BAT Supertube Unistage integrated


Karma-AV is introducing Balanced Audio Technology’s hybrid VK-3500 integrated amplifier to UK audiophiles. The VK-3500 marries a ‘SuperTube Unistage’ preamplifier with a solid-state power section generating 150 watts per channel and doubling that into 4 Ohm loads. 

In the 6H30 SuperTube Unistage the signal is transmitted through only one gain stage with zero feedback. The VK-3500’s revised preamp topology uses 2nd generation oil capacitors chosen to reduce ‘ringing’ artifacts, and deliver more organic, natural sound. The VK-3500’s output stage employs a zero-feedback symmetrical bipolar design said to provide high current capability as well as wide bandwidth “for the ultimate in transparency and high-end extension”.


From the machined-aluminium remote control, a programmable user interface provides for one-touch source/polarity switching and volume control. The integrated phono module accommodates both moving-magnet and low-output moving-coil cartridges. Inputs include two balanced (XLR) and three single-ended (RCA), with RCA and balanced preamplifier outputs also provided. Typical UK pricing inc VAT: £12,995.00. Availability: June 2021.
