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.

The Evolution One contains some new developments such as a new input stage with a 1MΩ input impedance. According to the manufacturer, the high input impedance allows the pre-amplifier to see a much easier load and hence introduce less harmonic distortion and phase delay to the system. The latest NuPrime 700KHz high-speed switching Class-D modules are used which according to the manufacturer allow a greater resolution to be achieved. Contrary to the ST-10’s linear power supply, the Evolution Ones have a Switched Mode power supply on board and with a power rating of 240W into 8 ohms and 330W into 4 ohms

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
