Fred, thanks again.
All of this make a little more sens to me now.
Are most of the people able to hear the flatness of a speaker (+-3db vs +- 5db)? I am just wondering because I think I wouldn't be able to tell the difference. Maybe my hearing is not that accurate
As for the receiver, the Denon 3808CI seems really nice but a little bit pricey for me? It seems that most of the Denon and Yamaha in the $700 price range don't support 4 ohms impedance. How come this is not popular?
Anyway, thanks everybody for your input, this is a great community
