Not a Jadis owner (a little out of my reach ;-), but listened to Jadis pre and power amps for years at Brooks Berdan's shop. Brooks was (R.I.P.) a long-time Jadis dealer, and always had them in his main room's system, hooked up to Wilson and Vandersteen speakers. I do own an EAR 868L, an over-looked jem of a line-stage pre. Using the phono stage of an 868PL (from it's tape out jacks) is not a crazy idea, but the line stage is so nice it's a shame to squander it! How the 868L compares to the Jadis integrated I have no idea.
