Rockna Audio Introduces the Wavedream Reference DAC: Redefining High-Fidelity Audio

 

Rockna Audio is proud to announce the launch of the Wavedream Reference, a groundbreaking Digital-to-Analog Converter (DAC) with network renderer, that sets a new standard in high-fidelity audio reproduction. Building upon a decade of innovation since the original Wavedream DAC, the Wavedream Reference embodies Rockna Audio’s commitment to excellence in engineering, design, and sound quality.

 

Each relevant component or subsystem of the Reference is defined by Rockna proprietary hardware and custom software. We accepted no limitations from off-the-shelf solutions like DAC chips, OEM streaming modules or signal op-amps. As always, we stayed true to our philosophy of presenting products with a high degree of originality and elegant technical solutions.

 

Innovative Hardware Architecture

At the core of the Wavedream Reference is a custom architecture designed for unparalleled precision and refinement. The DAC features a highly optimized AMD/ZYNQ chip for master control and network rendering, complemented by four Field-Programmable Gate Arrays (FPGAs) dedicated to each phase of the discrete conversion system. This sophisticated configuration ensures exceptional audio processing and signal integrity.

 

 

Advanced Clock System

Recognizing the critical role of clock systems in audio realism, Rockna Audio has developed an advanced, ASRC-free digital Phase-Locked Loop (PLL) clock solution for the Wavedream Reference. This innovation allows the DAC to perform with a natural sense of pace and rhythm, delivering an analog-like listening experience. By addressing issues such as jitter and signal imperfections, the Wavedream Reference preserves the fine nuances of the original recording.

 

Hybrid Power Supply

The Wavedream Reference boasts a meticulously engineered hybrid power supply, balancing efficiency and ultra-low noise to enhance DAC performance. With over 20 power-related circuits driving more than 90,000 µF of capacitance, and audio-grade toroidal transformers shielded by a thick copper sheet, the power supply ensures a clean and stable energy source for optimal audio fidelity.

 

Evolved DAC Modules

The D/A conversion stage features evolved versions of the acclaimed DAC modules from the classic Wavedream DAC. These complex modules employ a discrete sign-magnitude hybrid ladder topology, driven by sophisticated algorithms embedded in their own FPGAs. Capable of handling sample rates up to several MHz, the modules deliver unbuffered output for maximum transparency and natural sound reproduction.

 

Discrete Analog Output Stage

The final stage of the signal path is a fully discrete analog output stage, designed to work seamlessly with the new conversion modules. Combining JFET and bipolar devices in a Class A design, this high-speed buffer maintains low output impedance and minimal noise, ensuring full transparency and preserving the integrity of the audio signal.

 

Elegant Design and Layout

The Wavedream Reference features a 10-layer central core board for digital front-end processing and network rendering, with a symmetrical configuration of conversion boards to shorten clock and data signal paths. High-quality board-to-board connectors and internal shielding of transformers and displays further enhance signal integrity and reduce interference.

 

Network Renderer

The network renderer built inside Reference is unique not only because is our proprietary approach, but because it is seamlessly integrated into the DAC digital front-end. There is no separate “streamer section” or extra board, which removes the need for a dedicated external connection and unnecessary obstacles into the digital signal path. Natively integrated inside the Rockna ZYNQ SoC, the renderer can truly shine, allowing perfect sonic performance when selected.
