3060

Stereo Power Amplifier

There are projects that contradict conventions and redefine striving for perfection. These attempts push the boundaries of what is thought to be possible. They embody the very concept of what it takes to be the best.

Just like the 3060.

Features

  • Production of the 3060 is extremely limited and every unit is built to order

  • All assemblies are completely designed, manufactured and hand-assembled at our facility in Louisville, Colorado

  • 900W per channel power output into any loudspeaker load

  • Each amplifier is shipped with a polished black granite base that is cut to match the footprint and casework angles of the amplifier

  • Contains four (two per channel) of Boulder's highest performing gain stage, the 99H

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

  • 60 bipolar output transistors per channel for unmatched control of virtually any loudspeaker

  • 48 filter capacitors are part of an ultra-responsive, low-impedance power supply

  • Five power transformers, each housed in a machined case and potted to eliminate any noise, vibration or hum
