Linear Audio Research will introduce its VIADUA amplifier alongside KATE loudspeakers at Audio Video Show Warsaw 2026. The Linear Audio Research VIADUA is a single-ended vacuum tube amplifier delivering 17W of output power, priced at €8,000.
KATE is the Polish company’s first mass-produced loudspeaker. It is a two-way design with an MTM, or midwoofer-tweeter-midwoofer, configuration using two 165mm drivers and a soft-dome tweeter positioned in a small waveguide. The drivers are supplied by Kartesian.
The loudspeaker uses internal wiring manufactured by NxLT, short for Next Level Tech, and anti-vibration bases supplied by Franc Audio Accessories. KATE will cost no more than €10,000 in the high-gloss lacquer finish.
Both products will be presented in Room 323 at Hotel Sobieski during the show, which takes place from 23 to 25 October 2026. Linear Audio Research’s amplifier manufacturing history extends back 51 years before this year’s event. The company adopted its current name in 2002.
