CLASS-D HAS NEVER BEEN SO GOOD. COME TO THINK OF IT, NEITHER HAS CLASS-A...
Kaluga is based on world's most sought after class-D technology: Ncore®. Unprecedented low distortion, noise and output impedance combine into what scores of enthusiastic users unanimously describe as “no sonic signature at all”. Just music, glorious music. For instance, the two supposedly unassailable strongholds of class-A amplifiers are linearity and output impedance, at high frequencies. Plotted on next page are the output impedance as a function of frequency and the output spectrum in a high power (400W), high frequency IMD test. In both cases Kaluga outperforms any power amplifier, regardless of technology, operating class or asking price, of which such test results are available.
