Krell

New powerful high-voltage high-frequency transistors are used at the output of the Krell Solo 375 monoblocks. Multi-storey current mirrors are used to increase linearity in cascades with direct connection. Speaking about the features of the Solo 375, it is impossible not to mention the cooling using low-noise fans that maintain a constant temperature of critical parts of the amplifier, as well as the ability to control operation and monitor important parameters over the network.

The bandwidth of the Krell KMA-i800 extends up to 147 kHz with an error of 3 dB, and the basic performance characteristics are provided by the company according to a much more stringent standard. The model has a dumping factor of 800 units and uses a monstrous 5,400 VA power transformer and a 188,000 UF capacitor bank. The output stage is unique – a pair of out-of-phase amplifiers is used, which provides twice as much distortion attenuation.
