[quote user="kiddo"]Surely the manufacturers could design surround sound amps that automatically set themselves up at the touch of a button.[/quote]
They do, lots of them. You just plug in the microphone provided, push a button, and leave the receiver to do its thang. Within a couple of minutes, or at worst ten, you have speaker levels, distances, and equalisation settings in place, ready for listening. If you've connected up the speakers incorrectly, it'll even tell you where you've gone wrong.
And it needn't cost you a fortune - Onkyo's TX-SR505 does all this for just £250, and Sony's new STR-DG510 for well under £200.
