Toroidal vs. Non-toroidal Transformers

I am an experienced audiophile, but am unsure as to how much weight should be given to the presence of a toridal transformer in a CD player. I am comparing the Marantz SA-15S2 to the Denon 100th Anniversary SACD player. With the cases open, the main difference I note is that the Marantz has a toroidal transformer, and the Denon does not. I am one who buys all of his gear on-line, sight unseen, and so design and parts quality are important to me (they would be important to me anyway).

I believe that design and parts quality have a direct relationship to performance. I am not one to readily accept the advice of: "Well, just listen to the players." I suppose that if I listen long enough, I might end up seeing the positive points of almost any piece of gear--and such is why I always marvel at the suggestions of "200" or "500" hours of "break-in". I would rather make an informed initial decision, as well-designed components with quality parts--and good weight and build--have rarely disappoined me. I welcome any relevant comments.
