Hi yiari, welcome to Agoraquest. If you want Dolby-Digital Surround, you'll have to get an outboard digital processor that can function as a pre or a newer receiver that has both DD surround and pre-amp outs so you can keep using your TA-N90ES. If you're just using your 'S7700 for it's audio capabilities, it becomes much simpler.
