Do all toroidal transformers hum?


Help Gurus,

When I put my ear (about 2 inches from the top)to my integrated amplifier, I can hear a faint hum from both the transformers. Can't hear anything when I move my ear away from the amp. Is this normal?

I had significant hum problems with my Karan K180 amp. Much to my suprise, changing the power cable made a big difference, not sure why, might be worth a try.
