Ok, say I purchase a Adcom GFA-7605 Home Theater Power Amplifier how is this physically connected to my existing receiver? Then Im curious as to how volume is controlled? I would be running this power amp to all 5 of my existing speakers?

Thirdly, would this external amp improve music clarity and detail at lower volumes?
Receiver: Pioneer Elite VSX-43TX
DVD PLAYER: Sony DVP-NC655P
Mains: Bi-Amped Polk Rt1000i
Surrounds: Bi-Wired Polk Rt55i
Center: Bi-Wired Polk Cs400i
Subwooofer: SVS PB1

    rca cable from your receiver's preouts to the amp. receiver controls the volume after you use your spl meter and setup program to get everything all nice again :)
    i use an amp to just power my front 3s for now

    Those are inputs, your receiver shows only one pre out, for the sub.
    Take a look at the other sony's, they show in's and then there's the pre outs to use an external amp with.

    like the guys here said.. you must have preouts on your receiver to use an external amp like the Adcom you are looking at.

    Volume is controlled the way it is now. from your receivers volume control knob. none of that will change when you ad an external amp.

    Yes would need to make sure the external amp you buy is 5 channel amp. there are 2, 3, 4, 5, and 7 channel amps. The more channels. the more expensive.. and the more watts per channel too.

    External amps will usually add some clarity to your receiver when added.

    good luck dude, come back here if you have more ?'s
