bluetooth 5.1. Supported codecs include LDAC (24-bit, 44.1 to 96 kHz), AAC, SBC, aptX, aptX LL, and aptX HD.

Analog Volume Control and Simultaneous Outputs

An analog volume control IC allows for level adjustment when connecting to downstream amplifiers. A true bypass mode is available for systems that already have their own volume control. At a fixed volume, the balanced XLR outputs deliver 4 V rms and the unbalanced RCA outputs deliver 2 V rms.

Both output types can be operated simultaneously, allowing two downstream devices to be connected. The output impedance is 100 Ω for each.

The published measurement values indicate a dynamic range of over 114 dB, a signal-to-noise ratio of over 115 dB, and a THD+N of no more than 0.003% at 1 kHz.

Clock, Power Supply, and Operation

A CK-01 femto-clock module provides the DAC’s time base. Segmented filtering and multiple regulated power rails minimize interference between circuit sections. Both models feature an internal low-noise power supply as well as an external DC input for 12 to 15 V, which requires a power supply capable of delivering at least 2 A.

Controls and settings are accessed via touch controls on the front panel or via an IR remote control. The LCD features adjustable brightness and a sleep mode. The housing is made of anodized aluminum and is available in black or silver.

DR80 or DR80n

The DR80 connects to your existing digital sources. For those who also want network playback, the DR80n is the model featuring an integrated CelWare network bridge, a LAN port, and a microSD slot.
