Soekris DAC 1421
Best high fidelity sound for value conscious audiophiles.
The Soekris DAC 1421 is a high-performance single-ended DAC featuring a built-in, powerful headphone amplifier. It utilizes the renowned Soekris R-2R technology, offering a clean and natural sound with its 27-bit R-2R sign-magnitude DAC. The device includes a fully-balanced, zero-feedback line output buffer and a high-power mode for driving headphones. Music is delivered via USB, SPDIF, AES, or Toslink inputs, with buffering and re-clocking for ultra-low jitter. Digital processing is handled by an FPGA with selectable filters and digital volume control.

Know before you buy
Unlike common delta-sigma chips that use oversampling and noise shaping, the Soekris R-2R design uses a discrete resistor ladder to convert digital signals to analog. This approach is widely favored by audiophiles for providing a more natural, organic, and less 'digital' sound signature.
Yes, the device features a high-power mode specifically designed to drive a wide range of headphones. Its integrated amplifier is robust enough to handle demanding loads while maintaining the clarity of the R-2R conversion.
The FPGA-based filters allow you to fine-tune the DAC's impulse response and frequency roll-off. You can experiment with these settings to find the balance between a sharper, more analytical sound and a smoother, more relaxed presentation.
Not necessarily. The unit includes high-quality digital volume control, allowing you to connect it directly to a power amplifier or active speakers. However, if you prefer a dedicated analog preamp, you can set the volume to maximum and use the DAC as a fixed-output source.
The DAC 1421 is highly versatile, offering USB, SPDIF, AES, and Toslink inputs. This allows you to connect everything from a computer or streamer to a dedicated CD transport or game console.
The DAC 1421 utilizes an ultra-low jitter oscillator and internal buffering to re-clock incoming digital signals. This process ensures that the timing of the data is precise, which is essential for maintaining a stable and accurate soundstage.
