NuPrime Evolution One, HighEnd Mono-Endstufe

NuPrime Evolution One

Die Endstufe NuPrime Evolution One ist ein „technischer Meilenstein“. Die leistungsfähige und kompakte Endstufe leistet 420 Watt sinus an 4 Ohm. Sie kann sowohl symmetrisch per XLR als auch unsymmetrisch via Cinch betrieben werden.

Die extrem hochohmige Eingangsstufe mit 1 Megaohm Eingangsimpedanz und eine 700 kHz „schnelle“ Ausgangsstufe fördert einen transparenten und fein aufgelösten Klang zu Tage.

NuPrime Evolution One  came from the evolution of esteemed NuForces award-winning Reference amps, after NuPrime has acquired the NuForce high end product line. While the Reference 20 retains all of the Reference 18s superior sonic attributes, the amps higher 420W @ 4 Ohm output power brings one closer yet to the goal of supreme performance. The Ref 20s low-ESR Cross Matrix Array (CMA) capacitor assembly features high-performance capacitors in a proprietary, non-resonant alignment. Unifying such refined technology with superior power yields truly unsurpassed speed, transparency and resolution, along with genuinely authoritative dynamics. The net response is a natural, non-fatiguing rendition of music that simply flows from a palpably real soundstage.

The Evolution One is the embodiment of all the latest and best technology NuPrime has developed. From the power supply, amplifier circuitry, to a new highly advanced input stage; the Evolution One has been carefully crafted to achieve a performance that surpasses the Reference range performance in all areas.

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.
