Ok Darren, first things first, as far as separates vs integrated and receivers go, is that the amplification and the processor share the same chassis vs a separate amp having more room for bigger internal parts and amplification for more power.I have read in this forum that yamaha is not a good match for klipsch,personally I prefer denon their highend receiver offer 170x7,Sunfire ultimate receiver offers 200x7.When talking amps B&K gets alot of prasis in this forum, rotel,parasound,adcom,are also very good,power range between 125to200 watts per channel.If you take this route you will need a processor remember price was not a limitation.Good luck
