I have mission speakers (front m35, centre m3c2, back m32 and rear back m32).I am thinking to buy new receiver and the first idea is denon avr-3805(I know that mission and denon are quite compatible).But I am thinking are my speakers worth to buy receiver which is higher price range than them? And also if that is uneconomic would change my rears and r.back m32 with m34 (I have that option from my dealer) difference and use bigger potential of denon receiver. Thanks.
