Boulder 866 Integrated Amplifier
The 866 is Boulder's flagship integrated amplifier, an advance on its predecessor with more power delivered at lower weight and cost through manufacturing efficiencies.
It delivers 200W per channel through new circuitry that allows higher current at maximum power, and is offered as an all-analog model or with added digital streaming over USB, Ethernet, AES3, Toslink, AirPlay, and Roon.
Its circuit boards and metalwork are produced entirely in-house, and it is controlled through a full-color touchscreen or a companion mobile app with customizable source labeling.
Price shown is the base analogue-only configuration; the digital and streaming version costs more. Confirm current pricing for the configuration you want before ordering.
