Balanced Audio Technology VK-80i Integrated Amplifier

Fully balanced triode architecture, automatic bias, high-current 6C33C-B power tubes

The graceful industrial design is based on BAT"s flagship REX 3 system, and incorporates many of that's series' technological advances.

Delivering 55 W per channel, the 6C33-B triode output tube offers many times the current delivery of the 6550/KT90 variants usually used in tube amps. This means you get the natural harmonic texture and instrumental timbre of triode design with no loss to bandwidth and dynamics, offering finesse, inner detail, and scale.

“Fuse-less” protection circuit for enhanced sound and user-friendly operation
In the event an output tube becomes over-stressed, all you need to do is turn the VK80i off and on again to restore normal operation. The elimination of internal channel and tube fuses contributes to a greater sense of ease and more natural reproduction of music. 

Intelligent auto-bias design
The advanced engineering within the VK80i 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 VK80i 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 sum of this engineering excellence is an amplifier with the midrange clarity, power, and dynamics that have made BAT one of the most respected brands in high-end audio.

An all-metal remote control is included.
