Delivery time approx. 2 weeks.
The IRIS is our entry-level USB digital-to-digital converter. DENAFRIPS has spent three years intensively refining it, leveraging the advances inherent in our renowned DAC.
These advancements include DENAFRIPS' exclusive FPGA DSP processing, FIFO buffer and reclocking technologies, and an exceptional USB audio interface solution via the advanced AMR-based STM32F466 MCU.
Celebrating DENAFRIPS' 12th anniversary and exceptional expertise in digital audio, the Iris 12th Anniversary Edition features the coveted sound quality of the original Iris along with performance enhancements.
WHAT IS A “DDC”?

A DDC, which stands for digital-to-digital converter, is a device that converts a digital audio signal from one format or interface to another within the digital domain. Its primary purpose is to facilitate harmony between different audio systems, especially when faced with different digital interfaces.
The Denafrips Digital-to-Digital Converter (DDC) is a device carefully designed to accept a digital audio signal into a specific digital connection, such as USB, and then convert it to alternative digital audio outputs. This conversion process not only improves audio quality but also involves the application of advanced processing techniques.
Denafrip's DDC uses a FIFO buffer to store and manage the incoming digital input signal. This buffering process is enhanced and reclocked using an internal high-quality femto-clock, ensuring precise timing and synchronization. Furthermore, the DDC features galvanic isolation, protecting the signal from electrical interference and maintaining signal integrity throughout the conversion process.
Denafrips has earned a reputation for manufacturing DDCs that deliver outstanding audio performance. This is achieved by integrating cutting-edge technologies that ensure precise signal conversion and preserve the authenticity of audio data during enhancement. These DDCs serve as a vital link in connecting disparate digital audio setups, promoting compatibility between different audio components that may use different digital interfaces or have different sampling rates.
The 12th Anniversary Edition

A combination of 8 sets of precision linear regulators with extremely low noise levels, coupled with an oversized 60 VA UPOCC copper O-core transformer, efficiently supplies the digital circuits with clean power.
The incoming USB digital signal stream is buffered in a FIFO and then reclocked using the FEMTO crystal oscillator. This careful process significantly minimizes jitter and ensures that the resulting digital output signal is free from disruptive jitter noise.

Iris 12th features an improvement in the form of a 60 VA O-core shielded transformer. This transformer is carefully manufactured in-house by DENAFRIPS engineers using UPOCC copper.
The oversized 60VA O-Core shielded transformer delivers significant power to the Iris 12th DDC's multi-stage linear power supply. This upgrade ensures the Iris receives a plentiful and stable power supply for optimal performance.

FEATURED REVIEWS

Denafrips has engineered a first class iteration
In all my listening, the main benefits of the Iris became very clear: image coherence and inky black backgrounds. Whatever tonal tendencies your individual DAC may possess, the Iris will likely not alter them, but it can definitely be a non-subtle upgrade in terms of focus and noise.

In each case, there was a clear, Are we clear? Crystal, improvement in sound quality when the Denafripps IRIS was in the system doing its thing, as compared to going straight out of the Pi via USB. While these sonic improvements varied in terms of degree according to the DAC, better was simply better in every case.
