I'm currently running the H11 rebased 85211 philips bulbs (4300k) from Xenon Depot. I removed the kit from our previous vehicle and recently installed it in our Yukon. I know it's not 100% oem, but it's considerably better and looks about as OEM as it gets. I am considering going with a retrofit setup using oem ballast and reworked headlights to accept a D2S bulb like the denali, but I honestly don't think there's much room for improvement compared to what I currently have and it's espically not worth the hassle and additional cost for what would be gained. You will not be disappointed with the XD setup with philips 4300k bulbs.
Before re installing the XD kit, I quickly tried a set of LED and they looked good but, IMO, the output on road doesn't compare to the HID setup (with 85211 bulbs.)
Here is a link to another user (Prormk) that installed a similar setup...he used oem ballasts from Retrofitsource with XD re-based philips bulbs rather than XD's full kit.
