Producing 120Wpc and weighing just under 10.5 pounds, the STA-9 uses a Class A input circuit along with a Class D output circuit. NuPrime’s website says it “is designed with enhanced even-order harmonic circuitry that mimics the most attractive features of tube-amp sound without incurring tubes’ drawbacks and limitations.” It’s easily bridgeable into 290Wpc monoblocks, and its 47k-ohm input impedance should work with virtually any preamplifier. In monoblock mode, the STA-9 produced powerful bass, even with small KEF speakers.
