High-Resolution Digital Audio
Bring your preamplifier, receiver or integrated amplifier into the computer age with the Peachtree Audio iDac. The iDac is a stand-alone digital-to-analog converter featuring a PURE DIGITAL iPod dock, which delivers the "1's and 0's" from your iPod directly to the iDac's own internal DAC. The iDac has four additional high-resolution digital inputs for your computer, Apple TV, cable box, Sonos or any other digital source. You’ll hear the difference instantly and the improvement is guaranteed to be nothing less than startling!
Lightning-connector iOS devices compatible with adapter: 
An adapter available directly from Apple allows you to connect a Lightning-equipped iOS device to the iDac's built-in dock.
Design
Special Digital to Analog Converter
The heart of the iDac - what propels the iPod and other digital sources to a new level - is our all new ESS 32 bit Sabre32 digital-to-analog converter. It’s engineered for real-world sources that often deliver a high-jitter signal: computers, iPods, cable boxes, Apple TV, Sonos, etc. Almost anything digital. The iDac will also improve the digital output from most any standard CD or DVD player. Most DACs on the market were developed to handle low-jitter signals, the digital output of a good CD player, for example, but are poorly suited for computer audio. When faced with the extremes of streaming, bad power supplies, grounding issues and high jitter, they almost all fail to deliver maximum performance.
Engineered for a difficult environment
The iDac, on the other hand, was developed with precisely these extremes in mind. Our design uses a mutli-layer DAC board with over 450 components, a linear power supply and 11 regulated subpower supplies - preventing noise and distortion at every level.
The ESS Sabre32 DAC’s patented jitter-reduction circuit re-clocks the digital signal before passing it through a high-resolution 24bit/192kHz bit-perfect processor. Re-clocking is needed for computers and most streaming or hard-drive based music servers because most have high levels of jitter and/or noise. Noise, typically associated with ground problems and switching power supplies, is eliminated by transformer-coupling each digital input. The USB connection is galvanically isolated, eliminating noise generated by your computer’s switching power supply and greatly improving sound quality.
PURE DIGITAL iPod dock
Virtually all iPod docks today pass only the "analog" signal from your iPod. Not so with the iDac! The iDac sends the digital "1's and 0's" from your iPod directly to its own internal high performance DAC. That's why we call it PURE DIGITAL. And that's how your iPod - plus the iDac - produces sound to rival a high-end audiophile CD player.
How do you like your sound?
The iDac's switchable digital filters let you tailor your music to your taste! The NOS/NAL button chooses between "no oversampling" (NOS) or "non-aliasing" (NAL). Steep filter slopes don't sound particularly good. But a DAC using a gentle filter slope - like the iDac - is susceptible to filtering aliasing distortion. The iDac uses sample rates of 96kHz or 192kHz to partially attenuate this aliasing. And Peachtree has developed software to eliminate aliasing distortion in the sampling process. Many critical listeners will prefer the sound of the NOS setting, even though the NAL setting measures better. Let your ears guide you - there is no "wrong" setting! The Hi-Bit/Lo-Bit switch configures the individual switching elements of the iDac's Sabre32 DAC. Sonically, Hi-Bit moves voices forward a bit; Lo-Bit offers a more laid back perspective. Choose Hi-Bit or Lo-Bit according to your listening preferences.
Video
The iDac includes both component and S–video outputs. Place your iPod into the dock and watch TV shows, movies and YouTube all on your HDTV. Or gather round after a big day and watch the HD movies you’ve created on the fly with your new iPod touch. Add just the right playlist for atmosphere and enjoy home movies like never before!

iDac Reviews
"With their uniquely rounded case-work, solid and hefty feel, high quality of fit, and glossy finishes, Peachtree Audio components are easy to spot, and the iDac is no exception - it's so lovely, rounded, and inviting that I can imagine using it as an audiophile pillow." Read the full review . . .
"The sound that an iDac can pull from even a 320bps MP3 file on an iPod is pretty amazing. But with non-lossy 16/44, 96/24, and 192/24 music files coming in through its S/PDIF inputs, the iDac demonstrates its full sonic potential. This is one sonically serious DAC whose performance transcends its name." Read the full review . . .
