Boulder Amplifiers, Inc.

Boulder Amplifiers, Inc. Founded in 1984, Boulder manufactures the world's finest high-performance home audio electronics. We are not a virtual company.

After over 30 years in business, innumerable people know Boulder’s products but very few know the company. Not only are the electronics—widely considered the finest home audio products available in the world—unique amongst their competitors, but the company itself has an origin that is significantly different and more substantial than other players in the high-performance audio industry. Boulder w

as officially incorporated in 1984, though the company’s story goes back well before then, when the principle designers were based in San Diego, California and immersed in the professional recording studio and broadcast industries. Since that time, the company has grown at a measured pace that reflects both diligent management and our dedication to creating the best home entertainment products we’re capable of producing. Throughout our history, one thing has never changed: our unwavering dedication to hand-building the most accurate and reliable audio components in the world. Boulder is not a hobby business or well-funded but technologically hollow startup. We are an organization with a traceable lineage firmly grounded in engineering and technology. Everything is designed and manufactured at our new facility in Louisville, Colorado in the U.S. We’ve attempted, whenever possible, to bring every aspect of the manufacturing process under our roof in order to improve our quality control. We do not outsource design or production. All of our products are the handiwork of multiple engineers, metalworkers, technicians and craftsmen who take great pride in being a part of the last truly high-end audio company in North America that is independent and does everything in-house. While this method of manufacturing may cost a little more, it is the only way we know of to guarantee absolute perfection in performance, reliability and quality. Our founder, Jeff Nelson, is fond of asking, “Doesn’t anyone really care about the customer anymore?” We ask this of ourselves everyday. As long as there are music and film lovers who understand and appreciate what we do, we’ll continue to make the home sound and cinema event an experience unequalled by any other means. This devotion and adherence to our core values has earned us dozens of awards and accolades over the years. Yes, they look nice in our trophy room, but in the end our greatest judge is you, the listener.

More than twenty years separate these two amplifiers, but they share the same goal: delivering exceptional musical performance.

When the 850s were introduced in 2005, they represented the very best of what we could achieve in a chassis that size at the time, and earned their place in numerous systems around the world.

Fast forward over two decades, and the new 851s are the result of everything we've learned since then. Thousands of hours spent engineering, listening, and refining, have culminated in a product that builds upon that legacy while raising the bar for what's possible.

Technology evolves. Components improve. Our understanding deepens. But one thing has remained constant: our commitment to creating products that connect listeners with their music.
Looking at and listening to these two amplifiers side by side is a reminder of just how far we've come—and we're excited about where the journey leads next.

We have been having a lot of fun showing off the new 800 series on the 3rd floor of the Vienna High End Show. But we didn’t forget to bring the big stuff too. Check out the Boulder 2160 and 2110 with the new Ymir in H X2, C03/D02 on floor -2!

The 851 monos are the newest amplifiers from Boulder. Delivering peaks of 150 watts per channel into 8 ohms. It is also doing it in pure class A using the Smart Current designs we developed in the new Boulder 1100 series amplifiers. There is a lot of performance and punch in this compact chassis that we think will surprise most. As you can see, we couldn’t add more to this box if we wanted!

Be the first to hear the 851s as we debut the 851 monos on a pair of YG Hailey’s in Room 3.83 at Vienna. No worries if you cannot make the show, these amps will start shipping to your local Boulder partners as soon as next week. If you don’t know where your closest Boulder partner is, please reach out to us through Boulderamp.com or our email [email protected].

Happy listening.

The 808 is the newest phono stage in Boulder’s lineup. The 808 takes lessons and experience learned from 40 years of designing phono stages and puts them in a compact chassis that matches the look and multifaceted perks of the rest of the 800 series products. Sharing some of the design philosophy of the 2 phono preamplifiers in the higher line-ups, it improves on the 508 in terms of listening and functionality. Rethinking shielding, ground schemes, and signal path, resulting in an improved sonic performance. It is also more flexible in use by allowing for cartridge loading with a set of ‘Personality Cards’, a mono switch, and a low-cut filter switch.

We are excited to have the world premiere of the 808 at High End Vienna. It will be paired with a Innovation Compact turntable, Boulder 812 DAC preamplifier, and the new Boulder 851 Monos powering Hailey’s.

Better yet, we are excited to have Jason Ford doing an hour presentation each day in our room. He will be showing an incredibly rare selection of pressings through this system you won’t want to miss.

Come experience the system and some music you won’t hear anywhere else.

Times for Jason’s presentations are:

Thursday the 4th June - 4:00 pm
Friday the 5th June - 3:00 pm
Saturday the 6th June - 3:00 pm
Sunday 7th June - 2:00 pm

All in room 3.83

See you there.

We are excited to announce 2 new products in the 800 series! We are also excited that we will be showing these at High End Vienna next week. Visit us in rooms 3.81 and 3.83 to see and hear these for the first time!

-808 Phono Preamplifier- A phono stage in the 800 series, which is a step up from the 508 and allows for customizable cartridge loading, much like the 1108 and 2108. Toggleable mono and low cut switches.

-851 Mono Amplifier- A 100-watt per channel amp utilizing the Smart Current pure Class A that we use in the 1100 series, but in the same size package as the 861 stereo and 812 DAC preamplifier. The most powerful ‘travel-sized’ Boulder created to date. After first listening, many of the employees and engineers wanted a pair for themselves, and we are excited to finally show them off.

Check out Boulderamp.com for the rest of the specs and literature. These will start shipping worldwide right after the Vienna High End show. Looking forward to seeing you there or afterwards at your favorite local retailer.

Happy Listening.
