Kaluga Mono Power Amplifier
Kaluga, based on the world-renowned Ncore class-D technology, offers unparalleled low distortion, noise, and output impedance, delivering 'no sonic signature at all.' It outperforms all power amplifiers in output impedance and high-frequency linearity. The Mola Mola-specific design features minimal audio circuitry, direct soldering for low impedance, and discrete buffers in the input stage. The output filter uses monolithic capacitors for a neutral sound. Kaluga combines power efficiency with superior audio performance, marking the end of compromising one for the other. Enthusiastic users unanimously praise its pure, glorious music output.

KALUGA MONOBLOCK
The amplifier board is a Mola Mola specific design. The audio circuitry is trimmed to the bare bones and board-to-board connectors are eliminated in favour of soldering star-quad cables directly into the circuit board for the cleanest, lowest impedance connection possible. The input stage is implemented on a separate circuit board that uses the same discrete buffers as those found in the Makua. The output filter sports monolithic capacitors whose dielectric stability is reflected in an impressively neutral and poised rendition. The days of compromising power efficiency for audio performance are finally over: the Kaluga delivers definitive audio performance with power efficiency thrown in as a bonus.
The two supposedly unassailable strongholds of class-A amplifiers are linearity and output impedance, at high frequencies. Plotted below 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.
