With the Evolution One, NuPrime has made several design advancements:
- A new input stage with a 1MΩ input impedance. The high input impedance allows the pre-amplifier to see a much easier load and hence introduces less harmonic distortion and phase delay to the system.
- Latest NuPrime 700KHz high-speed switching Class-D module allows greater resolution to be achieved.
- High-speed computing simulations were performed for the Evolution One design, in order to achieve the highest input impedance and the lowest phase delay.
- The power supply has been enhanced to deliver cleaner and more stable power with lower noise floor.
- High Quality copper strips instead of usual cables are used to connect the power supply to the amplifier’s circuitry, maximizing power delivery.
The NuPrime Sound
The Evolution One outperforms its predecessor in every aspect which NuPrime amplifiers are known for by having:
- Wider and deeper soundstage
- Faster dynamics with greater range
- Lower distortion and noise
- Cleaner background that provides greater detail and nuances
Our new generation of amplifiers have moved even further away from the cold, hard, flat and harsh sound typically associated with Class-D amplification. The Evolution One has Class-A like warmth and naturalness that no other competing Class-D amplifier can recreate.
In addition, the Evolution One is able to create an enveloping ambience that reaches out and invites the listener to the music. All these pushes the performance of the Evolution One to yet a higher level!
Our Proud Achievements
Very few manufacturers could design a 1MΩ input impedance without adversely affecting noise and stability, and those amplifiers are priced many times higher. The Evolution One is the first Class D amplifier to successfully implement a 1MΩ input impedance and the only one in its price range of any type of amplifiers.
Many good audio equipment though can present a deep soundstage, clarity gets lost at the depths as they become susceptible to interference. The Evolution One has a very deep soundstage, and can present a clear image even at the greatest depth. With large scale orchestral recordings, you will be able to have a clear image of the last rows of percussion and wind, even the subtle pedal sounds! Such details are presented in a truthful manner without artificial enhancements.
Class-D amplifiers from most manufacturers sound cold and clinical, excelling primarily in their power efficiency and high power output. With the Evolution One, NuPrime has achieved a Class-A like sound with our hybrid Class-D technology that retains the merits of both Class-A and Class-D amplification. Through our efforts in research and development, the Evolution One could easily compete with the best Class-A amplifiers in the market, without the bulk and heat generation.
The Evolution One presents the most untainted and transparent sound with a completely flawless background. Recordings comes through as they are meant to be, as if you are right there at the performance. Be surprised by the revelation the Evolution One will bring to your music!

NuPrime Evolution One 單聲道後級擴大機
– 林治宇, u-audio.com.tw
“…以阿格麗希演奏蕭士塔高維奇的第一號鋼琴協奏曲為例，第一樂章前段弱音的鋪陳就顯得頗具張力，輕重對比鮮明，鋼琴觸鍵的重量感明確，尤其是背景幫襯的弦群綿密如織，起伏連貫，快慢有致，讓人感覺音樂處處暗藏機鋒。隨後的強奏EVO One表現得輕鬆寫意，迅速帶起熱烈的激昂感，音場結構井然有序，彷彿再複雜的場面都在掌握之中。我還聽到不僅鋼琴觸鍵的重量感優異，顆粒飽滿，而且小號兼具密度與金屬光澤，穿透力十足。更棒的是，音場下盤既穩且沉，低頻層次豐富之外，更因為主奏鋼琴的音像凝聚，顆粒形體清晰，伴奏聲部在後方層次分明，更凸顯主奏與樂團主從地位的分別。就是這樣的條理分明，顯示EVO One處理複雜音樂更駕輕就熟，性能更為卓越…”
NuPrime Evolution One Review in AudioCircle
– gammajo, audiocircle.com
“…First noticed was the freedom from an ever so slight, unnoticeable-till-its-gone digital haze. Wow! Minor and subtle, yet highly important. Next was that the soundstage was much improved in terms of depth, separation of instruments, and air and bloom. Then I was entranced at how much more natural and beautiful high bells sounded – more rounded with more realist timbre, attack, and decay. All voices, especially female vocalists were more natural and captivating. Yet when music was supposed to be edgy it was, they could rock out with the best. When the music is relaxed and sweet, these amps allow you to be emotionally moved by liquidity and languidness ( I think because they sound less digital). This involvement could still be enjoyed at lower volumes than with other amps. They are excellent at naturally presenting the slightest micro-detail with no excessive spotlighting. Solo and massed strings were more realistically presented both in the string sound itself and the body of the instrument.
Where I found the Evos clearly better than any other amp that I have heard in any typology is with highly complex classical music such as symphonies but also complex rock and new age. Everything is more naturally delineated and more realistic sounding even when 100 diverse instruments are playing at once. In fact, I have been listening to much more symphonic music with these amps, where before there was something unsatisfying about the reproduction of such massive and detailed soundscapes. Solo instruments in these works stand out more clearly in character from the mélange of sound around them and dynamic swings are surprisingly instantaneous….
