Know before you buy
The T1610 is a proprietary KR Audio power triode designed specifically to handle high current, allowing the amplifier to deliver 35 watts of pure Class A power. These large-format tubes are central to the Kronzilla's signature rich, detailed, and expansive soundstage.
Yes, the zero-feedback design prioritizes natural harmonic structure and transient speed over the strict damping factor found in many solid-state amps. It performs best with speakers that have a relatively stable impedance curve and moderate to high sensitivity.
The Kronzilla SDi features selectable speaker impedance taps on the rear panel. You can toggle between 4 and 8 Ohm settings to ensure an optimal power transfer and impedance match for your specific loudspeaker load.
Due to its substantial weight and the heat generated by Class A tube operation, you must place the amplifier on a sturdy, vibration-resistant rack or stand. Ensure there is at least 15–20 cm of open space above and around the unit to allow for proper heat dissipation.
The Kronzilla SDi is designed exclusively with RCA inputs. If your source components only have balanced XLR outputs, you will need to use high-quality RCA adapters or cables to connect them to the amplifier.
As with any high-performance tube amplifier, the T1610 tubes will eventually require replacement based on your usage habits. You should also periodically check that the amplifier is kept in a dust-free environment and that the tubes are seated correctly in their sockets.
