For more than thirty-five years Boulder has been designing and building high quality audio components in Boulder, Colorado.

With an unrivalled reputation for sound quality and construction, Boulder electronics are cherished by audiophiles all over the world. Every single component must define its category and push the limits of what is possible in audio engineering, regardless of price point.

All Boulder products are made for the reproduction of music exactly as it was performed and recorded. Boulder electronics are transparent, accurate, fast, rugged and reliable, with minimal distortion and noise, and absolutely no colouration or “sound” of their own.

Reliability is a cornerstone and in this age of throwaway electronics, virtually every Boulder component ever shipped is still in use; indeed, most remain in the hands of their original owners.

We have always loved the Boulder products, but ever since we met Jeff Nelson and his team we have recognised soulmates in our journey: an entire company where everyone we talked to shared the same obsessive dedication to achieving audio perfection.

866 Integrated Amplifier – from £16,000


The 866 Integrated follows up on one of the most successful amplifiers in Boulder’s history, the 865, improving on the original in every way. Power is up to 200W per channel. Manufacturing is substantially more efficient. Weight has been reduced. New circuitry gives you greater current output at maximum power. External IP control has been added. And a dedicated Boulder app easily enables you to manage everything. If your system is made up of traditional components that still satisfy, the all-analogue version is exactly what you need.

Analogue & Digital

Modern technology is defined by flexibility. Here, you will find all the capabilities of the more traditional analogue version and much more besides. Much music delivery is now taking
place via network storage and Internet connections, while at the same time there are more traditionally connected sources than ever before. Because of this, the 866 features a full array of
available digital inputs that allow every type of connection, from satellite receivers to USB memory sticks to wireless subscription streaming and everything in between, to sound their
absolute best. Throughout the entire digital process, the data is up-and-oversampled to maximise the data rate to the DAC chips and reduce distortion to the lowest possible levels. Even further, Boulder has equipped the 866 to be a Roon® endpoint.

““I had very high expectations for this new launch of the 1100 series and frankly my expectations were exceeded. When a manufacturer builds to such a high-quality level that it takes over a decade to surpass their previous versions that says volumes about what an audio consumer can expect when the gear gets home.

Boulder Amplifiers’ ability to manufacture everything in their factory provides the highest level of quality control.”
