Personally, I would keep the JOR. So far, I've not found anything that eclipses a Jadis, though I want to try an Audio Note.
I recently got my DA30 up on its feet, after spending a couple of years on the shelf gathering dust while I used my DA60 instead. My friend, Jeff Carder, owner of CarderSound speakers, was over my home a couple of times and listened to the DA30 in my system. He commented that it's one of the best amplifiers he's ever heard, and just HAS to have it. I can't say that anything about it jumps out, but we both feel that it just plain sounds more natural than anything else we know.
