Hey everyone! I'm having a dilemma here on which receiver to choose. I have been following the thread titled "Sony STR-DA4ES and DA7ES have arrived" and a lot of you are saying that the 4es might be inferior to the 5es? If this is true I'd like to get my hands on the 5es pretty quick because everyone is about to be out of stock on them. I understand the 4es has a 7th channel of amplification, 12 volt trigger, composite to s-video up converter and 1 remote instead of 2. Is that about all of the new features the 4es has over the 5? What exactly does the up convert and 12 volt trigger do? I would just like your opinions on which one you would get and why because the 5es, even though it's discontinued still costs about $100 more than the 4es and I'd hate to buy the 5es if the 4es is in fact the same but with a little more features for a lower price. Thank you for your input!
