Boulder – 2120

Product Description

Boulder – 2120 digital to analog converter.

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 2120 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.


Supports all common digital data rates and resolutions.

Decodes MP3, FLAC, xFLAC, WAV, xWAV, ALAC (Apple Lossless), AIFF, OGG Vorbis, and DSF (DSD 1x and DSD 2x) music files.

Accepts streaming (USB and UPnP/DLNA Ethernet) and traditional (HDMI, Toslink, S/PDIF and AES3) digital input connections.

Artist, track name, album name, cover art and file type information is displayed when available during streaming.

Plays online audio and video services such as Tidal, Spotify, Netflix or YouTube via HDMI inputs, including video throughput.

Four isolated chassis: left audio, right audio, user interface, and power supply.

Full selection of optional digital input modules can be chosen to fit any system needs.

Uses 20 fully-discrete 993S gain stages, a modern descendent of the 990 gain stage used in broadcast and recording studios world-wide.

Dual standby modes (normal and low power options) to meet all energy efficiency requirements.

Comprehensive function and display setup modes to tailor the 2120 to the user’s preferences.

Differentially balanced version of Boulder’s Precise Interval Clock to eliminate jitter and maintain ultra-precise data timing at the DACs.

IR remote and networked IP control for use in stand-alone systems or fully integrated homes.
