When it comes in, I'll demo it in the store with my Apple TV (optical only), which will be my main use. They have a laptop with lossless files, so I'm pretty sure I'll demo it with that too. Once I get it home, I'll throw everything at it.
I looked at CEDIA's website, and it takes place at the end of September. I'd rather get my hands on one sooner, but I guess patience is a virtue. I've been waiting forever for a Rega DAC, but I doubt that'll happen anytime soon, regardless of what people tell me.
