Product Description

PS Audio DirectStream DAC and streamer introduces near perfection to your digital media up-sampling. All digital inputs, including PCM are converted into pure DSD and with a simplified processor the DirectStream DAC is able to reveal the finest musical details from your digital audio recordings.


The DirectStream DAC is like no other. It has been designed to ensure your music collections can be heard with the finest details as if you were there in the recording studio yourself. It does this by taking a pure DSD approach for both PCM and DSD media unlike traditional PCM based DACS.

Pure 100% single bit DSD based D to A Converter

Even some of the best DACs out there are not able to produce the best sonic results. This is due to their one-chip architecture. Differing to this, the DirectStream upsamples both PCM and DSD into single-bit DSD and delivers pure music. This design means regardless of the input format, musical information is presented in optimum quality.

CD Revival

The new processing method means that details that have been hidden for years in PCM audio files can now be uncovered. PCM is how CD's are recorded, but decoding PCM can be complex and may mask subtle details in the music. The path to quality musical retrieval is exceptionally simple with the DirectStream, CD's receive a new lease of life, with increased linearity and less edge.

Passive Output Stage

PS Audio DirectStream DAC takes a passive approach with its output stage. The execution of the output stage is impressively elegant and simplistic, whilst ensuring musical accuracy. A high performance passive audio output transformer is fed by high-speed class A video amplifiers. What follows is a low noise, low distortion output signal that ensures a clean, pure reproduction of music from the DirectStream.

Resolution Perfect Volume and Balance Controls

100% bit-perfect volume and balance controls ensure no loss of resolution and output level control even when fed directly into a pre-amp or power amp. This is a rare feature for DAC's, making the DirectStream an even more impressive performer.

One Low Jitter Master Clock

One master clock allows for a simple, direct signal path unlike typical high-spec DACs that use separate clocks that require complicated synchronization. This DAC and Streamer uses a low phase noise, low jitter clock designed by Crystek especially for this model. It ensures jitter levels are reduced and music is delivered with an amazingly quiet background and with stunning clarity.

Asynchronous high-speed USB

Connect the DirectStream to your computer directly with a high-speed USB connection. It offers a fully asynchronous 24-bit 192kHz path for USB based audio, and along with a high quality USB cable like a MAC Mini, you an control music through your iPhones and  iPods with ease. Android is also available with a third party controller program.

Polarity Phase Control

Polarity phase control feature available on both the touch screen and remote allows userts to select normal or inverted phase for every digital input or CD. You can switch to the correct polarity when activating the input if the disc is wrongly inverted. Being able to easily fix the phase on your recordings means you can can hear each piece of music as realistic and emotive as they were created to be.

Optional Network Bridge II

To further enhance your DirectStream you can add the Network Bridge II which allows you to add MQA and Tidal. Please select whether you would like to include the optional Network Bridge II.
