The Orchard Audio Starkrimson Stereo Ultra DMC 2.5 is a high-power, two-channel GaN Class-D power amplifier. It combines Orchard Audio’s high-frequency 0.8 MHz switching amplifier modules with a fully balanced signal path, independent power supplies for the left and right channels, and approximately 43,600 µF of upgraded power-rail capacitance per channel. Revision 2.5 adds an integrated active RCA-to-XLR converter, allowing both single-ended RCA and balanced XLR sources. The amplifier is designed for demanding loudspeaker loads, delivering 250 W per channel into 8 ohms and 500 W per channel into 4 ohms, with operation supported down to 2 ohms and stability specified to 1 ohm. It is a power amplifier and does not include a DAC, streamer, phono stage, volume control, or loudspeaker drivers. Available manufacturer information identifies the product as a current Orchard Audio model rather than a discontinued product.
