Starting from zero, I've done a lot of research but could really use your help to finally make the decisions. I want to start with a basic, simple system for 15x20 room. Music first, movies second. Don't care about 3D. Want streaming via wireless. Have Apple Airport. Already have Energy CB20 bookshelfs and Energy subwoofer. Are they enough for decent HT? Can spend up to $1,500 or so total. Looking at Yamaha v671 a/v receiver or Marantz equivalent so far. Would prefer one unit for CD/DVD. Is Oppo bhp 93 overkill? Is DAC important? Thanks for your expertise!
