  4. Boulder 3050 Monoblocks

    Boulder 3050 Mono Power Amplifier

    BOULDER 3050 Ultimate Monoblock Amplifier

    Boulder has been unrivaled in defying expectations and limitations for nearly 30 years. From our earliest days creating studio equipment used in the making of some of the world’s most important recordings, to now, with our groundbreaking use of UPnP technology raising the bar for streaming digital audio. At every step of the way, one fundamental objective has been consistent: the pursuit of absolute perfection in sound quality.

    Most companies have a pipe dream, a product they would build if the time were right and the customers were there, if there were no limits, if a new benchmark could be achieved.

    Practically nobody builds this kind of product. Many claim to, but careful scrutiny nearly always reveals compromises or cynicism in the results. The challenges involved in creating a true statement piece are monumental, and the few who make the attempt are rarely able to say with honesty that they wouldn’t change a thing.

    But not here. At Boulder, a dream has become reality. The reaction from journalists, industry insiders, enthusiasts and casual listeners has been nothing short of shock.

    The 3050 Mono Power Amplifiers have arrived.

    They had the best starting point—the design experience benchmark from the 2050 Mono Amplifiers. The new task for our engineers was clearly defined: more power, a new look and greater performance. It called for everything we knew as an electronics manufacturer: ideas, passion, research and dedication. Take it all and surpass it. Make it better. Exceed even what we thought was possible.


    To increase power output, the output section and the supplies that feed it were reviewed and improved. Distortion was lowered with the development of an entirely new gain stage, the 99H. Mechanical isolation was taken to fanatical levels. Power requires a dedicated 240V circuit. Even the audible thermal signature of electrons passing through conductors was taken into account. All to produce an amplifier with such incredible levels of superiority that it defies categorization. The proof? A continuous 1,500 watts into any load. Current output great enough to drive any loudspeaker ever built. Distortion levels so low (0.0017%) that the coloration of every component in the chain outside of the 3050 will be audible. It is capable of perfectly recreating massive, thunderous crescendos. And yet, despite its awesome power, when asked to do so, the 3050 remains delicate, spacious and refined.

    The sound of the amplifier itself cannot be described because the 3050 has no sound of its own. Bass, mids, highs, soundstaging, resolution, transparency, liquidity, musicality, realism, separation, pick your cliché: Everything is better. The select few in a position to own the 3050 Mono Amplifiers will enjoy events that may never be surpassed by anything but a live performance.

    Even the exterior has reached a new level with a new design, faithful to all of the familiar Boulder hallmarks, but taken in a new direction. Countless ideas were developed, explored and rejected. Hundreds of drawings were rendered. Even something as simple as the pushbutton on the front panel was reworked and refined to a degree that would seem outrageous for any other product. But the results speak for themselves: The appearance of the 3050 is absolutely stunning. It’s cut from a very different cloth. It’s not just the sheer mass of the 3050 that grabs your attention (a behemoth at 445 lbs.), but the stance. The overwhelming scale of the parts is immense, but that’s the point. They perfectly represent the immense performance this amplifier achieves.

    To consistently be at the very top, there are many things you must always possess: Unwavering discipline. Drive and dedication. Unwillingness to compromise. Creativity. The ability to reject traditional boundaries. A refusal to say, “That’s good enough.” These virtues are at the very heart of the 3050. Because to you—and to us—these values mean everything.

  5. Boulder 3060 Stereo Power Amp

    Boulder 3060 Stereo Power Amplifier

    BOULDER 3060 Dual Mono Ultimate Stereo Power Amp

    There are efforts that contradict conventions and redefine the idea of striving for perfection. With innovative technologies, intelligent construction and an unmistakable design. With enough experience, these efforts are not unusual but become second nature. The 3060 Class A Stereo Power Amplifier is one of these efforts.

    Boulder is not a startup and is not a virtual company. We have a real history. For us it is never enough to simply fill a market niche, to create a product solely for the purpose of giving someone something expensive to buy. Every single Boulder must define its category and push the limits of what is possible in audio engineering. Regardless of price. Our latest endeavor is the 3060. Built to our standards, which means that it is built like nothing else on earth.

    The 3060 is heavy. 440 lbs/200 kg. Yes, the casework is cut from massive pieces of 6061-T6 aluminum. Yes, it has five transformers. It has 120 output devices. It has 48 output filter capacitors. It has all of the things you would expect from Boulder’s largest stereo amplifier and it has more. More parts, more control, more finesse, more of everything. Specifications and numbers are often used to impress and baffle (and possibly intimidate) a potential customer. We would prefer to tell you what we do rather than how much we do it.

    The 3060 is dramatic to view. It has a presence all its own. There are no corners that meet in a 90-degree angle. The heatsink slots are huge. The Colorado granite-and-stainless steel base grounds it. Yet the front panel has only a single, elongated button to terminate the front panel angles, lending the amp a stately elegance. For those who have been lucky enough to view the 3060 next to its larger brethren, the 3050 Mono Amps, it is a combination of the separates and yet it is still its own design.

    The 3060 is peace of mind. Every supply is monitored and protected. Every variable is accounted for. All pieces of the amplifier, every piece of metal, every circuit is created and assembled in-house by our own craftsmen and technicians. Boulder is the last audio manufacturer in North America to hold this degree of control over our own designs, but it’s worth it.

    The 3060 is an immensely powerful amplifier. This means it will control every movement of your loudspeakers so as to reproduce exactly what was encoded in the recording. From the largest explosive crescendo to the tiniest, wispy detail. And everything in between. If it was captured on the microphone it will come out of your loudspeakers the exact same way, unaltered and unchanged. But power alone is not the goal. No other stereo amplifier will provide you with the same emotional experience, the same immersion, the same thrill.

    Because no other amplifier is a 3060. Now you can experience it where it can put its strengths to good use: the heart of the finest audio systems in the world.

  6. Boulder 850 Mono Power Amplifier

    Boulder 850 Mono Power Amplifier

    BOULDER 850 Monoblock Amplifier

    At first, the 850 seems very different. Its appearance is simple and the complete chassis is only one-half as wide as a traditional amplifier. This uniquely small footprint lets it work ideally in places where conventionally sized monoblocks won’t. Upon closer inspection, though, the 850 is most certainly a Boulder. Its diminutive size belies a muscular powerhouse of an amplifier: The 850 can provide 200 watts of continuous output into any load for immense control during even the wildest musical swings. Play something dynamic and you’ll hear this authority at work, providing the kind of rhythmic response you get lost in with the energy of foot-tapping music.

    Even more impressive, the 850 accomplishes this delivery of power while maintaining refinement, delicacy and nuance. The very intent of the performers is conveyed. Layer upon layer of the music’s information and detail become apparent, even in recordings you’ve heard hundreds and hundreds of times before.
