Boulder Amplifiers 1108
Power. Finesse. Extended frequency response. Speed. Delicacy. Control. Spaciousness. Precise imaging. Rhythm. Dynamics. Involvement. Musicality. The list goes on. Selecting only a few of these traits and asking any audio product to achieve them is quite a daunting task. Looking at the list and then listening to the 1108 Phono Preamplifier, it immediately becomes apparent that it can do all of them. With ease.
For quite a lot of people, vinyl or phono playback was the first time they had heard of Boulder. The degree to which our phono preamplifiers pushed the limits of analog performance forward was shocking to many and it drew quite a lot of attention. Decades later the 1108 is doing it all over again. With ease.
Two pairs of balanced inputs for systems with more than one turntable, cartridge, or tonearm
Traditional RIAA equalization as well as EMI, FFRR (London/Decca), and Columbia EQ settings for LPs made before 1955
Low-cut filter to eliminate low frequency noise caused by turntable rumble or damaged LPs
Fully-balanced input circuitry to take advantage of a phono cartridge's naturally balanced output
Flexible resistive and capacitive cartridge loading and setup (MC and MM) via removable rear panel Personality Cards
Proprietary 985 gain stage is engineered specifically for the 1108 and encased in a housing machined from a solid block of aluminum
Gain settings of 70 dB (MC) and 44 dB (MM) enable use with virtually any phono cartridge
Interlocking casework damps vibration and shields the delicate analog phono signal inside
Two pairs of balanced outputs to connect preamplifiers and recording devices at the same time
