PS Audio Perfect Wave DirectStream DAC
Beschrijving / Description
Product of the year
PS Audio's DirectStream DAC gets a 'Product of the Year' award from almost all major reviewers. For once, all reviewers agree and that is quite unique. Maybe you should listen too.
DirectStream DAC
Once again, PS Audio pioneers a totally new approach to the playback of digital (PCM) files, whether from CD or from files on a server, with the new PerfectWave DirectStream DAC. Hand-written, discrete and perfection-based Delta Sigma conversion, a new groundbreaking technology that sets itself apart from any 'cost-no-object' product on the market today and offers a significant added value for the serious music lover and/or audiophile.
The Next Generation
The PerfectWave DirectStream DAC is fully DSD based, even for PCM inputs. DSD was chosen for its simplicity, linearity, common architecture, immunity to cable and input differences and last but not least, its ability to bring out the subtle musical details previously buried in digital media, masked by classic PCM decoding techniques.
The DirectStream DAC is one of the few high-end products that completely overcomes the limitations of traditional digital to analog converters (DACs) by its uncompromising performance, no matter what medium delivers the data, be it a CD player, a hard disk, a computer, a network or the Internet.
A complete solution
The DirectStream DAC is a complete solution that can be used in a variety of ways. As a stand-alone DAC, the DirectStream DAC accepts input from a digitally connected source, such as a CD player, CD transport, digital TV receiver, music server or computer. With the (optional) network bridge, the DirectStream DAC acts as a music server and can access any DNLA compatible network, such as a NAS, computer and can even stream music directly from the internet.
As a preamplifier, or control center, the DirectStream DAC can be connected directly to a power amplifier, with the volume and balance controls and the input selector that allows you to choose one of the seven digital inputs, you can fully control it with an iPad, iPhone or iPod, without even leaving your listening chair.
Asynchronous Inputs
The DirectStream DAC has 7 asynchronous digital inputs, including two I²S over HDMI, one optical TOSLINK, one coaxial S/PDIF, one balanced AES/EBU, one 192kHz 24 bit USB input and the optional Network Bridge.
The HDMI inputs are not capable of accepting HDMI data, but instead use a unique PS Audio developed standard for I²S data (the original data management system inside every transport, CD player and DAC) to transfer data from the PerfectWave memory player to the DAC in the best possible way.
The PerfectWave Bridge
If you want to play music stored on your computer through the DirectStream DAC, the asynchronous 192kHz 24 bit USB input offers you an easy and convenient solution.
However, if you prefer not to use a computer or you want to keep your computer separate from your audio system, you can use the optional Network Bridge, which allows you to stream audio via your home network.
The PerfectWave Bridge is a strong piece of technology. It connects all your digital music sources in your home through your home network. The Bridge ensures a bit perfect performance of your music and this for every sample rate up to 192 kHz, 32 bit audio and brings uncompromising music to your high-end audio system.
