Hello,
 
I'm thinking about picking up a W1000X and AD2000 over the next few months and was wondering if there is an amp that would work nicely with both? They're both low impedance cans (40-42ohms), and I don't want to spend any more than $300 - so was thinking about the Matrix M Stage or Schiit Asgard.
 
This will be my first amp, so I'm a newbie here.
 
Thanks for any help.
 
edit: oh and if there is a portable amp that fits my budget and will get the job done, let me know!
