Not only does it sound better, but it's more powerful, stylish and affordable than its predecessor, and with the option to add a DAC, this is a real winner.
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.

The sound. What can I tell you about the sound? It’s not great. By which I mean that it’s excellent… extraordinarily good, in fact. So exceptionally good that you won’t have to spend hours in lengthy listening sessions, auditioning track after track after track in order to establish its quality: you’ll know in the first few instants that you’re listening to a remarkable amplifier. For starters, the 866’s control over bass is exceptional. If you thought your speakers delivered tight, taut and rhythmic bass, you won’t really have heard them until you’ve connected them to Boulder’s 866. The tonal quality, the depth of the bass, the perfect pacing of bass lines, the dynamism revealed by the sound from a close-miked drum kit… the Boulder 866 has it all in spades. No, it’s better than just spades, it’s a full lay-down misère.
