Mark Levinson No51 Media CD Player. Very few of these made. Although this will not play SACD, very few CD Players can outperform this unit on 16 Bit CDs in todays market. People that buy CD Players that play all formats today cannot get the performance that this unit gives. These muscle CD Players are no longer being made and soon to be collectors items. This comes with all original carton, remote, owners manual. Condition of this is like new.
