There are projects like the Boulder 3060 Stereo Amplifier that contradict conventions and redefine striving for perfection. Attempts are made to push the boundaries of what is thought to be possible. These projects involve countless hours of research, experimentation, and hard work, with each step along the way creating small improvements. When accumulated, each of these small improvements means big leaps forward. They embody the concept of what it takes to be the very best and the results are breathtaking.
Just like the Boulder 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 Boulder's facility in Louisville, Colorado
900W per channel power output into any loudspeaker load
Each amplifier is shipped with a machined aluminum and polished stainless steel 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 mean unmatched control of any loudspeaker system
48 massive filter capacitors are part of an ultra-responsive, low-impedance power supply
Five power transformers, housed in machined cases and potted to absolutely eliminate any noise, vibration or hum
