About the 2120
The Boulder 2120 is a high-end DAC/streamer from Boulder’s 2100 Series. It combines digital-to-analog conversion, network streaming, and a digital preamp/volume control in a modular, four-chassis architecture with separate left channel, right channel, logic/interface, and power supply sections. The 2120 was introduced around 2015 and is still referenced in Boulder’s current product history, but it appears to be discontinued or no longer in active production.
