Every project has to begin somewhere. When our engineers began work on the Boulder 508 Phono Preamplifier they began with inspiration from the absolute pinnacle of vinyl playback: the 2008 Phono Preamplifier, easily the most celebrated phono stage of all time.

But that’s where the similarities end. Where the 2008 was pure excess, the 508 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.
