A high-performance sound had always meant separate components, a lot of cables and large space requirements. Simple, integrated solutions fell short of the mark when it came to sound quality. In short, convenience came with a compromise.
Until Boulder’s 865.
Massive, shielded, toroidal transformer and multiple filter capacitors for immediate power transfer
Efficient heatsink design means high power in a small chassis without excessive heat
Four pairs of inputs, each capable of custom configuration and naming
One pair of auxiliary outputs that can be set for fixed (to drive secondary systems) or variable operation (to drive a subwoofer or additional amplifier)
Fully balanced input circuitry for maximum resolution and sound quality
Rugged, easy-to-connect, high-current speaker terminals require no tools
Boulder's own precision stepped volume control, the same as in the 2010 preamplifier
Input and preamplifier sections are housed in steel casework to eliminate interference from other portions of the amplifier
Supervising microprocessor controls all preamplifier functions, monitors protection circuits, and communicates with other Boulders
