[QUOTE="cmpx2_15_owner, post: 380769, member: 552218"] UPDATE!!!! I found out why the CD Player is tripping. After a careful look inside of the unit, I noticed that there is an IC (possibly the 24-Bit D/A converter) that is mounted upside down! This is part of the Nakamichi design but it is a POOR design. Reason being: heat goes up, and in this case....the heat generated by the IC gets trapped inside of itself (NEVER GOOD!)because IT IS UPSIDE DOWN!!! This problem is somewhat of a DESIGN FLAW, not necessarily a DEFECT. Nakamichi tried to cool this hot IC down by adding a heatsink plate to dissapate the heat, but an upside down heat generating IC with a heatplate mounted on it only helps out so much. There is NOTHING that Nakamichi can do about this problem, except to redesign the circuitry so that it is mounted right-side up.......I doubt that this will happen!!! So that answers whether or not I will spend $30+ for shipping to and from the manufacture just to have it returned to me 4-8 weeks later with a note stating that THERE IS NOTHING "WRONG" WITH THIS UNIT. However, there is an easier way that I can keep the hot IC cool: adding a cooling fan. Not one of those noisy and bulky computer case cooling fans, but one that fits snugly underneath the heatsink of the IC. I will try to post pics of this operation so that if other CD-400 owners experience this problem....they will have a place to look for answers. BTW, THE SOUND QUALITY DIFFERENCE BETWEEN MY OEM UNIT AND THIS CD-400 IS AMAZING!!! THE OEM JUST DOESN'T COMPARE. [/QUOTE]
