Hey guys. I'm planning on getting both of these headphones and choose the one that I prefer the best, but I need a good capable amp that compliments the two well enough. 
At the moment I am looking to get a Schiit Valhalla: http://schiit.com/cart/index.php?main_page=product_info&cPath=0&products_id=2
 
Any places with good return policies are preferred as always! Thanks 

 
note: I will be using Titanium HD's Burr-Brown [size=small]PCM1794 DAC for now. [/size]

Budget range? Graham Slees is a good option for beyer but perhaps a bit too mellow/warm for senns

~$300 Nothing fancy really. Just anything that'll make them sound good.

HD650 and DT880/600 compliment each other well. If you are into DIY the Bottlehead Crack is a good match for both cans.

Crack is a good option for that price range
