I too festered over adding a digital source to my analog/vinyl front end.
(Dont take my bluntness as being arrogant, but... Get over it..)
The Xilica brings so much to the table for Jubilees, it would be almost foolish to try to go passive..
I would be very surprised to see a passive network sound better than a dialed in Jubilee setup with an active DSP.
TAD TD-4002.... To be honest, they are not worth the money at the current unobtainium costs they are going for... Plus its always a gamble if the BE diaphragms are in working order, if not your in it for even more money.
Instead, opt for the Faital HF20AT drivers or the Radian BE drivers.
The Faitals are now discontinued but you can still find them at a fraction of the price of the TAD and the Radian BE.
I am currently running the Faital HF20AT drivers with a First Watt J2 amp it would be very very hard to tell the difference between the TADs in a blind test.
My last suggestion would be trying to go all balanced if possible.
Jubilees are not for the faint of heart and while Cory and Roy do their best to get these things as close as possible to Plug and Play, it will take some serious time to dial them in for that last 10% of fidelity... It took me just over a year to get mine to where i would say they are perfect.
Good luck with your Jubilee journey, they will be the last speaker you will ever own.
