Overview

Based on Mark Levinson's proprietary Pure Path discrete design, the 526 model is direct-coupled, fully balanced  dual-monaural signal path device that provides outstanding clarity and realism.

Within a discrete, balanced R-2R Ladder volume control, a string of resistors, all with identical resistance (R), form the side of the ladder, with another set of resistors forming the rungs, all identically with double the resistance (2R). This unique circuit takes whatever current appears at its input and successively divides it in half at each “rung” of the ladder. Different combinations of “rung” currents can then be selected and added together, precisely delivering nearly any output current, and thereby, volume setting. Analog switches “steer” the currents.

The Class-A "Pure Phono" stage is discrete design, free of op-amps. The Pure Phono stage operates exclusively in class A throughout, employing tantalum nitride thin-film resistors polypropylene capacitors. The Pure Phono stage also contains physically separated channels and balanced inputs for purity. The Pure Phono stage offers a fixed-gain MM section with five capacitive cartridge-loading settings and an MC section with three gain settings and 10 resistive cartridge-loading settings. An infrasonic filter is included to manage rumble and warping.

Housed in a 6000-series aluminum chassis, made from aircraft-grade 6063-T5 extruded aluminum, the 526 is designed and handcrafted in the USA. 

The converter chip in the Mark Levinson Precision Link DAC comes from ESS Technologies, with five independent power supplies operating the converter chip alone, and individual linear power supplies for the left and right channels that power the discrete I/V and antialiasing filter circuits. 

526 offers five line-level analog inputs: two balanced (XLR), three single-ended (RCA), in addition to the Pure Phono (RCA with grounding pin) input. The preamplifier delivers its signal to balanced (XLR) and single-ended (RCA) stereo outputs, as well as a 1/4-inch (6.3mm) Main Drive Headphone output accessible via the front panel. The Main Drive Headphone amplifier circuit drives up to 32-ohm headphones in class A.
