Wadia 170i iPod Dock Jitter

I have read the Wadia 170i Dock has a high level of Jitter at it's output. I am using a 1M Kimber D60 illuminations cable connected to my Cambridge Audio AZURE 840C and am not sure if the CDP re-clocks the digital inputs, the manual does not say. That being said, the new Wadia offering, the 171i claims to have lower jitter, but is the difference worth the expense of upgrading especially if my CDP may do a good job re-clocking? Does anyone have any experience or knowledge about this?
