Know before you buy
GaN technology allows for significantly faster switching speeds compared to traditional silicon transistors. This results in greater precision, improved transient response, and higher efficiency, which contributes to the amplifier's transparent and lifelike sound quality.
No, it does not. Despite delivering high power output, the amplifier is designed to be highly efficient, meaning it produces very little heat even when driven hard. You won't need to worry about ventilation space as much as you would with a traditional Class-A amplifier.
Yes. The amplifier is 2-ohm capable and 1-ohm stable, making it robust enough to drive even the most demanding, low-impedance speakers without struggling or losing control.
The unit features internal circuitry that converts incoming RCA signals into a true balanced signal. This ensures you maintain the benefits of the fully balanced architecture regardless of whether you are using RCA or XLR cables.
The Starkrimson Stereo Ultra 2.5 outputs 250 watts per channel into 8-ohm speakers and doubles that to 500 watts per channel into 4-ohm loads, providing plenty of headroom for most high-end speaker systems.
