What is the best integrated tube amp under $3k ?

I have recently been bitten by the tube bug. For the most part, I really love it. My short experience with tubes is turning out to be filled with much analyzing and upgrading of tubes, cables and different dacs. I am also discovering the strengths and weaknesses of some of the components that I am using.
I am starting to look at replacing my Jadis Orchestra Reference and would like to hear from what other folks are using as their integrated tube amps. My plan would be to try to spend about $3000 for a good preowned amp.
I'd especially like to hear from anyone that has owned a JOR and has found something that they are satisfied with.
I'd like find something that will be able to drive Dali Helicon 800 which are about 90.5 db sensitive.
I have heard of SET tube amps that people seem very excited about. I would like to hear some objective observations about these systems as well.
Thanks in advance.
