Boulder – 2108 Phono Preamplifier

In 2002 Boulder released the 2008 Phono Preamplifier. At the end of that year, it was placed in the A+ category of Stereophile magazine’s recommended components, a category created for electronics that are so far ahead of their peers that they justify an entirely new classification.

And now Boulder presents the 2108, the next generation phono preamplifier built upon the fundamentals of the past while making meaningful strides forward in technology and design. Countless changes have been made to insure that the 2108 significantly improves upon the 2008 in every way.

Why? Because the best phono stage in the world is the one that makes you focus on the music instead of the electronics. The very things that make analog playback so special are the things that the 2108 passes along without alteration. Dynamics are quick and powerful. Bass is taut and solid. Images are distinct. Silence is just that. Nothing should be added, nothing should be subtracted. Music shouldn’t just play, it should transport you to another place. It should thrill.

And with the 2108, it does.
