There aren't too many options, but there is one lesser known DAC that has DSD capability:
http://sonore.us/index2.html - Sonore DSD Dac
It's cheaper somewhat, but lacks many features.
Don't mean to pollute your thread but if I may add a few more to the list.
ExaSound Audio Design E20 DAC was just announced recently, it's pricier than the Mytek though :-
Another is the Chord QuteHD DAC but it's a DAC-only separate amp required, and a much more expensive model QBD76 HDSD :-
