In our quest for developing a package for the audiophile seeking more than just high-quality audio reproduction, we realized several things. Firstly, we need digital precision but with „analog” charm, free of any „digital glare” yet with rich detail. Secondly, this package needs to provide outstanding value, future proofing, new features and a stunning, timeless design. This is how the „Wavelight DAC” was created, more than just a little brother for the accomplished „Wavedream”.



For the Wavelight we truly did our math and extended out testing methodology. Careful optimizations allowed us to achieve subtle nuances in listening sessions so that any listener is catered for.

Powerful, customized DSP units are performing high precision calculations in real time for studio-quality upsampling. User can choose between 4 filter modes : linear, minimum phase, hybrid mode and NOS.


A combination between memory buffers, digital phase-locked-loop (DPLL) and a custom input clock-decoupling scheme provides effective jitter cleaning before the conversion itself. Using the advanced Femtovox2 technique, the final result will lead to an „analog” sound without compromises.

A high precision R2R discrete ladder is performing the conversion from digital to analog domain, driven by the FPGA algorithms. The Wavelight dac is capable of operating in pure R2R mode or in a Hybrid mode ladder*. Future firmware will allow the switch at the touch of a button.

*currently in development


With 5 digital inputs and one analogue input, the unit is also capable of operating as a preamplifier. To avoid data truncation, the volume control inside the Wavelight is fully analogue, even if controlled digitally.

The analog path is fully discrete. Two toroidal power transformers allow the separation between analog and digital circuitry. A massive filtering bank capacity (over 100.000 uF) is conditioning the power supplies.


Each Wavelight is manually assembled in Rockna factory, individually tested and undergoes our strict quality control process. We believe that sound should be complemented by detail in fit and finish, sturdy construction, thorough circuit design and reliability.

This is why we are using selected components such as high precision resistors or audiophile-grade decoupling capacitors. The chassis is entirely built from massive aluminium with anodised finishing and a fine brushed texture.


The Wavelight audiophile music Server – or the WLS – is your perfect source partner for Wavelight/Wavedream dacs, or just any dac, especially if equipped with a I2S input. In adition the I2S output, USB, AES/EBU, SPDIF, and optical output (Toslink) are available.


WLS resolves a few important aspects of a modern audio setup. It virtually eliminates the need for a computer holding your core server; will eliminate the need for a strong CPU to perform PCM to DSD transcoding; and eliminate the need for a storage server. All these features are included into a sleek and stylish package, visually matching the Wavelight DAC.





The WLS combines a few key elements for server-based digital audio playback: a linear power supply, a low TDP computing system running custom Linux, a highly efficient FPGA / DSP system for audio management.


The WLS will manage to transcode between formats on hardware level, without overloading the CPU. Therefore, it’s heat and RFI emissions will stay low, without bad influence on audio circuitry.

The WLS has the ability to let you choose from a variety of server software and audio services including Roon, MPD, LMS and so on. There are many use scenarios, the device can be used as core, or can be used as renderer or endpoint.


Wavelight Server was designed to host your music. From a basic 2TB to a maximum of 16TB of internal storage, it can keep internally thousands of music albums in high-quality, uncompressed format. Additionally, WLS has 3 USB ports, where you can connect external storage, and/or a NAS (Network Attached Storage) can be defined as music source for WLS.





The WLS has a powerful control interface that can be accessed via local browser or control app. It allows the owner to manage internal or attached storage, select active software or services, select upsampling or transcoding parameters, select I2S output setting for DAC compatibilty, rip cd’s to local drives, enable room correction etc.

WLS is fully upgradable and future-proof. Both operating system with services and FPGA (audio hardware) can be easily updatable via internet.







We are proud to present our current flagship in digital audio reproduction. We believe it has the right ingredients to produce a sound that will honour it’s name. In the good tradition established by it’s predecessor, the Wavedream continues to push the limits of performance, design and sound quality. The ingredients, innovations, technology and features of the product are presented below.



We always thought that high-end audio should be everything about innovation. Playing around with off-the-shelf available chips is fun and certainly a good and economic way to produce good sound. But once you want to design a cutting-edge product, the off-the-shelf approach doesn’t apply. Naturally, a custom solution, freed from the limitation of the available chipsets, come into place, allowing us to design and build from the scratch an entire digital audio system.

All building blocks of the Wavedream DAC concernig digital processing are built entirely on a single piece of programmable silicon – a FPGA . With a FPGA, it’s internal hardware architecture could be described by a piece of software (actually, a very complex one). When upgrading the Wavedream with new firmware, you actually change it’s hardware. This system allows great flexibility, obsolescence protection and let us improve the sound of your dac by changing it’s internal architecture, or add new cool features, or improve the existing ones.


The clock is the heart of a digital reproduction system. It’s accuracy and jitter levels are critical in regard of sound quality. Only a very good clock system can make the way to the analog sound on the output of your DAC. If the clock is flawed, digital harshness will occur and the analog feeling of the music will be severely altered. Apart from the performance of the clock itself, equally critical is the construction of the clock tree (the clock distribution architecture) inside the DAC. The jitter amount that really counts it’s not only the performance of the clock itself – but the clock which actually enters the dac and is used for conversion – let’s call it the conversion clock. The conversion clock that enters the dac section relies on the clock tree, which is usually not just routing, but in most cases conditioning, altering it’s quality. A poorly designed clock tree can degrade significantly the clock quality entering the d/a section, even if the source clock has great performance.

