NuPrime Evolution STA
"A typical feedback error correction design inverts the output signal for summation with the original input signal to derive the negative error signal, which adds to the next cycle of the input signal to form a more accurate output signal. Nuprime's ODC Class-D design derives the error signal from MOSFET devices and the output filter circuit directly, significantly reducing the negative feedback signal, which resulted in a substantial reduction in distortion THD+N of 0.002% @1kHz(5W), and less than 0.005% THD+N at 1KHZ (2W-100W). This breakthrough improvement in Class-D design resulted in a natural and pure sound characteristic."
The STA features a dual-mono configuration with a Hybrid Class-D technology that takes advantage of both Class-A and Class-D amplification. A refined 550W high-power ultra-thin toroidal transformer delivers cleaner and more stable power with low noise. Instead of using cables, STA has copper signal paths for connection to maximize power delivery internally.
The entire power path offers high current via low resistance terminals from Eichmann .
Evolution STA's sound characteristics can be described:
- Wide and deep sound image without loss of clarity at lower frequencies.
- With large-scale orchestral recordings, you'll be able to clearly see the deepest notes of percussion and wind instruments, even the subtle pedal sounds! These details are presented truthfully without artificial embellishments
- Fast dynamics with large scope
- Natural and clean thanks to ultra-low distortion
- Clean and black background that gives greater details and more nuances
