Hi, new here to the forum, looks like there is lots to read up on. Anyways. I am looking to purchase a new receiver to replace my old JVC RX-550v. Have a buget around $600, would like to go a little less. Have been looking at the Marantz SR-6200,7200, or maybe a Yamaha RX-V800, or Denon AVR-982. Any opinions on these? Am I looking in the right direction? Will be used mostly for DVD's and some music. Will be pushing 2 Boston Acoustic A100 Series 3's and 2 Infinity unknowns. Looking for a center channel speaker too.
