Do you mind explaining how you got to that number? I'd love to be able to figure it out for myself in the future. Thanks

I'll second that.safer,
You can find the designers site easily on the net...and read about his and in the comments / blog there are several comments on dac comparisons.
I have compared with several, HRT MSii+ USB , ESS Sabre Dacs in a high end source, there is no real detectable differences to my ears with cans or speakers IMO.
This is a great dac and compares very well with many others priced much higher....
I am sure others will chime in..

What's the output power of O2? I'm thinking of getting it to replace the trusty E17 in driving my HE400s.
On battery, something like 534mW (4.2V) into 33 ohms, 338mW (5.2V) into 80 ohms. So for ~50 ohms HE-400, maybe something around 500mW (5V), definitely not shy of 350mW. That's the advantage of packing two 9V batteries.
But to reach that level without clipping the input, you need to be careful about getting the correct gain, given whatever source you're using. Then again, you really don't want to be pumping 500mW into HE-400 and having that placed on somebody's head.
