Boulder Amplifiers 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 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.

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 lead inductance

Non-resonant chassis carved from solid blocks of aluminum on Boulder's own CNC machining centers

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-off of any linked amplifiers

Dual stage design incorporates the majority of gain in the first stage to maximize bandwidth and minimize distortion

Two pairs of speaker connections per channel to accommodate bi-wired loudspeakers

Fully-balanced design from the inputs to the outputs substantially reduces distortion and noise
