I use a 518 between my G68 and my Squeezebox and it makes a BIG difference. I have it in bypass mode so the difference must be due to lower jitter vs adding more dithering. I agree that there is still a lot of jitter in all but a very few digital interfaces and none are free from the problem.

When I compared the SB3->518 vs my G98 spinner into my G68 the G98 sounded much better than the SB3 until I added the 518 at which point the difference was very slight.

... no sig here ...
