Peachtree Audio Nova150 Integrated Amplifier with on-board DAC - GLOSS EBONY MOCHA

Pin It
The Integrated Amplifier… Reimagined

We now introduce nova 2.0 . . . a completely new generation of Peachtree integrated amplifiers that reimagines the original concept and takes it to an even higher level. Nova 2.0 is the culmination of everything we've learned as a leader in computer audio, plus a few new things we hadn't gotten to - until now!

Reference DAC

The nova150 utilizes the highly regarded ES9018K2M SABRE32 Reference DAC. The 9018 DAC is capable of accepting an extremely wide range of inputs all the way up to 32-Bit/384kHz PCM and 5.2MHz DSD (double-DSD). The DAC exhibits exemplary dynamic range, jitter elimination and low noise characteristics to satisfy even the most demanding listeners.

A New Generation of Power Amplification

The nova150 incorporates the latest generation of ICEPower amplification - with an impressive 150 watts per channel. The amplifier utilizes ICEpower’s innovative and patented Hybrid Controlled Oscillation Modulator (HCOM) feedback and control techniques to ensure high output, wide bandwidth, low noise, robust stability and a simplified overall design. HCOM incorporates separate feedback loops after the power stage and after the output filter. This lets the system address specific issues related to the power stage and output filter independently, resulting in lower distortion, less noise on the output, a less load-dependent frequency response, and a very low output impedance compared to other class D amps. This new amplifier technology is extremely powerful, dynamic, quiet and most importantly... musical. Relatively small size and superior efficiency allows a nova chassis that is even smaller than its predecessors, without the large, heavy and expensive heat sinking common in class A/B amplifiers. The amplifier in the nova150 is capable of driving an extremely wide range of speakers with impedances as low as 2.5Ω and as high as 16Ω. Combine that with a power output of 150 watts per channel and you can be sure this new nova will easily drive your favorite loudspeaker.

World-Class Preamplifier

Where is the tube? The tube is gone?!?Yes, it is. Because the new nova preamp is just too good! Previous generation Peachtree preamps had a signal to noise ratio in the range of 95 to 100dB, similar to competing preamps. When our signature tube buffer was engaged to smooth out a rough recording the S/N dropped to 88-90dB, an acceptable compromise for the sonic benefit.

By contrast, the newly-designed preamp section in the nova150 has a S/N ratio of 111dB. This is unheard of in its price range! Taking that 111dB S/N down to 88dB with a tube follower would sound like you'd thrown a blanket over your system.

So has Peachtree given up on tubes? Not at all. We're planning a proper stereo tube buffer, complete with separate power supply, for the future. This will connect into the LOOP input/output of the nova amplifiers.

Quiet as a Mouse

The nova150 utilizes an extensive power supply and grounding design to ensure the noise floor is pushed as far down as possible to allow the music to shine through. Our engineers spent hours upon hours determining the optimal power supply filtering and grounding scheme to prevent any unwanted noise from finding its way into the signal path. As a result, the nova150 achieves a remarkable dynamic range and signal-to-noise ratio. Turn up the nova150 to full volume without music playing, put your ear to the speaker and enjoy the lack of noise!

iOS Input - Introducing Dy-NEC (Dynamic-Noise Elimination Circuit) for iPhone/iPad

The nova150 includes a dedicated asynchronous USB connection on the rear panel that provides a direct digital wired connection for Apple Lightning-equipped devices. Simply use the cable that came with your iPhone or iPad and enjoy your music transformed by the ESS SABRE32 Reference DAC and the superior sonic performance of the nova!

We know that streaming music files from the Lightning connection on the iPhone or iPad is VERY convenient. But from a purely objective perspective, these devices are sources of noise! And from an audiophile perspective, this noise must be eliminated before the iPhone or iPad can be taken seriously as a high-end audio component.

Enter Peachtree. The only company to take this task on so far is Peachtree Audio! All other designs are plagued with this noise on their iOS input.

We first traced noise problems back to power supply fluctuations - and successfully addressed these with isolation. But a much more serious offender - by far - was the retina display screen on the iPhone or iPad! These beautiful displays have refresh rates in the millions of times per second range, causing audible noise through your speakers. You can easily hear this noise by simply running your finger across the screen when connected to a similar input on a competing product. So the retina displays posed a tricky problem, but knowing how important the iPhone and iPad are as music sources for so many listeners, Peachtree thought it important to maximize the effort and do something that’s never been done before.

With this goal in mind, Peachtree engineers have developed Dy-NEC: the world's first and only system to address and eliminate all audible power supply and screen noise from these devices - giving you the best, most silent platform so your music files can sound their very best.

