Blazen69,
Before you dump the Cambridge, you may want to try what Philjolet suggests above. I have a Cambridge 640C which has the same DACs as the 740C, and it took MUCH LONGER than one month for the player to settle down. One suggestion would be to set the player on repeat night and day for about 30 days straight (whether or not it is driving the amp), and see if that changes the sound significantly. With that said, the Cambridge will never be "laid back" no matter how long it is played. But you might find that you do not have to choose between living with significant artifacts such as the shouty or harsh vocal peaks or getting another machine.
One last question: what kind of power cord are you using? A good or even decent power cord designed for digital gear may help preserve the detail Cambridge players are known for while softening some tendencies towards being overly forward.
