Benchmark or Antelope?

Looking at these two (2) DACs and asking for some opinions from the student body. Will be used in a "Mac" environment. As an aside, I've heard really good things about Mytek, but it looks like "drivers" need to be fiddled with and that is a turn-off for me. I'm at the 1500 dollar (new)
price point and the referenced units come in around that figure.
