Power amps for King II speakers

Please share your thoughts on good power or integrated amplification ($10-$30k) for the King Sound King II loudspeakers.

I have a 14'x17'x9' listening room and sit about 8' from the speakers.

Orchestra and chamber music are the primary listening genre.

In the past, my system has been lean and too forward, so I would like a more life-like (but not too relaxed) sound that captures the dynamics, transients and tonality of live music.

Thanks.
