ANK Audio Kits DAC 2.1 Signature
Best high fidelity sound for dedicated audio DIY enthusiasts.
The DAC 2.1 Signature offers audiophile-grade sound quality with its R-2R conversion, 6922 tube line stage, and M2 Power Supply. It features AudioNote tantalums and copper film caps for a rich analog feel to your digital streams. The DAC utilizes IV transformers for seamless current-to-voltage transition and a tube-rectified, regulated power supply for ultimate smoothness. With no analog filtering, it delivers pure digital-to-analog conversion for a natural, undigital sound. This DAC hits well above its price point and can be upgraded to the DAC 4.1.

Know before you buy
Unlike common delta-sigma chips found in most modern DACs, the R-2R resistor ladder architecture processes digital signals using a precise array of resistors. This approach is favored by audiophiles for its natural, organic sound profile that avoids the harshness sometimes associated with digital processing.
Yes, as a tube-based component, you will eventually need to replace the 6922 output tubes, the ECL82, and the 6X5 rectifier tube. These are standard, readily available vacuum tubes, and the modular design of the kit makes them relatively straightforward to swap out when they reach the end of their lifespan.
No, the DAC 2.1 Signature does not feature an onboard volume control. You will need to connect it to a preamplifier or an integrated amplifier to manage the volume levels before the signal reaches your speakers.
By removing analog filtering, the signal path remains as pure as possible, which helps preserve the transient response and phase accuracy of your music. This design choice contributes to the DAC's signature 'undigital' sound, providing a more lifelike and dynamic listening experience.
Yes, the DAC 2.1 Signature is designed with an upgrade path in mind and can be converted to the DAC 4.1 specification. This allows you to scale your system's performance as your audio setup evolves.
The unit comes standard with a 75 Ohm RCA (S/PDIF) input and a 110 Ohm AES/EBU input. You can also opt for an additional USB input board if you plan to stream audio directly from a computer.
