This is the new 585.5 with Pure Path Class A phono stage, new case work and more. Please see the Levinson website for technical details. There are no other 585.5's out there on the preowned market that I could find. These are made to order and are not the same unit as the 585. All accessories and and boxes included . 10/10 condition. Selling to build an all tube system so this jewel must go. This is a great integrated with the best solid state phono amp I have heard in a all in one chassis. These are $16K new, I purchased new from authorized dealer in Denver Colorado.
