Absolute DAC ε

The new Ideon Audio Absolute DAC ε: the best sounding DAC today.

hi-fi+ Award


An Absolute revelation: bringing Music to life

  • With its future-proof modular construction, built to the highest standards, the Ideon Audio Absolute DAC encapsulates what is the state of the art in digital conversion, re-clocking, signal regeneration, internal and noise elimination, linear & non-linear distortion elimination, modular board isolation, and extreme components quality not often available elsewhere.
  • The heart of digital playback, transports you to the musical event itself.

HyperStream, 8-channels architecture

  • The highest performing DAC to date, sets a new benchmark for audio excellence with the industry’s highest dynamic range (DNR), up to 140dB, in a 32-bit, 8-channel DAC.
  • Unique 15ohm output impedance at -140dB SNR or 1W
  • Discreet power through 16 separate power regulators in the circuit. Direct coupled output with no capacitors in the output stage.
  • The finest details contained in the recording, come to the surface in a phase-correct manner, allowing the musical event to emerge complete.
  • The sonic result is no longer a lossy simulation requiring brainpower to cover for what is not there: you “are there”.

Proprietary Triple Distillation USB input: Noise Elimination

Conceived and designed in-house, the Ideon Audio Triple Distillation USB input comprises a proprietary three-stage noise eradication circuit that eliminates digital noise from the input signal.

Figuratively speaking, we have declared war on linear & non-linear distortion and noise!

Clock Oscillators: Getting the Music in Phase

The Absolute uses 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 Quad Analog Output Principle

The in-house deigned, Absolute DAC’s balanced output has four analogue output channels, no capacitors in the signal path and dedicated power supplies.

The output energy and strength can virtually drive any load!

Absolute choice, sounds at least 10 years into the future

The Absolute’s control board is fully isolated from anything else operating in the device. It has its own power supply line and discrete circuit.

Please note the transformer used to power the Absolute’s microcontroller & display: what we use for this light task, it is found used as the main power transformer in many well-known ultra-high grade devices!

What makes the Absolute your DAC of final choice well into future, is the absolute quality of sound whichever the format you are listening to.

It is supremely revelatory, intense, and relaxing; it excites, enthuses, and comforts, all in one: in the words of one reviewer, the Absolute “plays gorgeous music”.

You are consistently transported you to the encoded musical event!

Single-block, massive aluminium chassis

The 26kg (~58lb) CNC milled chassis takes 17 hours to complete. The result is a solid mechanical base housing the most intricate and expensive electronics available at this time. Various finishes are available to order.

Future proof – modular construction

Today, the Absolute DAC is state of the art in terms of design, construction and sonic performance.

Of course, if or when a new technology becomes available or a new format takes over, the Absolute’s modular construction ensures that it will be updated without fail.

Ideon’s Massive 17-Stage ultra-low noise power reservoir

Ideon’s massive multistage power reservoir comprises of 17 ultra-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 use six separate stages in order to achieve unparalleled clarity and linearity.

We choose top-level componentry: 17 state-of-the-art regulators with extreme low-tolerance rating, and over 80 audio-grade capacitors (ELNA Silmic II) with silk-fibre plate separators specifically designed for audio applications.

These components display higher propagation speed and low esr * resulting in smoother sound without loss of detail.

The sonic result is unparalleled restitution in clarity, midrange richness, musical energy, and dynamics. The music flows…

Absolute DAC ε – HiFi+

“…In short, the Absolute ε sets a new standard for reference DAC’s for me as the very best in almost every performance aspect…”  “…for someone seeking the musical whole will struggle to fi nd anything that comes remotely close to the Ideon Absolute ε…”

“…in the listening it was clear this was a world-class device capable of doing what so many high-end DACs claim to do, but often fail to achieve in reality; make music sound like music. Real living, breathing musicians playing in your living room. …This really is one of the best DACs in the world right now.”

Absolute DAC – The Absolute Sound

“…I found myself reveling in the best digital sound I’d ever heard from my system, by a wide margin.
..the fact remains that this is a world-class digital-to-analog converter, and even something of a bargain compared to its most elite competitors. There may be no sunroof or heated front seats, but Ideon’s Absolute DAC is a no-compromise piece of audio gear.
In a good way, which is why I’m buying one.”

Absolute DAC – Positive Feedback Brutus Award 2020

“…Power, authority, and presence-to-the-max…take my word for it.
The Absolute cast a real spell on me. There’s something quite seductive in its authoritative presence and ease that makes you lean back into your listening chair  and just take it all in…
…This is definitely a world-class design and execution…
…I can confidently award The Absolute DAC itself with one of my Brutus Awards for 2020. Truly delightful, this one.”

Absolute DAC, Absolute Stream, Absolute Time – High Fidelity

“…This is a top high-end, hence the GOLD FINGERPRINT award deserved for this system … …ABSOLUTE SUITE by Ideon Audio is one of the best-built audio I know… …the Greek player would be the equivalent of a top turntable ….”

” It is something between ‘weight’, ‘seriousness’ and ‘solidity’. It is the ultimate and certain force that you can always rely on and that does not change. And this is what the Ideon Audio sounded like.  It draws you into its world, both through the dense colors and saturation of the presentation with information, as well as through something that is difficult to define, and which makes us let go and listen to music in awe and delight.”
