Product Description

KA – L Reference Mk3 is our ultimate statement, with all of our knowledge and experience built into it. The best passive components that can be found on the market are being used in order to gain the best results possible, which contributes to the quality of sound, but also has positive influence on the reliability of Karan Acoustics amplifiers and preamplifiers. There could be no other way – as the central unit in an audio chain, it simply demands the best. Completely balanced, dual mono circuit topology, with 24k gold plated circuit boards, all stages are DC coupled and operate in pure class A. In order to achieve the best results possible it was necessary to divide the power supply into a separate casing, which brought its influence on the electronics to a minimum. In order to avoid the inherent nonlinearities of potentiometers, this preamp uses a four-gang attenuator, with 64 positions, implemented by using the highest quality vacuum relays and fixed value 0.1% tolerance metal film resistors due to the high sensitivity to interference of preamplifiers. The huge power supply has been relegated to a separate case of its own, and has been made ultra stable using four stabilization levels per channel. For vinyl lovers we can offer phono board which can be build into this preamplifier.
Using several newly developed proprietary solutions, this preamplifier yields absolutely no sonic colorations, huge soundstage, deep and tight bass and polite mids and highs.
