The PerfectWave Bridge is the most important product PS Audio has ever designed! Likely to change the world of high-end audio, the Bridge creates a connection between one of the world's best sounding DACs and the music on your computers and your network. Once connected, the Bridge allows the uncompromised flow of music on your computer directly to your audio system.
Bridging the Gap
There are many streaming audio solutions, but none that are built with a true high performance audiophile sensibility. The majority of the few connected audio streaming devices on the market today are based on either a small PC type motherboard or off-the-shelf microprocessor based solutions with integrated clocks and little to no control over the way the data is handled and manipulated. With very few exceptions, these solutions do not come close to the performance of the PS Audio Bridge. The Bridge is unlike anything ever built to date. The Bridge is a true asynchronous parallel 32 bit system approach. There are actually two low jitter isolated and separate clocks (44.1kHz and 48kHz) completely unrelated to any other clock in the Bridge creating true asynchronous performance.
Clear The Bridge
There is also no digital manipulation of any kind going on in the Bridge, either through sample rate converters or DSPs whatsoever. Many systems rely on system wide clocking and digital manipulation to lower jitter and improve performance, only the PS Bridge has a real Digital Lens built in, providing low jitter I2S music without any digital manipulation and the differences are easy to hear; this combo is simply stunning.
Crossing the Bridge
With the Bridge installed, the PerfectWave DAC becomes a state-of-the-art, no compromise, music server controlled by both its front panel touch screen as well as PS Audio’s iPhone app. Music stored on your hard drive, NAS drive or computer can finally be streamed to your high end audio system without reduction in sound quality. The Bridge changes everything and is a must-have addition to the PerfectWave DAC. The Bridge, coupled with the great user interface of the PWD, will revolutionize the way you listen to music.
The Bridge will play just about any format of encoded music ever designed; lossless or lossy, high resolution or standard resolution. FLAC, ALAC, WAV, AIFF, MP3, OGG, APE the alphabet soup of formats is dizzying. The only thing the Bridge will not play is SACD because of digital rights problems with Sony who will not permit SACD to be copied onto a hard drive and stream the results.
Building A Bridge
The Bridge has been in the works for over two years and represents the single biggest engineering project ever tackled by the PS Engineering staff. The work was completed by a team of 15 engineers, programmers and coders located in Russia, Rhode Island, Cupertino and Boulder. This was truly a world-wide effort of some of the brightest people in the industry and a monumental achievement for PS Audio.
The Bridge is based on 32 bit technology with the core processor running at 500mHz and uses 256mB of high speed DDR memory for the Lens. Data is clocked out of DDR memory into a custom CPLD (Complex Programmable Logic Device) that organizes each of the 32 bit frames into the requisite I2S format. The I2S data is then clocked out of the CPLD with one of two custom, low jitter, fixed frequency asynchronous clocks (depending on the sample rate) and finally leaves the Bridge and into the PWD through high speed buffers powered by a separate supply in the PWD.
Installing The Bridge
The Bridge is plug and play and installation couldn't be easier. Power off and unplug the PWD. Remove the expansion panel from the rear of the PWD and slide the Bridge in. Insert the included SD card into the SD slot, plug the PWD back in and the Bridge is ready to go. Connect the Bridge to your network via Cat5 or Cat6 cable and the controller will “see” the bridge and allow you to connect to it with the touch of a button. It’s just that simple.
Controlling the Bridge
The Bridge can be controlled either via the front panel or remote control via Apple's iPod Touch, iPhone or iPad. You'll need to download the PS Audio app via the iTunes store. Using the app couldn’t be easier. Cover art and artist’s bio are sent over from PS Audio's servers automatically as long as your network is connected to the internet. Everything just happens without anything required from you, the user. Scroll through the library, find something you want to hear and simply touch the song title. The system immediately begins to play, setting the correct sample rate and filter setting automatically.
