Zero hum here.  Fantastic amp... and the Sophia Princess is a match made in heaven, unless you have brighter cans like the K701, then the Sophia Princess sounds too strident.   This is the ONE product that I have bought on Head-fi that is 100% perfect for my needs and I haven't thought about upgrading for one instant.  I wish I could say the same about headphones.  I use mine for minimum 4 hrs a day, usually 8-12 hrs a day in my art studio.

. with 4 RCA inputs, i can use it as a selector for my CD, SACD player and the Radio.
 
However, mine have heat generation problem, maybe my place is somehow does not have airflow at all.

On my WA6SE, after 8 hours of listening, the only thing that gets above room temperature are the tubes themselves.  No heat issues at all.
