Thanks for the hep Mac.
The room is about 20'x20' with 10' ceilings, but opens up to the kitchen, which adds another 20' or so to the length. This is the family room and I'm afraid the wife isn't going to go for speakers on stands, so they will either be on a bookshelf or some flat surface near a wall. I can probably give them 10" for the wall to the back ports (assuming ported). Should I be thinking in-wall if this is my set-up?
I have and old Sony STR-DE545 pushing them now, but plan to solicit advice on the receivers forum as to what I should replace that with. All my music is in iTunes, so would like AirPlay built in to the Receiver. Seems like Denon makes some models with this option. I'll budget maybe $300-$400 for that receiver.
