    Boulder 3050 Monoblock Power Amplifier

    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.

    The Boulder 3050 represents the pinnacle of monoblock amplifier engineering, delivering 1,500 watts of pure Class-A power into any impedance. Hand-assembled in Boulder's Louisville facility, each unit features 120 output transistors for exceptional damping and speaker control, paired with dual 99H gain stages exclusive to the 3000 Series. Four individually filtered and potted transformers ensure silent, stable operation, while differentially balanced instrumentation-grade inputs guarantee optimal compatibility with any source. Mirror-imaged chassis with precision-machined aluminum board frames and damping layers minimize resonance and reflections. Intelligent microprocessor control enables seamless Boulder Link integration and automatic turn-on sequencing. Built to order with black granite and stainless steel construction, the 3050 combines uncompromising performance with meticulous craftsmanship.
