About the No. 37

The Mark Levinson No37 CD Transport is designed to extract digital information from CDs and deliver it to a digital processor with minimal timing errors (jitter). It employs a proprietary closed-loop jitter-reduction system combined with a custom crystal oscillator of better than five parts-per-million accuracy. This oscillator reclocks the digital signal immediately before output and controls the all-digital servo that manages the disc spinning rate, effectively eliminating transport-related jitter. The design places the reference clock at the final output stage, slaving mechanical subassemblies to it, resulting in a signal uncontaminated by electrical or mechanical jitter. The transport features a hand-brushed black-anodized aluminum faceplate, bead-blasted custom-machined buttons, and a slim aluminum loading drawer riding on polished bearings. It supports multiple digital outputs including balanced AES/EBU (XLR), single-ended S/PDIF (BNC and RCA), and ST optical output. The laser mechanism uses all digital servo controls for focus and tracking, ensuring stability and precision over time. Additional features include full programmability, a large display, remote control, and a sophisticated inter-component communications bus for system integration. The No37 is praised for its clarity, warmth, and dynamic contrast, making it a highly regarded digital disc playback system.
