Hi
Mark is correct,I know its not what you want to hear but you are looking at receivers that totaly outclass your speaker system If you plan on upgrading your speaker system later on then out of the two I would choose the Yamaha
its YPAO has been corrected and is fairly accurate and its pre-amp out puts are very quite This is very uncommon for receivers this receiver will serve very well as a stand alone pre-amp
Good Luck
