Question toroidal transformers

I have a 200W per cahnell amplifier that had a 800VA toroidal transformer.Is there a difference if i used a normal one instead the toroid?

thanks!
All the best

Larger amount of EMIs interfering with the signal.

Not if you keep the transformer away from the preamp.
The benefit is the startcurrent. When using a toroid transformer over 500VA you CAN have problem with the start. Sometimes you can use a relay in the primary winding...... not so with a normal transformer.
The negative is the electrical field as nbcd said. Risk of influence from the transformer. (But not if you keep it away from the preamp)

cheers
