2 amps for 5.1 setup

[admin_exported]

is it possible to have my pioneer vsx520 driving the front and centre channels and my old pre hdmi sony str db830qs driving the rear channels how would i go about setting this up and would i hear any noticable improvements in sound?

cheers d

i've just looked up on the spec on your pioneer amp it says it has a 5.1 output so why do you need to hook it up to your sony

If your Pioneer has pre-outs and your sony has the capability to bypass the preamp then you could hook them up. But as the previous poster said, why do you want to do that?

i just heard somewhere that adding a second amp for back channels can add to the front sound stage of the other amp is this not true???
