BALANCED AUDIO VK-80i Integrated
The long-awaited BAT VK80i integrated tube amplifier is characterized by a fully balanced architecture, which makes it's sound immediately and positively different from the competition. This high current, 55W output 6C33C triode design is based on the flagship REX 3, and introduces many of the BAT flagship amp's unique technological innovations.
6C33C-B Triode Output Tubes. Fully Balanced Signal Path
Delivering 55 watts per channel, VK-80i 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.
“Fuse-less” Protection Circuit
In the event an output tube becomes over-stressed, all you need to do is turn 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.
Intelligent Auto-Bias Design Makes Operation a Cinch
The advanced engineering within 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. 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 VK-80i sounds wonderful within the first few minutes of listening.
