Guys, your opinions on Yamaha RX-V675 and Denon AVR-1713? They're similarly priced in the used market. The Yamaha has YPAO RSC and the Denon has Audyssey MultEQ XT. As far as I know the YPAO RSC only handles frequencies down to 31hz, which MultEQ XT goes down to 10hz.
My sub has a -3db point at 20hz, will I need the MultEQ XT for it or is the YPAO RSC good enough?
