You'll be better off considering how you enjoy your set up most, rather than automatically running off and buying the AVR du jour.
*IF* you care more about sound quality than the number of channels or WPC ratings, you should follow the cardinal rule of purchasing speakers that make you fall in love with them, THEN get equipment that bring the most out of them. It is indeed possible to get audiophile quality sound from some home theater equipment today.
