Krell Illusion II Stereo Preamplifier; Black The Music Room

Brent Butterworth sits down with the Illusion II digital stereo preamplifier from Krell, which includes five digital inputs and a 24-bit/192-kilohertz ESS Sabre DAC. It also has four stereo analog.. Featuring 700 kHz bandwidth in a zero feedback, balanced, Krell Current Mode design, the Illusion II shares the same design philosophy as its bigger brother, the flagship Illusion preamplifier. Negative feedback is not used anywhere in the preamp, nor is it necessary. Open-loop distortion is typically less than 0.003%.

The Krell Illusion Preamplifier represents the pinnacle of Krell's engineering prowess, combining advanced circuitry and high-quality components to deliver unmatched audio performance. Designed for discerning audiophiles, the Illusion preamplifier separates the power supply from the audio circuitry to minimize noise and maximize sound purity.. The Illusion preamplifier extends the Krell tradition of separating the power supply from the audio circuitry in our flagship preamplifiers. Sharing the new Class A iBias power amplifier aesthetic and featuring Krell CAST technology, the Illusion preamplifier is the ideal match for the new Solo 375 and Solo 575 power amplifiers..
