I have tried that exact combo. The result is quite nice, imo. But it really depends on your view of the HD800 - do you find it extremely bright? If so, you will want the smoothest DAC and amp chain possible. Do you find it perfect as is? If so, you'll want a mostly neutral DAC and amp.
Personally I don't think the V200 is all that colored. It's just got some minor character to it, kind of like the X-Sabre. So it works for me. But I tend to prefer smoothness to extreme detail/clarity, most of the time anyway.
Are they mutually exclusive?
