The Ideon Audio eos DAC: a High Performance DXD/DSD DAC. A class of its own

Breakthrough technology from the Absolute and IΩN series: an affordable reference DAC

The Ideon Audio eos DAC, utilizes trickle-down technologies and R&D gained, from our extensive work mostly with our IΩN DAC and our flagship Absolute Epsilon which has set new standards worldwide. 

Many of the IΩN DAC’s innovations and designs are found in the IΩN in its own scale. As with all Ideon offerings, the eos DAC is a fully proprietary design, with audio technologies developed in-house.

A bespoke handcrafted product housing an innovative combination of high-performance design features and best-of-breed quality components.

8-channel hybrid conversion engine. Fully differential parallel architecture with advanced time-domain control and a 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.

USBCore™ - Ideon Proprietary USB Input

Ideon USBCore™ represents Ideon Audio’s in-house developed USB input stage, the internal gateway through which all digital audio signals first enter the DAC:

  • Proprietary, software-driven signal optimization engine.
  • “Exotic” level femto-grade re-clocking with extremely low phase noise (< -160 dBc/Hz)
  • Multi-stage ultra-low noise (<5μV) linear power supply. 

USBCore™ secures data integrity at its very foundation. As the first stage inside the DAC, it prepares a pristine quality signal to enter the DAC conversion engine.  Partnered with external ChronoCore™ re-clocking, layer, establishes a complete end-to-end architecture for reference-grade digital playback.

Our experience from the making of the Absolute Espislon DAC has been now transfered to the IΩN as well. Figuratively speaking, we have declared war on linear & non-linear distortion and noise!

Clock Oscillators: Getting the Music in Phase

The eos DAC shares some of the same oscillators used in our IΩN Dac. It deploys three top-of-the-line femto ultra-low jitter and ultra-low phase noise clocks in a no-compromise architecture; precision and resulting phase fidelity of the signal is ensured.

Each clock has its own dedicated power line. 

The Symmetrical Analog Output Principle

The in-house designed, balanced output has symmetrical analogue output channels, with no capacitors in the signal path and dedicated power supplies, in a unique topology. This can also be found in eos DAC.

 

Design for future upgrades

The eos DAC has been designed with future upgrades in mind, like most of Ideon’s products. 

Its modular construction allows for future upgrades of different parts of the device, if and when a new technology becomes available, or a new format takes over.

Low noise power supply

eos’ multistage power reservoir comprises many different low-noise power supply units and individual regulation stages.

The importance of stable, abundant, and clean power is touted all over audio circles, but at Ideon Audio, we take things to another level: we as many separate stages as needed in order to achieve unparalleled clarity and linearity.

We choose top-level components: high-quality and performance regulators with very low-tolerance rating, and  ultra-low esr audio-grade capacitors specifically designed for audio applications.

 

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.
  • In-house developed dedicated software for controling the conversion engine (same as the Absolute E DAC). 
  • Native support and playback for all DSD and PCM formats/frequency rates
  • Ideon Audio’s Proprietary USBCore™, USB input  (also found in the Absolute ε DAC). A proprietary three-stage noise eradication circuit eliminating digital noise from the input signal. 
  • 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.
