boulder preamplifiers & phono preamplifiers
The 3010 Preamplifier is easily the greatest performing preamplifier in the history of the company. It’s also the most flexible preamp we’ve ever designed.
Separate enclosures for left and right analog sections keep all control and power circuitry from affecting sound.
Separate power supply chassis with individual supplies for left channel, right channel, preamp control, and low-power Standby mode
Large, full-color, 14.9-inch (38 cm) LCD display clearly indicates all controls, settings, and audio paths.
The 2110 Preamplifier is Boulder’s most iconic offering. It is instantly recognizable, our highest performing, continuously-produced preamplifier.
Four separate chassis: left audio, right audio, user interface, and power supply to isolate the analog channels from supply, control, and display noise.
Six pairs of programmable, differentially-balanced inputs. Three pairs of balanced outputs for bi- and tri-amplified systems or powered subwoofers.
Uses 12 high-current output 993S gain stages, a discrete and modern version of the 990 gain stage used in broadcast and recording studios world-wide
The 2108 Phono Preamplifier. Three pairs of balanced inputs allow connection to three different turntable, tonearm, or cartridge combinations at the push of a button, without any reconfiguration.
Entirely separate power supply chassis houses four independent power supplies: left audio, right audio, control, and standby, for total isolation of all supplies from the sensitive analog audio circuitry.
Standard RIAA equalization as well as EMI, FFRR (London/Decca), and Columbia EQ selections enable proper playback of collectible records made prior to 1955.
Front panel selectable, three-setting low-cut filter removes turntable rumble or low frequency noise from warped records.
The 1110 Preamplifier. Five pairs of programmable, differentially-balanced inputs. Large, easy-to-read, LCD display.
Balanced version of Boulder's own analog volume control, descended from the 3010 Preamplifier, for superior clarity and noise elimination.
Dual-mono audio boards isolate left and right channels for perfect stereo separation in a single-chassis design.
Boulder's own 983 gain stage means excellent buffering and current drive for long cable runs
Two pairs of balanced inputs on the 1108 Phono Preamplifier for systems with more than one turntable, cartridge, or tonearm. Fully-balanced input circuitry to take advantage of a phono cartridge's naturally balanced output.
Gain settings of 70 dB (MC) and 44 dB (MM) enable use with virtually any phono cartridge. Flexible resistive and capacitive cartridge loading and setup (MC and MM) via removable rear panel Personality Cards.
Traditional RIAA equalization as well as EMI, FFRR (London/Decca), and Columbia EQ settings for LPs made before 1955.
Two pairs of balanced outputs to connect preamplifiers and recording devices at the same time.
The 812 Preamplifier can be used just as a preamp, a DAC, a headphone amp or any combination of the three. With all the features and its versatility, the 812 is perhaps the highest value product Boulder has ever produced.
Two pairs of balanced analog inputs. One pair of balanced analog outputs. Two Toslink optical inputs, one coaxial input and one USB-B input. Streaming capabilities, Roon endpoint, UPnP playback, Air-Play functionality and Bluetooth.
Easily switch between headphone and preamp mode with the output exchange button. Stylish headphone bay cover to keep dust out of headphone jacks.
The 508 Phono Preamplifier is the smallest Boulder in more than two decades; nevertheless the 508 packs an enormous amount of performance in a single, small chassis.
Balanced inputs mean the perfect interface with the balanced output of phono cartridges. Balanced outputs to minimize distortion and drive long cable runs with no loss of fidelity.
Simple selection of MC or MM modes via switch on the rear panel. Integrated low-cut filter removes excessive low frequency information from warped or damaged records.
Elegant casework carved from a solid block of aluminum.
