NuPrime Evolution STA Stereo Power Amplifier
The NuPrime Evolution STA offers a breakthrough in distortion reduction. Coined the Only Distortion Cancellation (ODC) design, NuPrime has continued advancing the state-of-the-art Class-D for the past decade. Reaching a similar performance level as the Evolution One monoblock, the Evolution STA offers the best of the ST-10 and the AMG STA while improving the performance to a higher level.
Features
- NuPrime breakthrough Only Distortion Cancellation (ODC) Class D design.
- Preamp stage and Class D oscillation circuit utilizing high-end NJR MUSES8820 op-amp.
- 650KHz high-speed switching frequency allows greater resolution to be achieved.
- The 550W high-power ultra-thin toroidal transformer power supply has been enhanced to deliver cleaner and more stable power with a lower noise floor. The entire power path fully adopts 40A ultra-high current and low resistance terminals. Improve current dynamic capability. Total of 52,000uF power supply filter capacitors.
- High-quality copper PCB trace instead of usual cables are used to connect the power supply to the amplifier’s circuitry, maximizing power delivery.
- Hybrid Class-D technology that retains the merits of both Class-A and Class-D amplification.
- A stereo amplifier with dual mono implementation.
