Large Surround System

Hello

I am trying to build a surround system for home theater.

I bought 6x250W RMS amps from RSE(lectronics) and have put them into two boxes (because they are so heavy you can't fit them into one box!).  I have built speakers and tested the system.  It is pretty powerful.

I want to do some DSP stuff so I have ordered samples of the Analog Devices AD1871 ADCs and the AD1852 DACs.  I am going to use the dsPIC30F6012A as the DSP.

I am having troubles with noise from the DVD player :evil:.

I was wondering if the signal processing will be enough to remove the noise and whether I should put any surrounding circuitry?

Also are these ADCs and DACs any good?

Thanks

Pete
