Krell

A high power iBias technology stereo power amplifier DUO 300 XD offers Class A sound quality while maintaining efficiency. Advanced cooling system guarantees flexibility of use.

The KRELL KSA-i400 is capable of developing 400 watts when operating on a load with a nominal resistance of 8 ohms. For a 4 ohm load, the maximum power is doubled, and for a 2 ohm load, the amplifier is ready to reach 1.6 kW. When the load resistance drops to 1 ohm, the KRELL KSA-i400 is capable of delivering a peak current of up to 62 amperes. The amplifier implements the most advanced patented technologies of Krell iBias, XD and Sum-Max.

The amplifier uses XD technology (lowering the output impedance for better control of speakers and more accurate music playback) and iBias technology (which allows you to combine Class A sound qualities with the dynamics of classic Krell amplifiers, as well as the efficiency and low power consumption of Class G and H amplifiers).

The Krell DUO 175 XD weighs 31.8 kg, develops 2 x 175 watts at 8 ohms of load, has a signal-to-noise ratio of 115 dB and reaches a peak current of 13 A (the dumping factor of the amplifier is 210 units). The XD (Extended Dynamics, Xtended Dimensionality, Extended Detail) scheme provides excellent resolution over the entire spectrum of audible frequencies and brilliant dynamic characteristics.

The five-channel KRELL Chorus 5200 amplifier, using the new Krell iBias technology, ensures the operation of output amplification stages in pure class A at any output power, but with efficiency close to classes G and H. Class A differs from AB in the absence of switching distortion and, as a result, higher-quality sound.
