Balanced Audio Technology VK-80i Integrated Amplifier

The Balanced Audio Technology VK-80i Integrated Amplifier delivers 55 watts per channel, and uses four 6C33C-B triode output tubes for power delivery. They offer many times the current delivery of the 6550/KT90 tetrode tube variant used in most traditional tube integrated amplifiers. In addition to driving even difficult low-impedance speaker loads, the all-triode fully balanced design provides a natural portrayal of harmonic texture and instrumental timbre. Your recordings will sound more alive while simultaneously yielding greater finesse, grace, and inner detail.

In the event an output tube becomes over-stressed, all you need to do is turn Balanced Audio Technology VK-80i off and on again to restore normal operation. That’s it. The elimination of internal fuses also contributes to a greater sense of ease and more natural reproduction of music. Also, the fuse-less protection circuit is combined with a world-class automatic-bias circuit that eliminates the constant need to set and readjust the proper bias of the output tubes. No tubes to bias. No tube fuses to replace.

The advanced engineering within BAT VK-80i eliminates the traditional headache associated with most vacuum-tube power amplifiers—specifically, the constant need to set and readjust the proper bias of the output tubes. The BAT VK-80i features an intelligent automatic-bias design that adjusts for changing line voltage and aging tubes, with each output tube having its own dedicated bias circuit. The auto-bias circuit also ensures your BAT VK-80i sounds wonderful within the first few minutes of listening.
