About the dAck! 2.0

The Ack! Industries dAck! 2.0 is a high-performance digital-to-analog converter (DAC) that uses a unique filterless design and a battery-based power supply to deliver extraordinary pace, timing, and tonal purity in music reproduction. It features a non-oversampling conversion stage based on the Philips TDA1545A continuous calibration DAC chip, providing exceptional transparency, soundstage expansion, and timbral accuracy without fatiguing dynamics. The unit is compact, with CNC-machined aluminum front and rear plates mounted on a steel enclosure, and the circuit is suspension-mounted to reduce vibrations. The battery power supply isolates the DAC from noise and interference common in digital sources, enhancing sound quality. The dAck! 2.0 includes a high-bandwidth BNC digital input (>2GHz bandwidth) with a BNC-to-RCA adapter and comes with a proprietary high-bandwidth 75Ω BNC digital cable. Output jacks are upgraded to high-quality Teflon RCA connectors. The DAC requires careful battery charging and usage habits to maintain optimal performance, with straightforward battery replacement. It is compatible with AES and S/PDIF digital signals and designed to interface well with noisy digital sources such as PCs. The dAck! 2.0 is highly regarded for its musicality, speed of attack and decay, taut bass detail, and extended liquid highs, making it a valued component in audiophile systems.
