The Aorz I ordered and tested, then got others to try, seems the best readily-available and in-stock HDMI DAC out there. It's capable of between 270mhz - 295mhz, with a sample size of about 4 or 5, allowing up to 1920x1200i@160hz.

The fabled 360mhz IO Crest is the random one that went out of stock and no one can find it anywhere now. I'd say the Aorz is a pretty safe bet to tell people about more generally for a decent HDMI DAC
