Boulder 1110 Preamplifier

What is it that makes the 1110 Stereo preamplifier so special? It is rare, an overachiever, a unique combination of reference-level performance and compact, convenient design. It is at once familiar in size and shape and yet completely new in aesthetic design detail. Perhaps what makes it so special is that it takes such amazing sight, sound, use, and feel and packs them all into a single chassis. It is the perfect mix of traditional function and cutting-edge technology, earning more than 10 international product awards from media worldwide.

Boulder 1110 Preamplifier

Like the 1160 power amplifier, the 1110 preamp is a classic case of a “form follows function” design. Its appearance includes clean and lightly sculptured metalwork, minimal front panel controls, and a clean and highly readable front panel display. For all its technical advances, the Boulder 1110 is also very straightforward in function. It only has XLR inputs and outputs and basic control features on the front panel and remote. (The 1110’s manual remote is a small attractive unit with input, volume, balance, and polarity controls.)

It is, after all, a Boulder, and every Boulder is special.
