DAART DA2: High-End Desktop DAC with Streaming and Class A Power

The DAART DA2 arrives as a seriously ambitious desktop component, combining DAC, network streamer, preamplifier, and a fully discrete Class A headphone amplifier into a single, compact unit. Rather than focusing on one specific role, it is designed to act as the central hub of a complete audio system, equally at home driving high-end headphones or serving as the core of a desktop speaker setup.

At the heart of the DA2 is a digital platform built around FPGA architecture, paired with JIC’s proprietary signal processing. This allows for precise control over how audio data is handled before conversion, giving the unit a level of flexibility and refinement typically reserved for more complex, multi-box systems. The entire system runs on a Linux-based platform, integrating network streaming, USB input, and R2R relay volume control into a unified environment.

The DAART DA2 is a new desktop DAC and headphone amplifier with network streaming, preamplification, and a full-fledged Class A amplifier.

Clocking is handled by dual Accusilicon AS338 oscillators, ensuring accurate timing and low jitter, which is critical for preserving detail and spatial accuracy. On the conversion side, DAART combines the flagship AK4499EX DAC chip with the AK4191 modulator, delivering high-resolution PCM and DSD playback with a focus on both technical precision and musicality. The analog stage follows a fully balanced, discrete design, avoiding shortcuts and maintaining signal integrity throughout.

One of the standout features is the 100-step R2R relay volume control. Unlike traditional potentiometers, this system offers precise, repeatable adjustments without introducing additional noise or degradation. It also allows the DA2 to function as a high-quality preamplifier, capable of feeding both active speakers and external power amplifiers with confidence.

Designed as a universal hub for a home audio system, it integrates a digital transport, DAC, analog stage, and amplification unit, making it suitable for use with headphones, as well as in a desktop system with active speakers or an external amplifier.

The headphone amplifier section is equally serious. Built as a fully balanced Class A design using discrete transistors, it is engineered to handle everything from sensitive in-ear monitors to demanding full-size headphones. Multiple gain and load modes ensure proper matching, while the available power output is more than enough for even high-impedance designs. The result is an amplifier that prioritizes control, dynamics, and tonal richness.

Connectivity is extensive, reflecting the DA2’s role as a central system component. Digital inputs include network streaming, USB, AES/EBU, coaxial, and optical, while analog integration is handled via a balanced XLR input. Outputs include both balanced and single-ended line connections, along with multiple headphone outputs on the front panel, including XLR, 4.4 mm, and 6.35 mm.

The built-in display provides useful visual feedback, including VU meters, signal information, and system status, adding both functionality and a touch of classic hi-fi appeal. The chassis itself is constructed from aluminum and doubles as a heat sink, which is especially important given the Class A amplification. Internally, the unit uses a linear power supply with a toroidal transformer to ensure stable and clean power delivery, with an optional external high-power supply available for further performance gains.

The DAART DA2 features a 100-step R2R relay volume control, allowing it to be used as a preamplifier without a traditional potentiometer. The headphone amplifier is a fully balanced Class A design with discrete transistors and is designed to drive both sensitive models and full-size, high-impedance headphones. High and low impedance load modes are provided, as well as a separate output level adjustment.

In terms of raw performance, the DA2 delivers impressive numbers across the board, including high output power for both balanced and single-ended headphone connections, low distortion figures, and a wide dynamic range. Support for ultra-high-resolution PCM and DSD formats ensures compatibility with even the most demanding digital libraries, while network features such as AirPlay 2, DLNA, Roon Bridge, and HQPlayer NAA make it easy to integrate into modern streaming ecosystems.

The DAART DA2 is not just another DAC or amplifier, it is a complete system solution designed for listeners who want high-end performance without the complexity of multiple components.
