My advice is something with Tubes. A 30 w/c tube amp is plenty for the Sttafs.
I'm on my second pair of Sttafs. The first pair I sold ~2 years ago when I upgraded to Mani-2s. I recently bought another pair for a small room system I set up. I'm driving them now with my TAD 60 tube amp. This is the best combination I've had with the Sttafs. I have driven them with many other solid state amps (no integrates though), and frankly they sound great with everything I tried. Other than the tube amps, the best was B&K M200s.
