SET amp suggestions 1000$ or Integrated 2500$

Hi, I am thinking of changing directions, and flipping 180 degrees. I have decided to try out some efficient speakers and I'm a bit scared of having them hooked up to a 1000W McIntosh. I would love some suggestions for a SET or other low powered tube amp/ Integrated for the suggested prices above, so I can spend my next few sleepless nights reading and obsessing.
I currently have a Cary slp-98 and really like the sound although, I would be okay with selling it if I could get better performance from an integrated. I have also owned a sli-80 which I enjoyed, and is a consideration, but basically I know nothing about 5-22 watt tube amps, I have read about their strengths and weaknesses, but like most things in life you really have to try it yourself.

Thanks,
Mike
