The Ideon Audio Absolute Time Signature: boundless, digital signal restoration at reference level

Absolute Time Signature

Reference-level USB and SPDIF signal reproduction without compromise.
The Absolute Time Signature is an uncompromising design and implementation that solves all digital playback problems and delivers the ultimate quality signal for any DAC, regardless of price or brand.

Such a cleaned, newly generated signal is the first step towards a natural, powerful reproduction.

It was conceived, developed and manufactured as an ultra-high-end audiophile device, based exclusively on proprietary technologies developed by experts in software and hardware electronics through several years of research and development.

It works for both USB and SPDIF signals.

Evolution at the highest level

As a leader in re-clocking platform technology, Ideon Audio announced this new design in response to strong consumer demand for even higher standards in digital playback.

The Absolute Time Signature is the result of our extensive research and development work, our field testing and the experience we have cleaning and optimizing the USB signal with our proprietary re-clocking, re-generating and Re-Driving product family.

Using all this knowledge, design and components to an extreme scale, the Absolute Time is a bespoke product with a final artisanal touch.

Absolute Time Signature

3Rs.Address digital playback challenges.

The Absolute Time Signature is an extremely well-designed, precise and sophisticated audiophile device that re-clocks, re-excites and re-drives the digital signal, with corrections at both the input and output stages.

It's the only way to unlock the full potential of not just your DAC, but your entire audio system, eliminating noise, loss and jitter while dramatically improving dynamics, clarity and resolution, allowing you to pull the magic out of the numbers.

The signal quality is improved to an extreme level.

In addition, the proprietary Ideon Audio Triple Distillation USB input includes a proprietary three-stage noise reduction circuit that completely eliminates digital noise or any distortion from the input signal.

Additional features of the Signature Edition

  • The technology is an innovative combination of powerful design features and premium quality components, adding to the highly acclaimed existing Absolute Time:
  • Advanced triple distillation USB input with a proprietary three-stage noise reduction circuit that eliminates digital noise from the input signal.
  • Two cascaded sequential re-clocking systems featuring the absolute best femto clocks in a proprietary upgradeable circuit
  • Two sequential re-driving systems with clean performance and regenerative buffering technology
  • Parallelized ultra-low noise power supplies for noise reduction
  • Parallelized power transformers with overload
  • Future-proof, upgradeable platform
  • The Absolute Time Signature results in an extreme level of resolution and lifelike, natural sound with unimaginable dynamics and texture.This device will immediately reveal a clear and noticeable difference in ultimate audio systems.
  • The signature version shines with an exotic sound reproduction for customers who only expect the very best music experience from their system.

Two inputs and outputs (USB & SPDIF)

The Absolute Time Signature also features separate USB and SPDIF inputs and outputs - a boon for CD collectors looking to enjoy their music!

Absolute Time Signature

SPDIF correction / re-clocking

The Absolute Time Signature SPDIF circuitry also includes a stabilized coax input and a proprietary ultra-low noise, jitter-free re-clocking platform with a 12.8MHz master clock output.

Stability and performance

The Absolute Time Signature features electrically stable signal inputs and outputs; more importantly, it features a high-current 2.5A USB output (5V rail) capable of driving any load without loss of detail, clarity, or dynamics.

Extreme power supply in reclocking core

The Absolute Time Signature uses huge, extremely high-current, extremely low-noise, linear power supplies - a "trademark" of Ideon Audio.We've equipped the Absolute Time Signature with a huge main power supply comprised of select audiophile-grade, low-noise silk caps.

The Absolute Time Signature is the only reclocker today that uses two parallel, audiophile-quality, high-performance transformers that are highly resilient for the application and are handcrafted.

Plenty of clean energy

As with all Ideon devices, the power supply is carefully rectified and regulated to ensure vanishingly low noise and distortion.

In the Absolute Time Signature, we built a three-stage, ultra-stabilized filter that feeds the circuit.

This approach is critical to the sound quality you are aiming for: vivid, real and dynamic that connects you to the music happening.

Future proof phase correction

Proper timing is what Absolute Time is all about! We apply the correction to both ends (input-output) of the circuit.

Solid, single-block aluminum chassis

It takes 15 hours to complete the 22 kg CNC machined chassis.

The result is a solid mechanical base that houses the most complicated and expensive electronics currently available.

Different finishes are available to order.


  • Separate, electrically stable USB and coaxial (SPDIF) inputs
  • Generously dimensioned power bank, 2 x handcrafted audiophile transformer
  • Linear, three-stage, ultra-low-noise, stabilized power supply with separate leads to various circuits.
  • Low ESR audiophile (silk) capacitors throughout;
  • Proprietary 2 x cascading femto-clock re-clocking circuitry on an upgradeable platform;
  • Phase-correct restitution and negligible jitter.
  • Proprietary noise-free rectification bridge eliminates diode rectification noise
  • USB output: ultra-stabilized with signal amplification, high power (2.5S / 5V rail), easily drives any load
  • SPDIF output: proprietary PLL with ultra-low noise and jitter mitigation / supports 12.8MHz master clock

"...I've never seen anything like it - fascinating..."

“…incredible resolution and three-dimensional sonority, which is particularly surprising in the high pitches…””This is great class and for me absolutely unique, very far from the usual…”

“…The Absolute Epsilon DAC, Absolute Stream music server, and Absolute Time master clock are in the upper echelon of today’s best digital playback.The trio has some remarkable musical attributes, including stunningly lifelike reproduction of music's dynamics.The sense of immediacy and presence—the impression of nothing between you and the music—was equally impressive."

”…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.”
