OP, I recommend a Marantz AV60 or AV50 receiver. Start with a pair of speakers and a sub and add more channels if you like. I think a 5.1 setup is a minimum for enjoying movies. The marantz is great for music too.
I have a state of the art 9.2.8 system using a Marantz processor for movies and atmos music. I have a sony signature DAC that I use connected to the marantz for 2 channel. I have tried 3 separate dedicated two channel preamps in this system thinking it would be better than the marantz processor for stereo. Did not add anything, the Marantz is very, very good as a 2 channel preamp as well as multi-channel.
