I need some help trying to set up a multizone home theater system. I have 5:1 in the main room of the home and I have 4 exterior speakers by the pool and cabana area. I've set this up before but with only 2 external speakers on the 2nd zone. It's been a while since I've set up a system but I have noticed that technologies have changed big time. I am upgrading my amp. Is the best way around this getting a receiver/amp that has three zones versus two, or is there another configuration that I can use keeping in mind budget. Thx!
