Mark Levinson No 52 Reference Dual-Monaural Preamplifier














$25000

The No 52 is quite simply the finest Mark Levinson preamplifier ever. It is an all-analog, true dual-monaural design with a two-chassis configuration that separates the critical analog audio circuitry from the control section to maintain the purest signal paths possible.

The No 52 provides a comprehensive complement of inputs including three balanced XLR and four unbalanced RCA line-level inputs, and a dedicated phono input that is selectable for moving coil (MC) or moving magnet (MM) operation. Two sets of XLR and RCA stereo preamplifier outputs are provided, along with an auxiliary pair of XLR and RCA outputs that can be configured for fixed or variable level output with independent source selection. This enables the auxiliary outputs to function either as a third preamp out, a pass-through full-range subwoofer output or a record output.

The No 52 offers a unity gain SSP (surround sound processor) output that provides the ability to integrate the audio sources that are connected to it into a home theater system, while maintaining optimal and independent stereo operation for music sources. The No 52 provides extensive control and system interface connectivity via Ethernet, Mark Levinson’s proprietary ML Net, 12V trigger and IR control ports. In addition, a USB 2.0 (A) port facilitates possible future software upgrades. The No 52 is supplied with a remote control that can also be used to operate other Mark Levinson components.

The Mark Levinson No 52 is built to an extraordinary level of refinement. Its control section features mirror-imaged DC power supplies and AC regeneration circuits for remarkably clean and stable power delivery and signal purity. Individual left and right DC umbilical cords are used to connect to the audio sections in the second chassis, and control signals are delivered via a third cable to keep them isolated. The audio chassis is laid out in a mirror image, left/right configuration with isolated and independent circuit boards for the volume, main and auxiliary signal paths, and extensive shielding for critical components. The chassis is constructed from heavy aluminum extrusions and plates.

Like all Mark Levinson 40th Anniversary components, the No 52 is striking and elegant in appearance, with a rich, brushed metal black and silver faceplate accented by red illumination against a glass center panel.
