I replaced the cord on my Njoe Tjoeb 4000 (Marantz 4000) by wrapping the power cord with foil and shrink tubing and connecting directly to the block inside the unit. I don't know if it made a difference but it is more elegant.
Power Cord CDP Termination
Am considering a power cord upgrade to a Marantz CDP, but it has no plug on the back of the machine, IEC or otherwise. The existing "lamp" cord is sent through a small hole with grommet in the chassis wall and terminated inside. It was obviously not configured to swap power cords. Suggestions on upgrade of power cord in such a circumstance? Unsolder connections inside and resolder new cord? Install IEC male connecter, but considering small chassis hole wouldn't that be difficult?
