Amp recommendation for KEF LS50


I’ve had the LS50’s for a while now and have been saving up for a new integrated to power them. Currently using Rotel ra-12 which sounds good but I was wondering if anyone had any recommendations in an amp that pairs well with the KEF’s. I have a budget around $2k and can stretch to $2,500 if need be. Not many dealers in my area so any help would be greatly appreciated! Also, room is roughly 12x15.  I have added room treatment to help as well.

If you are interested in maximizing performance you may want to consider selling your ls50s and getting into a pair of ls50 wireless. Darko did a test and had to go way up market when pairing electronics with the passive ls50 to get them to outperform the active. 
I second robr45. Having owned both the wireless is vastly superior in every regard.
PeachTree Nova 150 is great with the LS50's. Better than my old combo of Benchmark DAC2 with Parasound A23 amp. I think the Parasound was the weakest link. The Benchmark DAC is better than the DAC in the Nova 150. Overall the Peachtree package is perfect with the LS50's. I actually made money by selling my old gear and buying a used Nova 150.
 
Darko has a review on PeachTree with the LS50.
Job 250 mono amps will kill on the LS50. Add a low gain preamp,it's heavenly.
