Rockna Audio — CD Players / Transport
Wavedream NET
The ultimate fusion of high-performance music server and memory-based CD transport.
The Wavedream NET represents a masterclass in digital source architecture, serving as the definitive hub for both physical and high-resolution streaming collections. By integrating a high-performance music server with a cutting-edge memory-based CD transport, Rockna has created a singular, uncompromising machine that serves as the perfect companion to their reference-grade DACs.
At its heart lies a powerful FPGA-based audio core that streams data into a large RAM buffer, where it is meticulously clocked by an ultra-low phase noise master clock. This approach eliminates the inconsistencies often associated with traditional playback, effectively isolating the sensitive audio signal from the server's processing environment to ensure near-ideal delivery.
Rockna engineers have prioritised purity by utilising a dedicated linear power supply system, carefully balancing processing power to avoid the noise and thermal issues inherent in high-powered consumer CPUs. The result is a sound that possesses exceptional naturalness, rhythmic precision, and a holographic depth that breathes new life into every note, regardless of the source.
Whether spinning a compact disc or streaming via its Roon-ready network interface, the Wavedream NET maintains a level of digital integrity rarely achieved in a single chassis. It is a sophisticated, future-proof solution for the discerning audiophile who demands absolute sonic transparency and seamless control.
Key Features
01
FPGA-driven audio core
Uses a powerful FPGA engine to buffer audio data in RAM and re-clock it with an ultra-low phase noise master clock for jitter-free signal delivery.
02
Galvanic isolation
The embedded music server is galvanically isolated from the audio circuitry to prevent noise leakage and electromagnetic interference.
03
Linear-only power supply
Features a robust linear power supply for the entire unit, avoiding the high-frequency switching noise common in standard switch-mode power supplies.
04
HDLink I2S connectivity
Provides a high-bandwidth, direct digital connection to Wavedream and Wavelight DACs for the purest signal path possible.

Design & Philosophy
The Wavedream NET is built on the philosophy that a digital source should be as stable and predictable as an analogue instrument. By rejecting off-the-shelf network modules and noisy CPUs, Rockna has crafted a lightweight, Linux-based server that maintains sufficient power for multitasking without sacrificing audio purity. The integration of a memory-based CD transport further highlights their commitment to ensuring that every format, physical or digital, receives the same level of precise, isolated treatment.

Listening Notes
The Wavedream NET is designed to vanish from the signal chain. It produces a soundscape characterised by exceptional clarity, texture, and temporal accuracy, providing the DAC with an exceptionally clean digital stream. Listeners will notice an immediate improvement in soundstage depth and naturalness, particularly in the micro-details of acoustic instruments and the decay of vocal performances.
