The Starkrimson integrated amplifier combines Orchard Audio’s existing BOSC™ amplification and PecanPi® DAC technologies into a single enclosure. The inputs are either USB or S/PDIF.

The integrated amplifier provides access to both the DAC outputs and amplifier inputs; this enables the connection of devices like digital signal processors (DSPs) and preamps between the two.

GaN Technology Transistors

Starkrimson uses gallium nitride (GaN) technology. GaN transistors are claimed to provide the following sonic/sound benefits over their traditional silicon counterparts: less harshness; cleaner highs; better transparency; and higher detail. This is because GaN transistors have increased slew rate, reduced ringing, faster switching, and faster overload recovery.
