The No 585.5 is designed for beauty and performance inside and out. The steel and aluminum construction features Mark Levinson's iconic black and silver anodized aluminum front panel with their intuitive hourglass-shaped twin-knob control system and unique red display. A newly designed 3-piece anodized brushed aluminum top cover and custom aluminum feet, buttons, and remote control enhance the luxurious industrial design. Inside, fully discrete dual-monaural analog circuitry is meticulously arranged in a mirror- image design for symmetry and performance. All metalwork, even the internal hardware, uses cosmetic-grade metal.
