I was considering the 4520 everywhere Ive looked all about MSRP. Is the 4520 that much better then the 4308? I honestly use the audessy mic to set everything up. But I disable all room eq to off. To my ears sounds more dynamic and powerful. What I currrently like bout the 4308 is I can adjust speaker trim levels on the fly..the 4520 does not correct? Have to go into the main menu..
what about the denon x4000?
I am only using the avrs amps for zone 2 &3
Will my dual svs sb13 ultras benefit alot from sub eq?
