Rega vs Burson Dac

I've recently been listening to the Burson 160D headphone amp and dac. I'm amazed at it's price performance ratio, and while it's a great headphone amp, the dac is also very impressive. Has anyone heard both the Burson and the new Rega dac? A trusted friend believes the Rega is the best in it's price range, and while I have no doubt that it's good, I'd be curious to get comments from someone who has actually compared it with the Burson.
