Orchard Audio Starkrimson Stereo Ultra

Starkrimson amps are state-of-the-art (SOTA) hi-fi audio power amplifiers that were conceptualized to provide the listener with a truly life-like musical experience, presented with every significant detail intact, in order to convey an emotional connection to the music.

Starkrimson Ultra amps utilize gallium nitride (GaN) technology to achieve ultra-high performance. Learn more about the technology, at this link.
