The Audio One caps are the stock caps in that pre. When Cary upgrades the caps in that pre they use the Jenson so you already have the upgraded caps for that preamp. They only upgrade the .22uF by the way.
As for personal taste I have found that the Auricaps are a good match in Cary gear. I had them installed in my CAD-211 monoblocks at the time of purchase.
If you really want to play around try changing the tubes in that preamp. Many swear by Sylvania in the front sockets and Raytheon in the rear sockets. I have also had good luck with National Union grey glass in the front sockets. I think that you can improve the sound of this pre more by messing with the tubes at this point than by changing the caps.
