    № 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.
