Evolution One – JAW DROPPIN` GOOD! – FULL REVIEW by Stjernholm
– John Ransley, Totally Wired Limited
“…The Evolution Ones are giving us the best of sound quality attributed to Class A or tubes – the fluidity, ease and open nature, yet eliminating the downsides of heat, power consumption, noise and compromised long term reliability. They bring the best of solid state – high power, exceptional bass control and an astonishing frequency range…”

“…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…”

“…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.”

“..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.”

“…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.”