Once noise was eliminated, a music file could then be "handed off" to our internal ESS SABRE32 Reference DAC - further improving performance with an asynchronous connection, eliminating any timing errors caused by jitter.

With Dy-NEC and an asynchronous connection combined, the Peachtree iOS input easily outperforms any input of its kind on the market, regardless of price. And . . . the new metal-faced Peachtree remote controls basic iOS functions like FF/RR and pause, so you can just sit back and enjoy!

Dy-NEC is a Peachtree exclusive.

What’s Old is New Again

We are pleased to say that the nova150 includes a moving magnet (MM) phono input for direct connection of a turntable. Yes, that's right - a bunch of computer audio advocates made a phono preamp! And not just any phono input... a custom designed circuit that accommodates a wide range of MM cartridge outputs. With the nova150 you no longer need an external phono preamp unless you are using a lower output moving coil cartridge. In that case, the internal phono preamp in the nova150 can be bypassed, allowing the phono input to accept line-level signals from a dedicated phono preamp or any other line-level device. Win-win!

Home Theater Bypass (HTB) is Back!

This is one of our most requested features and it is included in the nova150! HTB allows for easy integration with a multi-channel preamp/processor or audio/video receiver (AVR) so that the power amplifier in the nova150 drives the front left and right speakers for stereo and multi-channel listening. The nova150 amplifier section is likely more powerful and better sounding than any AVR available today - and relieving the AVR from driving the front left and right speakers makes it MUCH easier for the AVR to drive the center and surround speakers. When listening to stereo music the nova150 becomes your control center, and you can enjoy the full benefit of its reference DAC and ultra-low-noise circuitry. If the HTB input isn't needed it can be configured as a standard analog line-level input.

Getting LOOP-y

The nova150 includes an extremely useful Loop (output/input) feature, allowing you to add an external tube buffer, equalizer or other processor into the signal path as desired. The LOOP button on the remote control engages and disengages the loop audio path utilizing high-performance relays. Do you want to experiment with room correction? No problem. Wire your room EQ component into the nova150 and use the LOOP button on the remote control to easily A-B between correction in/correction out.

The nova150 provides a Volume Control Bypass feature on its digital inputs which puts the nova150 into a "power amp" mode. This is particularly useful if you have a connected source with its own volume control. Have a favorite device or app with a volume slider built right into the interface? Simply bypass the nova150 volume control for that input and use the app slider instead. VERY convenient!

Optical, Coax and USB Inputs

The nova150 offers a standard suite of digital audio inputs, including asynchronous USB for a computer. In addition, there is one coaxial S/PDIF input and two optical inputs that accommodate signals up to 24-Bit/192kHz, assuming the connected device can output those signals. If it can't, no worries; use your computer instead to output your high-res files to the nova150's asynchronous USB input.

Discrete Headphone Amp

Headphone fans will love the newly designed discrete low impedance headphone amplifier in the nova150. It can easily drive any headphones on the market, and drive them well. The signal-to-noise ratio of the circuitry will impress even the most dyed-in-the-wool headphone enthusiast! When you plug headphones in, the speakers and preamp outputs are automatically muted and the volume knob becomes a dedicated headphone volume controller. Unplug the headphones, and the system reverts back to being an integrated amplifier.

Optional Wi-Fi Module

The nova 2.0 platform was designed to accommodate an internal Wi-Fi module, which is currently under development. We have even reserved an input button on the front panel for it! This will allow you to stream audio directly into the nova150 without the need for connecting any wires. Until then, you can easily connect to the world of streaming audio via a Wi-Fi enabled computer or iDevice, Apple TV (3rd generation), SONOS Connect or Google's Chromecast Audio (to name just a few).

World-Class Engineering

When we set out to reinvent nova, we called on a team of world-class engineers to design a platform that would achieve our simple but lofty objectives: superior performance, more inputs, greater flexibility, wireless capability, smaller size - all this, plus built in North America within the price range of our previous integrated amplifiers. We came together and created nova 2.0: the best sounding, most accommodating and most reliable integrated amplifier platform we have ever built. The nova150 has arrived and the results speak for themselves.

Made in North America

The nova150 is designed and built in North America. The circuit boards are built, the amplifiers assembled and fully tested, then inspected at an ISO 9001:2008, 13485:2003 (Medical Devices) and MFi Certified Facility in Canada. Amplifiers are then shipped to our facility in Bellevue, WA where the wooden case is installed and the final product inspected again! Building this product in North America was a coordinated team effort and a significant milestone in Peachtree's history . We are extremely proud that the nova150 is designed and built in North America!
