Stunning Results

We take great pride in what we have accomplished with the new nova150. It accommodates virtually every type of music source people use today, from spinning vinyl at home to streaming audio from the cloud. We've ushered in an impressive new suite of technological advancements - from the DAC through the power amplifier and at every step in between. This new nova is designed around tried and true audio engineering philosophies to ensure exceptional sound quality and superb measured performance across the board. The new novas - there are more to come! - are truly the most beautiful and exceptional sounding products we have ever made and are every bit deserving of the designation nova 2.0. We hope you choose to make one a part of your musical life. We are confident that if you do, you will love it!

  • Reference DAC

    ESS 9018S

    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.

    World-Class Preamplifier

    tube buffer

    Where's the TUBE? The tube is GONE?!?

    Yes, it is. Because the new nova preamp is just so 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.

    The new amplifier modules in the current generation of nova are inherently warmer sounding than previously, while still retaining the accuracy digital amps have always provided. Combined with a cleaner analog section and no noise created by an internal tube circuit and we're now able to get even closer to the sound of the original musical performance. The newly-designed preamp section in the nova150 has a S/N ratio of 111dB and is a major contributor in getting us closer to that original sound.

    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 DyNEC (Dynamic Noise Elimination Circuit) for iPhone/iPad

    iPhone

    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!

    iPad

    By its very nature, any computer generates "noise". A computer's power supply is one source of this noise. Years ago we attacked this issue of computer-generated noise by isolating the USB inputs of our amplifiers. Having successfully conquered "conventional" computer noise, we want to be sure you enjoy the same noise-free performance from your iPhone and iPad.*

    *Smart phones, notepads and tablets are, of course, small but powerful computers. Power supplies and high-resolution screen refresh rates are possible sources of noise contamination.

    With this goal in mind, Peachtree engineers have developed DyNEC: the world's first and only system to address and eliminate all audible power supply and screen noise. DyNEC assures your music files are streamed to the nova free of any added noise - so your favorite music sounds its very, very best!

    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!
