Power corrupts. Absolute power corrupts perfectly. Boulder’s flagship is their largest, most powerful, and most luxurious product in over 30 years of design. These are Boulder’s premier power amplifiers. Few people will ever see or hear them and fewer still will be lucky enough to own them. And yet because of their very existence the limits of sound reproduction have been pushed further than ever before. At every step of their development, one fundamental objective was consistent: the pursuit of absolute perfection in sound quality. Mission accomplished.
Boulder 3050 mono power amplifier features
- Boulder’s biggest, most powerful, and highest performing amplifier, each built to order for its new owner
- Completely designed, manufactured, and hand-assembled at our facility in Louisville, Colorado
- 1,500 watt power output into any load means absolute clarity and control of loudspeakers
- Black granite and stainless steel base, cut to match the angles and footprint of both the left and right amplifiers
- Intelligent microprocessor control so amplifiers can automatically set proper turn-on sequence via Boulder Link and transmit any necessary information to a Boulder preamp’s display
- Every 3050 contains two of Boulder’s highest performing gain stages, the 99H, available only in 3000 Series products
- Full Class-A biasing to maximum output, managed with an analog circuit that reduces bias current whenever possible to increase efficiency and reduce heat
- 120 output transistors for unequaled damping and power delivery
- Four transformers per amplifier, each DC filtered, sealed in machined housings, and potted in a proprietary epoxy for silent operation
- Circuit boards are installed in aluminum mounting frames precisely machined to fit the board and sandwiched with a layer of damping material
- Left and right amplifier chassis are mirror-imaged and feature multiple surface angles to break up any reflected sound
- Differentially balanced, instrumentation-style input circuitry for ideal electrical interface with any preamplifier or source component
