Boulder

861 Stereo Power Amplifier

$10,000

The Boulder 861 Stereo Power Amplifier delivers Boulder's balanced circuitry, wide bandwidth, and rigorous in-house construction in the compact 800 Series format. It is an especially natural partner for the 812 DAC Preamplifier where space is limited but control and transparency remain priorities.

  • 50 watts continuous per channel into 8 ohms
  • Balanced XLR inputs and high-current speaker terminals
  • Same 12-inch-square footprint as the 812
