№ 523
The Mark Levinson № 523 is the definitive preamplifier for the analog music lover. Six line-level analog and phono inputs travel through the Mark Levinson proprietary Pure Path discrete, direct-coupled, fully balanced, dual-monaural signal path for breathtaking purity and performance. With precision control including a discrete, balanced R-2R Ladder volume control, class-A Pure Phono stage, and class-A Main Drive Headphone output, the № 523 preamplifier delivers an uncompromising performance regardless of analog source. Housed in a 6000-series aluminum chassis, like all Mark Levinson equipment, the № 523 is designed and handcrafted in the USA.
The № 523 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 integrated into the front panel metalwork – a first for Mark Levinson.
The Main Drive Headphone amplifier circuit drives up to 32-ohm headphones in class A by employing the main output circuit rather than a secondary signal path: a perfect example of reducing clutter in the circuit design.
A selectable fourth-order, 80 Hz high-pass filter enables seamless integration of a single or dual subwoofers for full-range performance with a wide range of loudspeaker setups.
System-integration connectivity includes Ethernet/IP control, RS-232, USB for monitoring and configuration via web page, plus 12V triggers and an IR input. An included machined metal remote delivers the robust feel and precise control befitting of a component of the preamplifier’s caliber.
Designed and Handcrafted in the USA
Like all Mark Levinson equipment, the № 523 is proudly designed and handcrafted in the USA. A dedicated Engineering Center of Excellence in Shelton, CT houses Mark Levinson engineering and product development, just a state away from small-batch production at Mack Technologies in Westford, MA by a team of craftsmen who bring all Mark Levinson equipment to life.
