Best integrated amps under $9k

I am building a new house and I will be having a large great room ( 25x28).  I love music and and I love to hear all the different instruments clearly.  I don't need a heavy bass.  I am also not going to be playing music at real loud levels.   I like wide dispersion speakers.  I have been looking at integrated amps from Krell, Classe, Pass, Macintosh, ATI.  Any advice?  Sound quality is really important to me.   Whatever I buy will last a lifetime.  The reason I am thinking about integrated is that I like the idea of AMP/Pre-Amp in one box.  Any input is appreciated.
