Would add that many options for $7500. How much it actually costs will mostly depend on features and power requirements. If no brainer means going as loud and clear as you want with any speaker, for me that means 200w/ch or more. If you can live with spls that are not damaging to the ears (under 90db) then good sound with most any speaker can be had for much less.
Of course with high end audio, the sky is the limit in regards to how much it can cost but at some point you are paying mainly for build quality and/or aesthetics and the sonic benefits become more marginal and debatable as well unless you have heard the product before and had a chance to compare to others.
Then there are good quality high power tube amps which tend to be very expensive and lots of tubes to deal with and maintain .... Also inefficient and produce lots of heat.
