Amp / preamp for macintosh xt50


Hello guys ..
I recently buy the xr50 speakers  // small room .
What is your recommendation for amp &  pre ? 
Budget under 4k

In that price range, a McIntosh Integrated would be perfect.  You won’t get much in separates for $3-4K, especially if you want McIntosh. 
@stereo5   thank you ..
I do not want mcintosh gears .. what else brands might work good with the XR 50 ?
