Your CD player is very old (20+ years) and really is it worth spending time and money trying to upgrading it? I highly doubt you'll hear much sound difference with a power cord change (I've been wrong before though).
I'd bet you'd have better sound quality results by spending the money that would be spend on a power cord on a DAC. there are some good DAC's that are under $250 that would sound a whole world better then the old one in the Nak. IMO
I'm not trying to be judgmental just bringing some (possible) reality to the discussion.
Also if you have never soldered before I'd get someone that has some experience to do the work, if you go ahead. bad solder joint on the power input could be a fire hazard. or get some training that could be fun also.
