AFAIK, the Jolida DAC hasn't been released. It's supposed to be out soon, but it isn't even listed on Jolida's website. Everyone who heard it at RMAF was impressed. You'll have to wait to get more info.
I haven't heard the HRT Streamer, but those who have say it's impressive. You should read the review in 6moons from Sept 2009:
