Hello everyone, I'm trying to help my mom find a Home Theater in-a-box System for my Dad for his birthday, which is tomorrow. So I am running out of time The only thing I know about HTS is what I have learned after two days of research on the Internet. I have narrowed it down to the following: Onkyo HT-S770 6.1 1000Watt $500 Yamaha YHT-450 6.1 700Watt $500 To me, the specs of the Onkyo appear to be better than the Yamaha, but I'm not sure which will actually sound better. I think the receivers are going to be similar in quality. I think the biggest difference will be in speaker quality. Which speakers will sound the best of these two systems? I think the Onkyo subwoofer will probably sound much better. Higher Watts and lower frequency. The Yamaha goes up to 200hz which might be too high for a sub? Or should I go with something much less expensive like the Sony HT-DDW660 5.1 420Watt at only $200. Even tho it is a lot less power maybe the speakers are much better sounding and will make up for the lack of power versus the other two choices? I know most of you have probably never listened to any of these systems, but based on your epxeriences and knowledge what is your best guess for the better system? Thanks to anyone who can help. PS: I would try listening to them but I am 2 hours away from the nearest city because I live in a remote area. Also, I would have posted links to the system specs but I am not allowed to until I have made 15 posts.
