Boulder 866 Integrated Amplifier with Streamer & DAC - Pre Owned

Very good condition. Purchased new in December 2022. Boxed and complete.

How do you follow up one of the most successful products in the history of a company? With a product that improves upon the original in every way, and the Boulder 866 Integrated does just that.

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. There are versions for traditional systems as well as modern streaming media users. And a dedicated Boulder app easily enables you to manage everything.

And here’s the best part: the sound is everything you would expect from a Boulder. It’s powerful, clean, clear, quick, and true to the sound of the original recording and the intents of the artists involved. In fact, there’s absolutely no reason not to take home an 866. It’s everything you could want and more.
