need balanced tube preamp used

Hey guys, I used to have Neo 500 and was not too happy with them, I used them through McIntosh MCD1100 sacd/  preamp  and obviously that was a big problem, now I have Manley 240's and Jadis DPL and I am very happy. I need replace Jadis because of the brum noise from my Tannoy Westminsters, I need balanced preamp, any sugestions? Jadis sounds great, maybee Jadis JPS8? Or perhaps McIntosh 2500? I like to spend up to $6000 for used. Any sugestion for some great preamp?
