X-fis quite good and the front panel has a direct headphone output and I hear its amp powered.
Sorta odd but it still provides a cleaner/powerful better SQ signal compared to my hi-fi amps even so ive ended up using it directly from there.
Maybe wiser to get the full x-fi one apparantly that has even better SQ, although dunno how much by.
Hd595s are lovely very well balanaced and are good from a X-fi output
