Boulder 865 Integrated Amplifier 

Based on the 810 Stereo Preamplifier and the 860 Stereo Amplifier, the 865 Integrated Amplifier includes preamplifier features normally reserved for much more expensive equipment. A discrete-resistor step volume control, first developed for Boulder's 2010 Stereo Preamplifier, allows precise 0.5 dB level adjustment-even with the remote. Full-balanced, differential, three-stage input circuitry results in ultra-low distortion and noise.

A large, dimmable alpha-numeric display provides easy to read information for status and control, even at a distance. A home theater bypass circuit for multi-use systems, individual input programmability for source level matching and setup, and selectable fixed or variable auxiliary balanced outputs assure exceptional system flexibility.

Additional control is provided by Boulderlink connections for complete system monitoring, an IR input for external control system integration, and by a 12V trigger for remote amplifier turn-on. Nevertheless, the 865 is not difficult to use. But the preamplifier section is only the beginning. The 865's output stage is a formidable source of power for any loudspeaker. Capable of 150 watts per channel, the 865 Integrated punches its way through the most spirited and demanding passages, while gracefully revealing the subtle details that make music astonishingly spacious and infinitely involving. Rugged binding posts require no tools for tightening and provide a secure, low-impedance connection for optimal power transfer. A precise bias control system monitors the output section and keeps the amplifier within its ideal operating range. Finally, the 865 is safeguarded by thermal limiting and over-current sensing circuitry which provide it with rock solid reliability without the slightest effect on sound quality.

The 865 Integrated Amplifier combines convenience and exceptional performance in a single component. Meticulously crafted to solidify the relationship between listener and music, its ability to create this connection is reflected by laboratory measurements in concert with the pleasure experienced by the most critical ears. Boulder has finally given you the opportunity you've been waiting for. If you’ve been dreaming of owning a Boulder, your audition awaits.
