About the Reference 5SE

The Audio Research Corporation Reference 5SE is a premium stereo tube preamplifier introduced in late 2011 as a successor to the Reference 5. It incorporates advancements from Audio Research's limited-edition Anniversary Reference preamplifier, including a redesigned front panel with round metal buttons and a significantly enhanced power supply with nearly double the energy storage capacitors. The Reference 5SE offers six sets of balanced and unbalanced inputs, including CD, tuner, video, phono, two auxiliary inputs, and a processor input that bypasses volume control for home theater integration. It provides three sets of balanced and unbalanced outputs, with a fully balanced signal path recommended by the manufacturer. The unit features a large front-panel display showing volume level, input selection, and status indicators, all controllable via a metal remote control. The Reference 5SE is known for its extremely low noise, wide frequency response, and very low distortion, delivering a highly musical and detailed sound signature. It weighs approximately 30.4 lbs and measures 19" W x 7" H x 15.5" D. The preamplifier requires a 600-hour break-in period for optimal sonic performance. It is considered a benchmark in high-end tube preamplification and can be upgraded from the original Reference 5 for a fee. The Reference 5SE has been succeeded by the Reference 6, indicating it is no longer in current production.
