S. Andrea said: Driving the HD 800s with the HeadRoom Balanced Ultra Desktop Amplifier propels them to still greater heights of resolution and depths of bass power and articulation. If you’re in the market for an absolutely top-quality headphone listening experience, you need to audition this system. Maybe as the HeadRoom folks say, “It will leave you grinning from ear to ear.”
