Modifications to California Audio Labs/CAL Delta?

Does anyone have any experinece upgrading their California Audio Labs Delta transport? I have seen lots of ideas out there for upgrades to other players, but haven't seen any DIY mods for a Delta. I don't have any problems with it, I just like to tinker and anything that will help make it even better would be great. For full disclosure the Delta is hooked up to a Genesis Digital Lens and then to a Tube Audio Design TADAC for D/A and preamplification via Cardas Neutral Reference digital ICs. Any insights or ideas greatly appreciated! Thanks in advance.
