My father’s last hifi featured a Balanced Audio Technology CD player so I have soft spot for all things BAT.
The new fully-balanced VK-80i Integrated Amplifier ($8995) employs quad of 6C33C-B Triode Output Tubes which offer many times the current delivery of the 6550/KT90 tetrode and 55 Watts of output power — more current = better control of your speakers — while four 6SN7s do the initial driving.
The VK-80i, which comes in all silver or all black, offers 3x line-level RCA inputs, a pair of XLR inputs, and 4, 6, and 8 Ohm speaker leads for mating to your speaker’s needs.
You don’t to have worry about tube drift as the VK-80i offers Auto-Bias that adjusts for changing line voltage and aging tubes, with each output tube having its own dedicated bias circuit. The rugged-looking VK-80i measures 17″ W x 8″ H x 16″ D and weighs in at 45lbs.
