Boulder 2108 Phono Preamplifier

The 2108 is Boulder's flagship phono preamplifier, built as the successor to the 2008, with the goal Boulder states as letting listeners focus on the music rather than the electronics.

It is a fully balanced design with a separate power supply chassis housing four independent supplies, built around Boulder's proprietary modular 995S phono gain stage, hand-manufactured and calibrated in a potted, precision-machined housing.

Each of its three balanced inputs accepts swappable Personality Cards for cartridge-specific MM or MC loading, gain, and demagnetizing.
