Know before you buy
The Mk.II revision features a completely redesigned power supply and upgraded transformers. These improvements result in a more refined frequency response and a lower noise floor compared to the original model.
The Kronzilla DX Mk.II is designed with selectable 4 and 8 Ohm output taps to accommodate a wide range of speaker impedances. However, because it is a pure Class A, zero-feedback design, it performs best when matched with speakers that have a relatively stable impedance curve.
The T1610 is a proprietary KR Audio tube capable of delivering high power while maintaining the sonic purity of a single-ended design. Using a parallel pair per mono-block allows the amplifier to reach 100W RMS, providing the dynamics of a high-power amp without sacrificing the nuance of tube amplification.
Yes, as pure Class A amplifiers, these units generate significant heat during operation. You should ensure they are placed on a sturdy, open-air surface with plenty of ventilation space on all sides to allow for proper thermal dissipation.
Each unit measures 38.5 x 41.5 x 55 cm and weighs approximately 37 kg. You will need a substantial, heavy-duty equipment rack or dedicated floor space that can support the weight and accommodate the large footprint of both units.
Zero-feedback designs are prized for their natural, open sound and lack of the artificial 'tightness' often introduced by negative feedback loops. While this results in a highly musical and transparent presentation, it requires careful system matching to ensure the amplifier maintains control over your specific speakers.
