Originally purchased a few years back when I did research on the most reviewed Discman ever made: Akai PD-X73 (aka Optimus CD-3400, Grundig CDP100). PD-X52 seems to be Akai own design, with mostly Sony chips, Sanyo LC7883 DAC and SF-92.5 laser
Plays Scratch-Test CD and CD-R packed with 80+min of tunes without any problems! Please consider photos as part of description, ask questions BEFORE placing a bid
