And it seems that you've got it, though to the extent that another of your components can't deal with it, and I still suspect it is the speakers. Whether it is or not, I would suggest you go back to the dealer with whom you have spent a rather large sum of money, tell them your problem, and see what they'll do about it. And bearing in mind how much you've already spent, if they're not willing to lend you other CD players (and, I'd suggest, speakers, so you can isolate the problem) to audition at length in your own home until you're happy, I'd suggest you find another dealer.
