Our ex demonstration Boulder 508 phono stage is now available, and it’s offered complete with all packaging and accessories.
Every project begins somewhere. When Boulder’s engineers began work on the 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.
If you’re considering a premium phono stage then our ex demonstration Boulder 508 really should be on your list – please contact us if you’d like more information or to try it out for yourself.
