Boulder 1110 Preamplifier

What is it that makes the 1110 Stereo preamplifier so special? It is something 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 around the world. It is, after all, a Boulder, and every Boulder is special.
