There is a newer model of this amplifier available: Peachtree Audio nova125 Amplifier
A New Milestone
Peachtree Audio has raised the bar with the Nova.
Consider the Nova if you’re looking to improve your computer-based or streaming audio to a “high-end” performance level. The Nova is a world class 80 watt per channel integrated amplifier with a built-in high-performance digital-to-analog converter. It has enough digital and analog inputs and outputs to satisfy all the new digital devices. Plus, it can handle the oldies like turntables (with an external phono preamp), tuners, etc. The Nova performs like a high-end integrated amplifier - because that’s what it is. We call it the "new millennium" integrated amplifier!
Whether it’s digital or analog, the Nova is engineered for the way you listen today.
Digital to Analog Converter
Critical to the performance of the Nova is the onboard ESS 9006 Sabre DAC. It’s a 24bit/96kHz upsampling digital-to-analog converter, which transforms just about any digital source to the performance of a high-end CD player. The Sabre DAC’s patented jitter reduction circuit re-clocks the digital signal to nearly zero jitter before passing it through the high-resolution 24/96 upsampling processor that’s also capable of 122dB s/n ratio. But the DAC chip is only part of the story because the surrounding electronics are extremely important. We employ 11 regulated power supplies for the DAC. We transformer-couple each digital input stage so noise associated with ground problems and switching power supplies is eliminated. The USB input is unique. It is galvanically isolated from the computer connection. This is critically important because significant noise generated by the computer’s switching power supply travels down the USB ground and manifests itself as a major source of jitter. We eliminate it before the DAC even sees it!
The Tube Preamplifier
The preamplifier is one of the most important components in any system and often determines the way your system sounds overall. It must handle all of the switching and volume tracking. All of your music travels through the entire circuit before getting to the amplifier. So attention to detail is key if your goal is faithful reproduction. Even though there's an 80wpc amplifier on board, the Nova is unique because we designed the preamp circuit to be a stand alone preamp.
The Sound: The Nova preamp section uses a 6922 tube with a class A output stage. Why? Because we love the sound! This is where art meets science and there's a certain magic that solid state can't quite match. The tube maintains a high level of detail while taming harsh digital files. We strive for a musical presentation rather than questing for that Nth level of "in your face" extension. The quest for music reproduction shouldn't be a contest to attain the highest number, rather one to seek an emotional experience while maintaining the musical intent of the artist. Our goal is for you to enjoy the music, not think about the box.
Inputs The Nova has 8 total inputs: 5 digital, 3 analog. A USB input for your computer in addition to 2 coax and 2 optical inputs for other digital sources like Squeezebox®, Apple TV®, AirportExpress®, Sonos®, and XM or Sirius® tuners. The Nova also has 3 analog inputs for docking stations, CD players, tape decks or phono preamps.
Outputs If you want to add a subwoofer or outboard amplifier, the Nova features a “Class A” <30 ohm variable preamp-output that will impedance match to almost any amplifier while pushing up to 100 ft of cable.
Noise Computers and other digital devices are notorious for CPU and switching power supply noise. Each digital input is transformer-coupled to prevent contamination of the digital signal.
So do we feel we have a fantastic preamplifier in the Nova? Oh yes!
Home Theater Bypass and Digital Filter
The Nova's third analog input doubles as a “Home Theater Bypass” so you can have the best of home theater and two-channel in the same system. Simply take the left and right “pre out” from your receiver or processor and connect to the “Home Theater” bypass on the Nova. A selector switch on the back panel converts from Aux to HT bypass. In this application your receiver transparently uses the L&R amplifier section of the Nova. This leaves the receiver responsible only for pushing the center and rear speakers, making the receiver much more efficient and less taxed. And when you listen to a two-channel source plugged directly into the Nova, there’s a straight line from the source to the Nova to the speakers . . . no processing, no running the signal through a forest of circuitry. This leaves little between the music and your ears. If you’re a two-channel fan, it’s the way to do theater right!
Digital Filter The Nova's switchable digital filter lets you tailor your system and your recordings to your taste. Although the Sharp setting measures better, many listeners prefer the sound of the Slow setting, and we recommend it. Let your ears be the judge.
For the headphone user, the Nova has a class A tube headphone section that rivals some of the best headphone amps available. When your headphones are plugged in, the speakers are automatically muted - so you can rock on when quiet is a necessity. Headphones have never sounded better than through the Nova.

The Nova has enough connectivity to handle a wide variety of digital and analog sources. It will work great as a traditional analog integrated amplifier, but with such a glorious DAC section, it would be a crime not to take advantage of its processing power, with which any computer-based music server can be turned into a hi-fi source. You can even use a Sony PlayStation 3’s optical output and transform the PS3’s sound into real hi-fi. The possibilities are almost endless.
The Peachtree Audio Nova is a ton of fun and has a bright future as everyman's high end integrated amplifier, DAC, or preamp. Hence the title of this review, Champagne Supernova. Champagne always involves fun and Supernovae are incredibly luminous. Champagne Supernova is also a reference to the Oasis song of the same name. A seven minute anthem that hit number one on the modern rock charts in the U.S. and has been played at every Oasis concert since it was written. The song has been spinning my NAS hard drives quite a bit lately. Sure the Peachtree integrated amp is called the Nova, but the musicality, enjoyment, and versatility of this piece may warrant the name Supernova.
Consider this: the Nova can go toe-to-toe with the Benchmark on sonic
grounds, offers more flexible inputs (3 analog and 5 digital for the
Nova vs. the 1 analog and 5 digital for the Benchmark), comes with a
remote control, and serves not only as a
DAC/preamp/headphone amp but also as a full-on hybrid integrated
amplifier—all for about $395 less than the price of the Benchmark.

The Nova is no mere integrated. It includes a converter which most competitors don't. To test the secret weapon, I switched to one of its digital inputs and let the Logitech Transporter supply the ones and zeros. While nothing in the previous paragraph turned sudden lie, sonic changes immediately manifested as deeper colors. Bass and treble gained presence, staging moved forward and also expanded laterally. Now there was more life in the music.
