The Maestro of KR amplification; perfect for any KR amplifier. With house manufactured tubes, remote and available phono-pre. Simple and sonically near perfect.
Our Amplifier Dichotomy:
has been choosing between lower powered vacuum tube amplifiers and higher powered reference transistor amplifiers and thus peregrinating between the two. Exposed to everything from the most expensive to commercial samples of both yet still the dichotomy exists; until now. KR Audio has all the power needed to play big classical correctly, house and techno music, classic rock, classic-strings and vocals: it is this flexibility that make KR and Absolute reference point. Another huge advantage to KR is fewer tubes are required to produce massive power: and the giant tube itself is a piece of industrial artwork!
Stop looking at lower powered tubes and forget solid state. Nothing beats the nearly religious experience of seeing and hearing a glowing pair of tubes in your system. KR audio provides the best possible tube experience with big volts and amperes; KR Audio is the new Master-Class of audio amplification.
A little about KR Audio:
KR Audio Electronics is located in Prauge, Czech Republic is a manufacturer of hand-crafted, high quality tubes (all glass is hand blown) and audio equipment. Our company began the research to make improved triodes in 1992 and started its life as a tube manufacturer, first with the historic Marconi valve reproduction and then tubes for audio as an OEM up-grade option in hi-end audio amplifiers in 1994.
The success we found with our products is a direct result of the comparison between the hand-made KR tube and the mass produced tube made on 60+ year old tube machinery. Given the unique technology we have developed, KR was able to satisfy the marketing demand for a better 2 channel stereo for home listening. It has been said that nothing comes closer to live music than our sound reproduction.
A KR amplifier in the existing sound system or the application of a KR tube gives the listener increased dynamics, greater detail from the recording, be it vinyl or CD, and an almost tangible imaging. At present, we design and build 17 different tube amplifier models for all tastes in Hi-Fi including two completely solid state sets. KR continues to manufacture tubes and is the inventor of the Kronzilla, the KR T-1610 tube the largest and most powerful audio tube ever made, but also as industrial designers can make any audio output device. The tube division currently makes 12 models to cover most audio requirements for improved sound be it a normal up-grade or an innovative design.
