For something more unusual you could try the Swedish DA909 from Harmony Design. I have an early version of the smaller dac and really liked it. The new version is about $2000 and made with modules that makes it possible to upgrade later.

I couldn't find the product page in English but the Swedish page is here. You'll have to use Google translate or similar.
