Does the NAD C541 have a IEC power cord socket? If you are using the stock cord that came with the player, try something like a Blue Circle BC61 power cord ($83 shipped), before you spend more on another CD player.
This is a no brainer, because you will want a better power cord, even if you end up getting a CD player in the end.
A better cord for the amplifier would not hurt either.
I say all this because your system looks well balanced. While you will notice an improvement from a better CD player, you would probably also need a better amplifier to fully take advantage of the upgrade.
Try something simple before getting on the never ending upgrade roller coaster.
