ROCKNA Wavedream NET
-
Detail
Local, LAN and disc memory transport
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.
FPGA-based high performance audio
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.
Isolated music server
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.
Linear-only power supply
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.
Software features
The WDNET software pack is a dynamic collection of audio services. They are controlled over a simple and straightforward web interface which can be accessed from the phone/tablet or a local computer. Currently following services are supported
- Roon Server – recommended control app: Roon remote
- MPD Server – recommended control app: MPD control, MPDroid
- Upnp/DLNA
- Airplay
- HQplayer NAA
- Disc ripping – FLAC, WAV, MP3 on local storage
