Which did you go with?  Any advice between GO 450 and C5D?

Thanks for the comments.   KT66, I have looked at that unit.  Pretty cool design.  Do you know how it stacks up to the others as far as performance?  Am I splitting hairs in this price range?

Hi!   I was wondering anyone could give me some advice on a portable DAC/amp selection.  There are plenty of good product reviews out there to help me, but in general there's many variables in the overall performance of a setup, and it's hard to find advice on my own particular equipment...
