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.

I don't think it matters much as to the type of power transformer used. I am sure there are "cheap" and "better" forms of either type, but, how would you be able to tell. Both kinds will do the job effectively.

There is a bit more of a tendency for toroidal power transformers to hum or buzz (the transformer itself vibrating and creating noise, not noise injected into the output signal) if there is crap on the powerline, but that hardly happens.

If the only obvious difference that you can see between the two, in terms of build quality, is the choice of power transformer, I would call it a tie.

I have no experience with the Denon SACD player. I've heard various Marantz players and they sounded pretty nice for the money.
