Boulder Stereo Amplifier 2160

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 worldwide. All of the electronics have been updated with leading-edge technology while the look has evolved with a style that is both subtle and elegant.

2160 remains uniquely Boulder. That is, it looks, feels, and sounds better than anything you’ve ever heard.

 

  • Bias operation is Class-A to full rated output power and managed with an analog circuit that minimizes heat and power consumption

  • Boulder’s most powerful, continually produced stereo amplifier: 600W per channel

  • Surface-mount circuit board design minimizes connection resistance and leads inductance

  • Non-resonant chassis carved from solid blocks of aluminum on Boulder’s own CNC machining centres

  • Four fully-discrete 99H2 gain stages, potted and housed in machined shells for thermal stability and shielding

  • Two massive transformers are filtered, potted, and enclosed in a welded steel case

  • Power cycling, turn on sequencing, and status messages sent to Boulder preamplifier displays via the Boulder Link communication system

  • 12V trigger connection for remote turn-on and use with most surround sound processors and external control systems

  • Supervising microprocessor circuitry controls and monitors protection systems, and the turn-on and turn-
