Great products don’t just appear out of nowhere, they evolve, built on the foundations of things that came before them. The Boulder 2160 Stereo Amplifier replaces and surpasses in every way the venerable 2060, a brilliant amplifier that earned dozens of awards world-wide. All of the electronics have been updated with leading-edge technology while the look has evolved with style that is both subtle and elegant.
The 2160 remains uniquely Boulder. That is, it looks, feels, and sounds better than anything you’ve ever heard.
