All parts of the 860 Stereo Amplifier, every piece of metal, every circuit, is created and assembled in-house by our own craftsmen and technicians. Boulder is the last high-performance audio manufacturer in North America to proudly hold this degree of quality control over our own designs.

  • Programmable Boulder Link to turn on multiple 850s and transmit their status to any Boulder preamplifier's display

  • Supervising microprocessor oversees all functions and communicates with Boulder preamplifiers

  • Two-stage design provides most of the gain in the first stage, thus maximizing bandwidth

  • Advanced protection circuits for trouble-free operation

  • Precision surface mount circuit boards minimize connection resistance and inductance

  • Rugged, easy-to-connect, high-current speaker terminals require no tools

  • 16 output transistors provide stable operation with practically any loudspeaker

  • Potted and magnetically shielded power transformer for quiet operation

  • Multiple filter capacitors assure a low impedance, distributed power supply
