Digital Streaming Quality - Important Notice:
The available digital audio stream depends on your device and operating system.

PS Audio's most affordable D to A Converter gives up little in the way of features from their larger and more expensive version, the DirectStream. Fully asynchronous on its inputs, the NuWave DSD can take just about any type of input, at sample rates and bit depths to match current high resolution standards and output pure analog through a class A hybrid output stage.
Like the DirectStream before it, the NuWave DSD produces a seamless 3D soundstage from even normal CDs. Hand-tuned and personally voiced by Paul McGowan, the improvement in sound quality over other DACs is astonishing.
All input signals are taken into the NuWave DSD in Native Mode without Sample Rate Conversion (SRC).
The input is a simplified FPGA known as CPLD (Complex Programmable Logic Device), which discovers sample rate and format. reclocks all incoming data, reduces jitter, waveshapes data output to the DAC chip, and utilizes high speed/low gate count logic to reduce propagation delay for faster throughput.
32-bit ESS Sabre Hyperstream
The DAC chip itself is the acclaimed 32-bit ESS Sabre Hyperstream architecture with an output that is passively filtered to reduce transient distortion.
NuWave DSD’s power supply includes a massive analog transformer, 7 regulators, properly-bypassed high-speed switching diodes, and a massive 15,000 mFd of storage capacitance.
The output stage is a unique Class-A configuration, fully balanced and direct coupled hybrid array (utilizing both discrete semiconductors and ICs), with an extended bandwidth of -3dB at 60 kHz.
The NuWave DSD allows you to stream bit perfect digital audio, both PCM and DSD, in a number of different ways, including music stored on your computer.
All incoming musical data are fed directly into a simplified FPGA in Native Mode, without the degradation typical of sample rate converter chips, common among DACs.
Native Mode decodes any resolution audio from 44.1kHz/16 bit all the way up to double rate DSD with no processing by an SRC.
The incoming data are identified, organized and prepared for proper delivery to the ESS Hyperstream DAC by the custom CPLD on the NuWave DSD’s input.
Asynchronous USB for PCM and DSD
The NuWave DSD features a high-resolution USB path based on the same XMOS technology found in the PS Audio DirectStream DAC.
Asynchronous and capable of 24 bit 192kHz performance for PCM and single or double rate DSD, the NuWave DSD USB input sounds every bit as good as the best digital audio is capable of.
The NuWave DSD accepts inputs from any digital source including I2S and USB from your computer and connects to your system’s preamplifier with either single ended (RCA) or balanced (XLR) connections.Used with any CD player or transport, the NuWave DSD produces a seamless three dimensional soundstage from your entire CD library. Connected to your computer, running music management software like iTunes, Bit Perfect, Amarra, or JRiver and an iPhone or Droid controller, the NWD becomes your center for streaming high resolution music at the touch of a finger. Performance as well as musicality are never compromised. Hand tuned and personally voiced by Paul McGowan, this fine audio instrument will bring the listener years of musical bliss.
For the first time in an affordable DAC from PS Audio, PS Audio has included an I2S input.
I2S is the native format of all CD transports and many servers.
I2S (pronounced I squared S) features separate clock and data signals from the source. Typically, these clock and data signals are multiplexed together to be transmitted over a single cable in a format known as S/PDIF (Sony Philips Digital Interface), or AES/EBU (Audio Engineering Society/European Broadcast Union).
Once received in multiplexed form, the DAC input must untangle the clock and data and once again separate them. I2S solves the problems associated with unravelling data of S/PDIF and AES/EBU formats. I2S outputs are sent via an HDMI cable and sources with I2S outputs can be purchased from PS Audio as well as other manufacturers.
Active vs. passive filtering
Once the digital audio data has been processed through the NuWave DSD’s ESS Hyperstream 32 bit DAC, it’s time to turn them into music; in comes the analog filter and output stage.
Most DACs use an active filtering system to clean up the output of the internal DAC but this can add a harsh, bright sound to the music. The NuWave DSD uses all passive analog filtering giving the output a sweet, open sound unencumbered with harsh digital artifacts.
