The main advantage to toroidial transformers is that more of the magnetic flux
generated by transformer operation is kept inside the core than in a
conventional design.  This means that the flux is kept away from nearby
signal leads where it could induce 60 (or 50 as the case may be) Hz hum
into audio circuits.
The main disadvantage to the torodial design is that it is more expensive, due
to higher manufacturing costs.
