I second Duke. What he says is not nuts at all!
You can find many fine integrated amps for $600 that sound very much like many a $6000 amp (only lacking power or some features).....but you will generally find a marked improvement in speakers up to around $4000. Above $4000 speakers start to become a diminishing return (mainly improvements in dynamics, SPL handling and bass extension.)
