Krell Readies Pair of Stereo Preamps

By Joseph Palenchar March 6,2014




Krell Industries plans shipments next week of a pair of high-end stereo preamplifiers designed to match the performance levels of select high-power Class A amplifiers shipped last week with iBias technology.

The new preamps are the $15,000 Illusion with separate power supply and the $7,000 Illusion II with digital inputs. The preamps match the cosmetics of the company’s seven iBias amps, which range in price up to around $10,000. iBias technology improves Class A efficiency and reduces Class A amplifier size to suit changing consumer tastes.

The Illusion preamp features a proprietary Current Audio Signal Transfer (CAST) connection to the iBias amplifiers to transfer audio signals in the current domain. CAST eliminates cable-induced signal loss and degradation, reduces noise and increases bandwidth. A complete Krell system consisting of source, preamp, and amplifier connected via CAST interconnects reduces the number of voltage-gain stages to one, delivering a noise floor that “approaches the theoretical limit of technology,” the company said.

President Bill McKiegan said the $7,000 Illusion II is the perfect mate for the $9,500 2x300-watt Duo 300 amplifier or the $7,500 2x175-watt Duo 175 amplifier, and the $15,000 Illusion is perfect for use with the 375-watt monoblock Solo 375 and 575-watt monoblock Solo 575 at $17,500/pair and $22,500/pair, respectively.
