Anm, Yes, a more descriptive title would help. But the lack of response,( i mean 73 views)I guess,is because the yulong d100 is pretty much an unknown commodity here in our forum.
From what I have followed on head fi and comp audiophile, the d100 II seems to do asynchronous usb, uses the ad 1955 dac and has positive reviews on the sound signature, with remarks like "detailed", "textured with body to the sound" etc.
However, in the head fi yulong d100 thread, I have also noticed many complaints regarding reliability issues.
The Yulong Sabre D18 seems to be the focus of attention of audiophiles, from the Yulong range, but its about 250$ more expensive.
