Peachtree nova150 Integrated Amplifier with DAC
The Integrated Amplifier… Reimagined
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 5.6MHz 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.
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!
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. Peachtree wants to make sure you achieve MAXIMUM performance from these high-tech marvels!
Once all sources of noise are eliminated, music files are "handed off" to our internal ESS SABRE32 Reference DAC - further improving performance via asynchronous connection, and eliminating any timing errors caused by jitter.
With DyNEC and an asynchronous connection, Peachtree's dedicated iOS input lets you hear your music with all the clarity, dynamics and emotion the artist intended. So can the iPhone and iPad - perhaps the most convenient music playback devices ever - be taken seriously as high-end audio components? Connected to Peachtree's iOS input, our answer is a resounding YES!
Power Amp Mode
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.
