Hi Haku, I'm doing review for Yulong DA8ii, the top of the Yulong stack. the other 2 are my old Yulong DA8 and Yulong A28. How do I like them? They all have different sound signature The old DA8 is smooth with a touch of warmness, IMHO, not very suitable for R70x. Yulong A28, the amp, is even warmer, definitely a no no for R70x. But the new DA8ii had departed from DA8 warm signature, more transparent and detailed, with better texture. I just recently listen to it, it sounds pretty good on R70x, but I will reserve my comments until I have enough time with it. You're most welcome! V200 is quite neutral, so it is pretty much depending on the DAC section. I find it pretty good for R70x, though my preference is lean more to the ifi stack for R70x.
