Cutting Edge DAC with Vacuum Tube Preamp
The Grand Pre from Peachtree Audio combines a high-quality, high-resolution DAC with a true state-of-the-art hybrid tube preamp. Both analog and digital sources will sound exceptional, and the addition of balanced inputs and outputs will make it a perfect fit with the best sources and amplifiers you can find. This helps make the Grand Pre a full-featured state-of-the-art control center that's designed for the modern day music listener while also satisfying the purists who love the rich, luxurious sound of vacuum tubes, recalling the Golden Age of hi-fi.
If you want to achieve the highest possible resolution for computer audio, streaming audio devices, or even your CD player, the Grand Pre will take those devices to a reference level of audio reproduction. When faced with the extremes of bad power supplies, grounding issues, and high jitter, most preamps and DACs fail to deliver maximum performance. The Grand Pre, on the other hand, was developed with these unique problems in mind.
Tubes Rejuvenates Compressed Music Sources
The reference-quality Grand Pre preamp routes all of the information from the DAC through a short signal path that uses gain control and discreet 'Class A' output stages. The Bascom King tube buffer circuit uses the musically legendary 12AX7 tubes and is designed to rejuvenate average recordings and compressed music sources like Pandora and Spotify. Like Peachtree Audio's extremely popular Nova and iDecco, the Grand Pre can be used in pure solid-state or hybrid tube mode.
Reference ESS Sabre32 DAC
The digital heart of the Grand Pre is a highly evolved reference ESS Sabre32 DAC. This sophisticated chipset knocks jitter down to <1 picosecond for accurate sound reproduction. Furthering the sonic purity, the Grand Pre uses galvanic isolation to eliminate noise generated by switching power supplies in source components. Peachtree Audio thought of everything. Even the volume control is special. The Grand Pre has a VCA gain control for minimal noise and crosstalk in place of the potentiometer that's commonly used by other manufacturers.
The Ins and Outs
The Grand Pre marries its advanced circuitry to plenty of connectivity. It includes two coaxial digital inputs, two optical digital inputs, and even a BNC digital input. Peachtree's new asynchronous I2S 24-bit/192 kHz USB input provides the best connection between computer and DAC. And because the Grand Pre isn't just for digital enthusiasts, it also includes two single-ended RCA analog inputs and a balanced XLR analog input. On the output side, it includes a line out, and high-pass preamp out, a standard single-ended RCA preamp out, and a balanced XLR preamp out.
The convenient Home Theater Bypass makes it especially easy to integrate the Grand Pre to a home theater amp. It allows you to use the amplifier connected to the Grand Pre for stereo use and for the front left and right speakers in your home theater.
Last but far from least, the Grand Pre includes a well-thought-out dedicated headphone stage. It's so good, you may never remove your favorite pair of 'phones. And for late-night listening, double tap your currently active input button to dim all of the LEDs on the Grand Pre's faceplate.
Peachtree Products are solid and reliable. They're built for years of trouble-free enjoyment. A high performance product inside and out, the Grand Pre's aluminum faceplate is over 1/2" thick, has titanium buttons, and weighs a healthy 24 pounds.
