korkster,

I know EXACTLY where you are coming from, when you said: "subtle differences" regarding the sound quality.
I believe you heard, what you heard........but all that, the sales guys said about "properly warming up", and "playing a cd for 3-4 days.....before listening" makes no sense. Your new cd player may sound better....but that's not why.
Enjoy.
