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.