…I like the sound of Pass Labs, Constellation, and VAC amps, yet not even considering the price, size, and heat difference, feel like I like the Evos better. They hit the sweet spot between fluidity and control. There is ample mico-detail for this detail freak and yet they present the music as a whole cloth to be enjoyed as a living presence.”
NuPrime Evolution One Monoblock Amplifier
– Neil Gader, theabsolutesound.com
“..Class D generally has never gotten the love it deserves. However, the performance of the Evolution One largely undercuts those preconceptions and redefines what it means to be a top-tier monoblock amp in 2019.
..the Evolution One allowed music to unspool effortlessly without electronic affectation.
Transients were naturalistic (more on this later), and there’s was no indication of etch or grain in the upper octaves…
Key to the Evolution One’s performance was the finesse it exemplified reproducing inner detail. That could be Brubeck’s touch on the piano keys, Ringo’s brushes playing off the skin of a snare, even the tick of a flat-pick on Chris Thile’s bluegrass mandolin—pretty much any pattern of single notes played by an individual or a section of players. A great amplifier needs more than just a low noise floor, it also has to have the responsiveness and speed to reproduce the ever-changing gradations of energy emanating from each instrument or combo. These are not elements that we necessarily isolate in our minds, but the transient and microdynamic surprises are what spark our ears to attention. Such attributes define the “live” experience for this listener.
…
Images were so unwaveringly stable that they could have been applied with crazy glue…
Today I see no sonically valid reasons to raise an eyebrow at Class D amplification. In short, it’s high time that audiophiles park their biases at the door. In its Evolution One, NuPrime, in grand fashion and with musicality to burn, has laid to rest the argument that Class D is somehow intrinsically inferior to traditional Class A/AB. Every amp, regardless of letters of the alphabet, needs to be judged on its musical merits, not its topol- ogy. That’s always been what the high end is about. My recommendation couldn’t be more enthusiastic. Evolution really does improve the breed.”
NuPrime Evolution One Power Amplifier
– CHRISTIAAN PUNTER, hifi-advice.com
“…Naturally, there were many more implementations using ICE and Pascal modules that I have not used in a controlled environment but judging from what I heard at shows, it seemed that class D would never be it for me. Then I heard the NuPrime ST-10 using proprietary class-D circuitry and it changed everything. The ST-10 does not sound like a typical class-D amp at all. It has bass control and heft easily as good as the best Pascal amps I heard, a natural timbre even better than that of many class AB amps and while its transparency and resolution could be better and its treble lacks fluidity and air, the amp has such magnificent PRaT and makes for such a lively and engaging performance that you quickly forget about that. …
…The Evolution Ones were used in several scenarios, both using my own systems as well as in two friends’ systems and a pattern soon emerged. Wherever they were used, they were like chameleons, always refrained from editorializing the sound. These amplifiers really are as neutral as they come…
The Evolution Ones sound crisp and clear yet richly textured and timbrally natural, with excellent focus and a reach-out-and-grasp solidity to objects within the soundstage along with a level of lifelike purity and directness that is quite rare. The amps do not rose-tint of otherwise beautify the sound in any way which does make their performance highly dependent on the recording quality. These are reference amplifiers for those who wish to hear precisely what is in their recordings.”
Amp & Preamp (3)
In some applications, the speaker outputs from the power amplifier are used as source signals for devices such as REL sub woofer. For such application, usually the receiving devices should have DC offset blocking capability because some amplifier by design has floating ground (DC offset) on the speaker outputs.
The following models have no DC offset on the amplifier speaker outputs and the negative terminal is also the ground:
NuPrime STA-9, MCH-K38, IDA-6, IDA-16, STA-9X, AMG STA
The following models’ speaker outputs can not be connected directly to sub woofer input:
NuPrime Reference 20, ST-10, IDA-8, ST-10M, Evolution One, Evolution Two, Evolution STA, AMG One, MCX-1,2,3,4
REL has provided instructions for connecting Class-D amp with floating speaker outputs to their sub woofers, please contact REL. All currently shipping REL sub woofers can be connected directly to any Nuprime amps.
IDA-8 is an extremely popular and award winning integrated amp. New users are welcome to read this long topic on audiocircle.com: http://www.audiocircle.com/index.php?topic=134697.0
When a device has a 12V trigger input, it is designed to be turned on when a 12V is detected. You can use any standard male to male 3.5mm (3-pin type) cable.
https://components101.com/connectors/35mm-audio-jack
The Tip section is +12V, the bottom Sleeve section is GND, and the middle Ring section is not used. Nuprime’s trigger design uses 3.5mm stereo cable pin 1 and pin 3. A mono trigger cable shorts pin 2 and pin 3, it can be used to connect the Nuprime device to another device’s trigger that only uses a mono cable.
