While my laptop Asus N53v, plugged into the same wall socket as my tube amp, i get a SERIOUS amount of hum buzz and noise, when it's plugged into my wall down at the living room, almost dead silence.

 

Now the question is, will a isolation transformer help?

 

Like the

KECES PT-111 (VERY EXPENSIVE)

http://www.audiocircle.com/index.php?topic=62587.0

 

or like the Tripp Lite (more reasonable)

Since the tripp lite has two socket, I will plug my KECES DAC and the amp into it in the same time,

does it mean when my laptop is plugged into the other socket, there should be no noise by the laptop 

AC adapter?

 

Thank you.
