Ideon Audio eos DXD/DSD DAC
Breakthrough technology from the Absolute and IΩN series: an affordable reference DAC
The Ideon Audio eos DAC incorporates advanced technologies and research derived primarily from our extensive work on the IΩN DAC and our flagship Absolute Epsilon, which has set global benchmarks.
HyperStream, 8-channels architecture with proprietary, cutting-edge analog stage
- High output impedance at -120 dB SNR, quad current output from DAC
- Cutting edge analog stage, with symmetrical ultra-low noise power supply – in a unique topology
- Low-noise power through, more than 10 different separate power regulators in the circuit.
- Direct coupled output with no capacitors in the output stage.
- In-House fully balanced design throughout.
The Symmetrical Analog Output Principle
The balanced output, designed internally, features symmetrical analog output channels without capacitors in the signal path and utilizes dedicated power supplies within a distinctive topology. This design approach is also implemented in the eos DAC.
Design for future upgrades
Low noise power supply
Proprietary Triple Distillation USB input: Noise Elimination
Featured in many of our DACs and developed internally, the Ideon Audio Triple Distillation USB input incorporates a proprietary three-stage noise reduction circuit that effectively removes digital noise from the input signal. The expertise gained during the creation of the Absolute Epsilon DAC has been applied to the eos DAC as well. In essence, we have taken a rigorous approach to eliminate both linear and non-linear distortion and noise.
Clock Oscillators: Getting the Music in Phase
The eos DAC utilizes several of the oscillators found in our IΩN DAC, employing three premium femto ultra-low jitter and ultra-low phase noise clocks within a meticulously designed architecture. This guarantees precise timing and exceptional phase accuracy of the audio signal.
Each clock has its own dedicated power line.
KEY FEATURES
- Cutting edge analog stage, with symmetrical ultra-low noise power supply.
- -120 dB SNR, quad current output from DAC.
- Silicon carbide diodes deployed to minimize diode-rectification noise
- Upgradable DAC and USB input engine.
- New in-house developed dedicated software for the DAC chip (same as the Absolute E DAC). The upgradable chip firmware is developed by Ideon Audio in close cooperation with ESS.
- Native support and playback for all DSD and PCM formats/frequency rates
- Proprietary Triple Distillation USB input: Noise Elimination.
- New audio USB codec used in our USB input module. A proprietary design, being the most current, state-of-the-art technology. The result; amazing, practically zero jitter, extremely low noise, super-fast processing, and extraordinary, natural sound quality.
- A customized USB Audio 2.0 audio class driver developed for Windows. It’s optimized for low latency and low CPU load. Buffer depths can be adjusted to optimize settings for any given computer. The driver implements a transparent (bit-perfect) playback.
