Class A+D Stereo Amplifier Brigeable into a 160 watt Mono Amplifier

With 2 X 90W Class A+D stereo amp, bridgeable into a 160W mono amp, STA-6 is designed with enhanced even-order harmonic circuitry that produces sonic characteristic similar to NuPrime STA-9, but leaning toward neutral with a slight hint of warmth. The STA-6's spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to believed.

What is a high-end DAC?


NuPrime has designed a $99 Encore mDSD portable DAC and a $179 NuPrime uDSD DAC that are both capable of decoding 32-bit/384kHz and DSD256, therefore the DAC chip itself has advanced to the point of becoming a commodity and is no longer the biggest differentiating factor. Newer generation of DAC chips only provide diminishing return. Different brands of DAC chip have their own sonic characteristic but a skilled engineer could tuned the sound of a DAC with transistors in the preamp stage.
Power supply and preamp are now becoming the dominant factors in the DAC's performance. In this post, we will discuss about the preamp and volume control. Entry level DAC such as the $99 Encore mDSD can sound like a reference class DAC if it is used with a high-end in-ear earphones and a computer USB audio. But for a high-end DAC to work with a variety of analog and digital inputs, the volume control and preamp has to be exceptional.

What is high-end audio?


Robert Harley, Editor-In-Chief of The Absolute Sound, states that “High-End Audio is the quest to re-create in the listener’s home the musical message of the composer or performer with the maximum realism, emotion, and intensity.” Historically, skilled audio professionals have created high-end audio components by carefully crafting circuits and taking great care in parts selection. They achieve great sound through elaborate, time-consuming processes, resulting in expensive and often opulent products.

Hybrid Class-D Amplifier Design With Different Sonic Characteristics

At NuPrime, we’ve made a huge leap forward in building world-class amps with different characteristics. Going from achieving one near-perfect design to another, but with different sonic characteristics is a daunting challenge. Very often, when one enhances one sonic aspect he loses another. If we’re aiming at a product that sounds like a tube amp, we don't want to sacrifice dynamics and speed, and therein lies a stellar achievement. To help readers understand how we get here, we will like to take you back in history where it all begins.

NuPrime's patent-pending anti-vibration feet typify NuPrime's innovative excellence irrespective of price. This innovative feature is included in most of the products.

The damping effect of NuPrime’s isolation feet absorbs and cancels vibrations that degrade audio performance. This manner of shielding from interference results in a pure and natural sound.
