Boulder 2120 DAC

There are now more ways than ever to enjoy your favorite digital audio and video media. There are also more ways to receive it. And the Boulder 2120 Digital-to-Analog Converter is set up to address them all. Its architecture is modular to help prevent future obsolescence. It can connect to streaming, server, or transport based audio in both PCM and DSD. It has become the source component that can play high-definition wireless streaming video to your AV system. All of this and the 2120 is still the best sounding D/A converter you’ve ever heard, too.
