decoders in AMP or in sound card ??? (1 Viewer)

respected savants,
Here`s my query:
Presuming we deal with a home theatre system of the followg form:
PC DVD + PC sound card > multy channel amplifier > active sub + speakers
In order to decode sound to any given format such as: DTS, or THX or any other for that matter,
should the decoders exist both in the PC sound card AND in the 5.1 amplifier simultaneously or would their integration in only ONE of the two elements be sufficient, and if so - in which is it better to have them - in the sound card or in the multy channel amplifier ?
Thanks wormly in advance ...

I'd venture the amplifier. you can connect the soundcard to the amplifier using the digital coax/optical whatever may be available. Chances are the amplifier has better decoders. Also, the receiver will perform bass management and channel trims on digitally passed content which may result in better sound overall. this generally does not happen on the 5.1 inputs as in the case if you did the decoding on the PC card
