I currently have a Harman Kardon AVR 235 and I am looking to upgrade to something more up to date. I like the HK but I am open to other brands as well. I am looking for 7.1 and I use it for about 75% movies/tv and 25% music. My fronts are Polk Monitor 60's, center CS10, surrounds are old HTIB Sony satellites that I am also looking to upgrade and a BIC PL-200 sub. My living room is 30x14 but is open to other rooms. Any suggestions or thoughts would be greatly appreciated.......Thanks!