With these facts in mind, we designed for the Wavedream an advanced clock system called the femtovox. With femtovox in place, one is assured that only extremely small amounts of jitter are present at the dac conversion clock input. It’s unique architecture employs that conversion clock is directly synthesised at the dac input, without any conditioning, giving constant jitter performance at any sample rate. The conversion clock is controlled with 1 ppb precision, while exhibiting about 300 fS of jitter. The smallest jitter figure in the world? No. The smallest jitter figure where actually matters? Probably.


The Wavedream upsamples any material with a fixed rate of 16x. The dac modules will decode the digital stream with a rate of 768Khz, or 705.6Khz, respectively, according to input sample rate. We found this rate to be optimal for analog performance of the dac modules. Behind this simple multiplication factor (16x) lies a huge processing power. The digital filters are made with the combined effort of 58 DSP blocks, resulting into a impressive figure of 15 GMACS of processing power.

The developed filters are unique. We avoided standard Nyquist rate filters as not providing the expected performance for the dac. After lots of mathematical simulations and careful listening tests, we have created a custom Parks-McClellan upsampling filter. There are three variations avaialble on current firmware: linear, minimumand hybrid phase. They are highly optimized filters, offering stunning performance with a large number of taps (5k), and they are different in regard of impulse response. For the linear phase, the ringing energy (Gibb’s overshoot) is equally split before and after impulse. Minimum phase type shows all this energy after impulse, while our special hyrid phase filter has a combined response between linear and minimum, exhibing very low overshoot before the impulse.


For the effective D/A conversion stage we developed dedicated dac modules called RD-0 (used in Signature – 27 bit structure) and RD-1 (used in Edition – 26 bit structure). Modules themselves are complex pieces of technology, sharing a discrete sign-magnitude hybrid ladder topology, driven by a complex algorythm which is embedded into their own FPGA. Therefore the dac modules firmware is updatable both performance and feature-wise. Currently RD-0/1 can sustain a maximum sample rate of 6 MHz, which is the industry’s maximum sample rate specified for a audio dac. The output of the dac modules is un-buffered, allowing maximum transparency and natural sound reproduction.



Finally, the last stage of the signal path is the analog output stage. It’s contribution to final sound is of extreme importance. Designed from the scratch to work with converter modules RD-0 & RD-1, the output stage is totally discrete and acts as a high-speed buffer. Made entirely with through-hole components (non-smd), we combined j-fet & bipolar devices into a class A design, with a closed-loop output impedance of under 1 ohm and equivalent input noise as low as 1nV, as a perfect match for the converter overall performance.


Naturally we have dedicated sections for digital and analog areas. There are 3 separate transformers, and all power supplies are low noise linear – no switchmode power supplies are used whatsoever. There are a total of 20 linear regulators inside the dac. We dedicated our attention to the dac modules regulators – which are designed from the scratch for low impedance and ultra-low noise.



The Wavedream benefits internally from a carefully studied, full symmetrical layout. Shortest signal paths and proper design of the clock tree were our main guidelines. All off-board connections are made with LVDS standard for lowest intereference, high speed and minimal jitter.

The transformer section is internally shielded to prevent internal EMI leakage. The chassis is entirely made of black anodized aluminium with a maximum fronplate thickness of 20 mm. Switches are black ruthenium finish.



The Wavedream NET is a unique product which adds together a high performance audio server and a latest generation, memory-based cd transport. You can enjoy your cd collection, internal storage playback or latest streaming experience from only one machine. The NET is naturally the best complementary source for the Wavedream DAC over the HDlink(I2S) connection.


The NET is built around a powerful digital audio core, which streams all audio data into a large RAM buffer. The audio data is clocked out after a ultra-low phase noise masterclock, making the machine close to a ideal source. The powerful FPGA engine takes care in exclusive mode of the disc playback, which is totally separated by the server side. Also, the FPGA contain a large number of DSP units which can be very effective in real-time processing of audio streams, saving lots of processing power from the server’s side CPU.


The audio server embedded into the NET is galvanically isolated from the audio side to prevent any kind of unwanted noise to leak into sensitive areas. We carefully balanced the server power consumption with it’s processing power. A very large processing power means more complex and power-hungry CPU’s, which are not necessarily a good thing for audio reproduction. The server software is based on a lightweight version of Linux, which gives our quad-core processor enough headroom to run many audio services in parallel.



One of our design goals was to stay away from a switch-mode power supply, which can have potentially higher noise and possible harmful effects when placed near sensitive audio circuitry. Therefore, there are only linear power supplies inside the NET, including power for the server side. At first sight one might be tempted to use high-powered CPU, following the principle “the bigger, the better”. Actually, a large processing power is not always necessary and it comes with benefits of lower noise, simpler architecture, lower radiated EMI and of course, lower power consumption.
