The Peachtree Audio preDAC is a preamplifier + DAC based on the incredible nova500 integrated amplifier. The preDAC is, in essence, a nova500 with the amplifier section removed - but with key upgrades. Like the nova500, the preDAC is a differential (aka balanced) audio design that provides exceptional immunity from noise/interference and keeps the audio signal as far above the noise floor as possible. The preDAC features a dedicated power supply, superior signal-to-noise ratio, balanced XLR outputs (in addition to single-ended RCA) and even better headphone amp performance. The preDAC provides the same input flexibility as our nova integrateds: USB-B for a computer USB-A for an iOS device coaxial digital 2 optical digital 2 configurable analog inputs including MM phono Home Theater Bypass LOOP feature to insert equalization, room correction, or other signal processing into the signal chain We can’t think of a better partner for the preDAC than the Peachtree amp500 - but perhaps you have a class-A or tube power amplifier that you love, but want a contemporary front-end to pair with it. We have the solution! Insert the preDAC into the system and add all the input capability and sound quality that the balanced preamplifier section and world-class ESS PRO DAC provide. Want to bi-amplify your state-of-the-art loudspeakers? Send the preDAC's output to two amp500s and experience the enveloping sound and effortless power your speakers are capable of - all at a modest investment by esoteric audio standards!
