Kronzilla DX

About the Kronzilla DX

The KR Audio Kronzilla DX mono-block amplifiers are high-end single-ended tube amplifiers operating in pure Class A with zero feedback. Each mono-block delivers 100 watts RMS output power using two parallel T1610 triode tubes per channel. The design features a hybrid approach with solid-state input and driver stages combined with tube output stages, providing the warmth and tonal qualities of tubes with improved signal-to-noise ratio and lower hum. The amplifiers include an auto-biasing circuit and sleep mode for convenience and tube longevity. They dissipate significant heat (about 300 watts per channel) due to their Class A operation, making them suitable for larger listening rooms. Dimensions per mono-block are 38.5 x 41.5 x 55 cm, and each weighs approximately 37 kg. The frequency response spans 20Hz to 20kHz (-3dB), with selectable output impedance of 4 or 8 ohms. The Kronzilla DX was redesigned in 2005 by Marek Gencev, improving power supplies, transformers, frequency response, and noise performance compared to earlier models. The tubes come with a one-year warranty, and the amplifier is known for its linear accuracy and robust build quality.
