Like what was mentioned before. Run the calibration setup for the receiver. Test the sound with different audio media sources (TV, DVD/BLRY,Music..etc). If the sound is to your liking, then leave everything as the calibration set it. If not then go into the Sony menu and start making small adjustments, like crossover freq setting and a good place to start is about 80Hz and increase to the next setting until you get the right bass to treble response from your speakers and Sub that you like.
Next check out individual speaker level adjustments or volume output levels and different sound and surround sound fields for what works best with your room environment.
Also remember that speaker placement is critical to achieving optimal sound quality from whatever type of AVR you own.
And for WiWave, why don't you go out and spend your money and buy Adam the kind of AVR you would like him to have because none of your input here was of any use in helping addressing the question asked.
