Know before you buy
The SE, or Special Edition, designation indicates that the unit is built with upgraded internal components. Specifically, it utilizes high-grade Teflon capacitors and precision metal-foil resistors to improve transparency and detail retrieval compared to the standard model.
This amplifier is designed to bridge the gap between technologies. It offers the dimensionality and musicality often associated with tube gear while maintaining the precise control, speed, and power delivery of a solid-state design.
The high-quality internal components, particularly the specialized capacitors, require significant signal throughput to settle and reach their full sonic potential. You should expect to play the unit for 300 to 500 hours before it achieves its intended level of clarity and tonal accuracy.
Yes, with a power output of 400 watts per channel and a bipolar output stage optimized for high current delivery, it is well-equipped to handle complex speaker loads. It provides the necessary current to maintain tight bass control and dynamic response even during demanding musical passages.
The hybrid design uses a FET front-end to manage voltage gain, which contributes to the amplifier's natural, detailed sound. This is paired with a bipolar output stage to ensure the unit remains fast, responsive, and capable of accurate tonal differentiation between instruments.
