Sony X55-ES CD player... thoughts?

Is it an x555 es or just the x55. If it is an x555, i owned one for a long time. it dates to 1991, and was sony second from top of the line back then. very solid player and sounds pretty good. It does not compare to my Naim player but it was excellent value for money.

after thinking about it, this is the player i had. it was solid and sounded very good for the money. i think i paid 700 for it new back in 91. the transport started to go, so i gave it to a friend in colorado.
