Know before you buy
These modules are industry-leading Class D components that provide exceptional power efficiency while maintaining extremely low distortion. They ensure the amplifier delivers a clean, transparent sound that remains accurate even at high volume levels.
Yes, the Stereo X is equipped with both XLR (balanced) and RCA (unbalanced) inputs. This allows you to connect it to a wide range of preamplifiers or DACs depending on your current system setup.
While the unit features a fanless, all-aluminum chassis designed for efficient heat dissipation, it is still best practice to place it on a stable surface with a few inches of clearance on all sides to ensure optimal thermal performance.
The bi-amp button is designed to optimize the amplifier's performance when using a bi-amplification configuration. It helps improve stereo imaging and soundstage precision by ensuring the signal path is correctly aligned for speakers that support separate high and low-frequency inputs.
No, the Stereo X is a dedicated power amplifier. It does not include a built-in DAC or volume control, so you will need to pair it with a preamplifier or a source component that has its own volume output.
The trigger input allows the amplifier to automatically power on or off when it receives a signal from a compatible preamplifier or processor. This eliminates the need to manually toggle the power switch every time you use your system.
