Audio Alchemy DDP-1 Features:

  • 3-in-1 Analog preamp, DAC with dual digital signal processors and headphone amp
  • Resolution enhancement from 16 to 24-bit and 24 to 32-bit digital signals
  • Seven digital inputs supporting a myriad of music players, PCs and media devices
  • Three analog inputs to ensure your entire music collection stays on heavy rotation
  • Small, highly attractive design equally at home in tabletop or desktop use in smaller rooms or offices or high-end system rack
  • A USB connector allows easy firmware updates
  • Control is easy, thanks to an IR remote and illuminated front LCD
  • Upgradeable through addition of PS-5 external power supply to boost overall performance

In an attempt to make our digital world a better sounding place, we set out to create the highest quality Preamp/ DAC/ Headphone Amp that could deliver exceptional, world-class sound for under $10,000. The result is the DDP-1, a three-in-one powerful all-analog preamplifier, DSD-compatible digital-to-analog converter with dual digital signal processors and a headphone amp, all housed in one compact machined-aluminum chassis for under $2,000.

Refine and redefine digital

Unlike most digital preamps and DACs, the DDP-1 employs sophisticated digital processing that gives it superior sound quality, dramatic noise reduction and flexibility. The ability to select from four output filter profiles and output resolutions means that you can get the most out of each digital file. Layered on top is Audio Alchemy’s world-renowned jitter control technology, which gives digital files that smooth, velvety analog quality we all love. Add the modular PS-5, a balanced power supply to maximize the DDP-1’s dynamic range and filtering to produce a rich sound that can compete with much larger and more expensive units.

Sound engineering

The digital section uses dual 32/216 PCM/DSD AKM DACs with seven digital inputs. Internal DSPs provide four output filter profiles and user-selectable output resolution. A proprietary DAC configuration raises dynamic range of digital signals by approximately 8 bits, and a multistage phase-locked loop reduces jitter to the picosecond level. The analog section provides discrete FET driver and output stages, a high-precision Alps volume control and XLR and RCA inputs and outputs.
