Hi, this is my first post!
I would like to buy a good portable source for my AKG K450 (from jingpinstore in China - ebay; probabily fake but sounds good for me).
Has someone tested the K450 with Hifiman HM-601 express?
Is the hiss/hum audible?
 
Thank you.

P.s. I'm using a Nokia Asha 302 phone, so I think the Hifiman will be a great upgrade...
