The NuPrime amp circuit improves on traditional Class-D design by using a self-oscillating circuit to generate
pulse-width modulation. The amplifier switches at a frequency of 550kHz, well beyond the compact disc’s
44.1kHz sampling rate. Most class-D amps switch at 300kHz or lower. Completing the ensemble is
NuPrime's new linear power supply with its high-efficiency toroidal transformer for reduced high-frequency
noise and strengthened low-frequency performance. The damping effect of the NuPrime isolation feet
(patent pending) absorbs and cancels vibrations that degrade audio performance. The overall result is
unprecedented transient speed and an almost shocking level of dynamic impact.
The STA-9's frequency response to 50 kHz elevates vocals into emotional experiences; similarly,
instrumental upper registers mimic a live performance’s shimmering heights.
Features
•
Single End Class A + D amplifier design
•
Bridgeable allowing switch between stereo or mono mode.
•
Enhanced even-order harmonic (H2) circuitry resembling the most attractive features of tubed-amp
sound without its drawbacks and limitations.
•
Highly reliable under no-load condition and enhanced short circuit protection.
•
High output current drive capability for low impedance speakers.
•
550 KHz switching frequency for accurate reproduction of musical signal.
•
New linear power supply with a high-efficiency toroidal transformer. Reduced high-frequency noise
and strengthened low-frequency performance.
•
Signal path avoids cross-linking capacitors, thus achieving a frequency response at DC level for pure
musical enjoyment.
