Boulder 3050 (pora)

Power corrupts. Absolute power corrupts perfectly. The Boulder 3050 Mono Amplifier, our flagship, is our most powerful, largest, and most luxurious product in over 30 years of sound system design. These are Boulder’s premier power amplifiers, the unequivocal peak of our abilities. 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. Even Robb Report magazine acknowledged their superiority with their Best of the Best award.

At every step of the 3050s development, one fundamental objective was consistent: the pursuit of absolute perfection in sound quality. Mission accomplished.

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

Aluminum 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
