A systems musical potential can only be fully realized with the assistance of a high-grade preamplifier. We have invested all our expertise into the development of the Corona Line preamplifier, holding it to MBL's high-end standard, unimpeded by any constraints, and created a control center adept with any kind of music, down to the very finest detail or each subtle change of mood or timing. To achieve this, we designed the Corona Line preamplifier around the best available potentiometers for acoustically perfect tracking and volume control. Our sophisticated power supply system would enhance any preamplifier. All subassemblies are carefully isolated to prevent interference that could diminish the music's nuances. MBL's uncompromising approach to development makes for superb quality and consummate musical enjoyment.
