About the No 32

The Mark Levinson No 32 Reference Preamplifier is a revolutionary high-end audio component and the first Mark Levinson preamplifier to carry the 'Reference' label, signifying its status as the company's most advanced preamplifier. It features a dual-chassis design separating the power supply, control circuitry, and display (Reference Controller) from the sensitive audio preamplifier circuits (Reference Preamplifier) to minimize noise and interference. The power supply uses a 400Hz oscillator-generated AC source for cleaner, more efficient power delivery compared to standard 50/60Hz mains. The preamplifier chassis is built with a die-cast aluminum wall physically and electrically isolating left and right channels, achieving exceptional channel separation and vivid three-dimensional sound imaging. It offers eight configurable stereo inputs (3 balanced XLR, 5 unbalanced RCA), with unbalanced inputs converted to balanced signals internally. Outputs include four main stereo outputs (2 balanced, 2 unbalanced) and three record outputs. The unit supports mono or stereo playback, selectable output polarity, balance control, and an optional phono module with highly configurable loading for perfect cartridge matching. The volume control uses a discrete attenuator with 66 surface-mounted resistors per channel, providing 0.1 dB increments. The No 32 is known for its extremely high build quality, advanced circuit boards made from Arlon 25N material, and meticulous engineering to ensure ultra-low distortion and noise. It is a two-piece design connected by high-quality umbilical cables and weighs approximately 71 lbs unpackaged. The preamplifier is highly regarded for its intimate, natural, and detailed sound quality, making it a top choice for audiophiles and professionals seeking the best possible preamplifier performance.
