Why toroidal transformer is supposedly the best type of transformer?

What is the scientific evidence behind this common claim?

I left a reply in Jason's thread by mistake, but a good explanation can be found here.

The primary advantages are size, low magnetic field and low acoustic noise. The biggest negative factor is cost vs power capacity.

The scientific evidence is easily measured.

Thanks stled and pinnahertz

Basic toroidal transformer advantages. Lower stray magnetic field. so less likely to induce AC hum into nearby components. Less tendency to have mechanical buzz or hum. Generally somewhat greater efficiency due to reduced core losses.

These differences have been somewhat reduced by better materials and construction techniques.

This is the kind of info I was looking for, thank you.
