description

Very good condition, we sold new.  All cables and remote included.  Ships in original factory wood crate.  Unit must ship freight due to size/weight.

The Nº52 is unquestionably the finest Mark Levinson preamplifier ever. This dual-monaural preamplifier isolates the critical analog audio circuitry from the control section with a two-chassis approach to provide the purest signal paths possible.

Nº52 Highlights

  • Two-piece chassis with separate control box and analog box
  • Dual Monaural construction and signal paths/routing
  • AC regeneration circuitry
  • 7 Analog inputs: 3 XLR and 4 RCA stereo input pairs
  • Phono input with support for both MM and MC cartridges
  • Rear-panel USB (A) connector for software updates
