Default I made the usb based high-end dac

I made the usb-based high-end dac.
It accept audio signal from PC through USB. PCM1798 is used to convert and AD827 is for I/V Converter and OPA627.
It is also used heaphone amp and has the digital out.
So powerful! What do you feel about this?
I'd like to listen to all opinions.^^

Your description omits the most important part: how do you convert the usb input to a format acceptable by the DAC?

No matter how good is the dac chip and analogue part you might have a real bottleneck here.
