Essrand go for it - one component at a time. My philosophy is buy the piece you really want and upgrade when you can or you might even find you don't need to upgrade. A statement piece in your system might make upgrading other components unnecessary because you might be completely satisfied with your sound.
OTOH compromise and you may be on the upgrade train forever...a well worn path of disappointment for many.
