Portable amp for iPod classic and optical Xbox?

Hi, I have been looking for an amp to go with my IE8's and iPod classic was going to go for a Protector, I have just bought some. HD600's from a member here and intend to use them for Xbox duties, my question is can I buy one decent amp for both, I am aware of the Astro mixamp but this is no good for portable duties, anything from iBasso, RSA suitable for both with an optical in for the xbox?

Thanks for your time.

iBasso D10 looks like it could be the answer? I know I won't get full surround but it saves having 2 new devices .
