Boulder 500 Series

There are any number of expectations you may have when thinking of a Boulder. The 500 Series aims to exceed these expectations in every way possible: sight, sound, and feel.

The 508 phone preamplifier is pure efficiency. As the smallest Boulder in more than two decades, the 508 packs an enormous amount of performance in a single, small chassis. A chassis that is carved from a single block of metal, no less. All of the proper inputs, outputs, and adjustments are here. As is the one constant from every Boulder product since Day One: a stunning level of performance.
