Can any Pioneer VSX-C402/ 502 amplifier owners report back on their equipment. I am much more drawn towards slim line digital AV amps, than the typical enormous AV amps that weigh in around 30kg. Are there are drawbacks to the slimmer amps or is there surround output as good as you could have hoped for? Also if there are owners of other brands of slim line digital amps could they report back too. Lastly, when is the PhilipsDFS9000 digital amp finally going to be released?
