Will said:The problem is, whilst you can run a pre out into most stereo amps, you're still left using the pre-amp section of the AV amp, which are almost always rubbish compared to a dedicated stereo pre-amp. So its never going to sound as good, pound for pound, as a dedicated stereo setup.
You connect up the stereo sources directly to the stereo amp, such as a CD player. Connect the surround sources up to the amp. You can then let each do what they're both good at. The only downside is having to select the source on the stereo amp and possibly having to adjust the volume.
