To be honest, my setup does sounds okay for movies, but I somehow feel the dialogue is a bit weak. This could be the common issue for two channel.
On the other hand, I had my Sony TV (current model with Dobby Atmos, hdmi2.1, eArc and a lot of other technical names) feeding Schiit Yggdrasil via optica. I have never tried an AVR nor pre/pro yet. I was thinking if I can grab a newer AVR (good pre/pro are quite expensive especially I'm still experimenting) and use its preouts, so that I could take some advantage of those more modern home theater technologies. Maybe I can also try a phantom center. In general, will an above average AVR beat stereo DACs like mine in processing movie tracks?
