I have been recommended both of these receivers by my local dealer, but honestly i dont knwo alot about receivers, so please feel free to flood me with information. My main concerns with upgrading are well not having to upgrade for a while. to that end I am planning on gettign a receiver that can do DD EX and DTYS ES (discrete of course) plenty of inputs is a must, particularly regarding optical inputs and digital coax. my current receiver si a sony STRDE 445 which only has one optical input and one digital coax, and both are for the dvd source... uggggg. so i am hoping you can all flood me with info about what i should look for, i know the marantz dosent do component switching, and that is a downside for me, are there any decent options for component switching? my tv only has 2 inputs and i fear in a year or two i may need at least 3.
